Title: PS Audio DirectStream DAC
Post by: Doggie Howser on October 04, 2015, 17:58
I know we've been discussing this in the DSD DAC thread but I feel it's worth getting a dedicated discussion on it.

It's a long weekend here and I usually leave my amps and subs on 24/7 over weekends. So the amps have been on for 4 days now. The DS DAC has been on for probably a month fed by an old MBP 2010 running Windows Server 2012. Now with USB Regen.

And what a sound the system is producing. Every time I come back to this, it's just a revelation. Whether it's old or new songs, there's just so much in the music. The soundstage, the life-ness of the singer.

Right now it's Portishead with Glorybox

Durianlover, if you're ok with it, I'd like to reproduce your guide to optimizing playback on the device.

Go for it broler DH...I know you could not contain your excitement  :D

I have made a couple more adjustments...latest being the JS-2 and will be soon testing the 2nd Regen. If you are using non-USB cables pls share your tips as well.

Now  on Stimela......vroom vroom....woooooooooaaaaaahhhhh!!

I feel Yale and USB Regen complement each other. Yale brought new life to a lot of badly mastered songs even MP3. These days so many artists don't even have a CD quality release so having the odd MP3 which is unplayable makes it really hard to stomach.

Yale seems to unravel a lot of the veil that plagues most MP3s. Granted I still can't listen for long but at least it isn't as grating when they come on as part of a playlist. USB Regen takes away the digital harshness which makes my lossless sound more like vinyl. So the improvement comes across for MP3s as well.

Broler DH, seems your DS should be past 800 hours run-in, which would be the ideal condition to listen to the DS prowess :)

I haben tried the new Bridge v2...which would make the DS a streamer. Not sure it supports DSD files..

I believe it does if your DLNA supports DOPE

If you use JRiver, it should work. Bridge 1 worked too

Paul wanted to bundle Roon Lifetime with Bridge II at first because they worked very well. But they couldn't get it at a reasonable price so it was scrapped. I think Roon costs almost as much as the Bridge

Durian's tweaks

Quote

1) Uptone Audio USB Regen is a must. Sound went up 150% compared to without Regen....

2) I did change two pieces of fuses inside to Synergistic Research RED. This is a must.

IMO, Regen and Red fuses will do the trick. If you want to go max....I did some more below:

3) Ansuz Diamond USB...it is at ridiculously low price....1k+ SGD. Win Light Harmonics Lab Lightspeed 10G by a few horses...and much more emotional.

4) Ansuz Diamond Footers/Diamond power cord/Diamond Interconnect.

5) RGC24 below the Directstream...I have 5 units....but I find may not be really necessary now..the noise level is so so low now...

For me.. going to a linear PSU fanless PC made a big difference. Even better when I used Mike's 3Hz support platform under the linear PSU.

The USB Regen worked well too.

I am still using the Locus Audio Cynosure for USB

I had posted most of the benefits of DS in the DSD DAC thread. Optimizing DS not posted before...so the tips I have shared with DH are my learnings. Hoping to know who are the other DS users in this region (I know of folks following XP from Thailand as well)...pls share your tips as well. Some background as below:

Though i was a previous PS Audio Perfectwave combo user, my new romance with DS starts one day after its Feb Pikes Peak firmware release (after the significant 1.2.1 release Q4 last year). Ironically when broler Audio brought his 115V DS in Aug last year to AB with DAC2X, it was prior 1.2.1 release.  DS lost that AB. There may not have been enough hours on that unit and another suspect was the use of stepdown transformer. Prior to Audio's visit...there was another home audition of Vivaldi combo versus the EMM combo. The latter combo was retained though.

I asked A&L Andy to bring the demo DS unit loaded with new firmware to my place for audition. Played the EMM DAC2X for a while...then swapped in the DS....the rest is history.

I struggled for the next few months trying to sell the DAC2X, and pondered real hard whether to retain the TSDX transport...as connecting it to DS via Crystal Cable Absolute Dream AES/EBU yield mesmerizing music. I told my brolers only then did I realise how superb was the TSDX, eben though was only playing the CD layer of SACD. I need a music server that can play DSD64/128.

While working on my biggest project (office work) in first half of this year, I then struggled to identify a suitable music server. Thought to reuse my Core Audio optimized mac mini,  pondered Melco N1Z, listened to Lumin in showroom, tested broler Maverick built Windows Server2012 with AO,  but finally bite the bullet with Aurender W20 with HER Malaysia by trading in the EMM combo I purchased from them. The Ansuz Diamond USB was also released around July, and I also received the Uptone Audio Regen.  The combination is a bliss!

One other change I made is I had inserted the Audio Magic Beeswax Super Fuse at the digital circuit. Analog portion still using SR Red. This change is a good improvement too.

As much as I want to go Directstream full time, my Lumin S1 is still shining brightly and refused to be retired.  Second hand market for Lumin is very strong.  Directstream remains to be my secondary machine....hint hint.

(Audio)

PS:  My 115VAC Directstream is now a 220VAC machine.  I believe the power supply used for 115VAC and the 220VAC are one and the same.  The transformer is a 120V-0-120V unit and run parallel for 115V and series for 220V.  Another hint hint......

Yale Final firmware released end July is what we are listening now...but I was more grateful of the Yale beta opportunity when everyone in the world has a chance to voice their thoughts...who would have known Yale Final release was another significant up from beta!

With 50% of FPGA code rewritten and up to Yale releases really considered light weight...I am having high hopes of the next 2 firmware release..which are the heavyweight critical pieces. One release should come before year end.

Like this DAC because it is never finished :)
It is like buying a new DAC upgrade every few months but without spending $

Picked this from Roon forum:

"@Ratbert is correct on all points. We are working on the RoonSpeakers stuff actively, now that 1.1 and iOS are out the door.

I can't speak to the timelines of specific third party companies, but PS Audio has been very enthusiastic. It wouldn't surprise me if they were one of the first integrations.

We'll update with more firm timelines as we get there, but RoonSpeakers is the big project for us right now, just like iOS + new Metadata functionality was over the summer."

As requested.

Disclaimer:  I am not responsible or liable for any damage, harm or injury brought upon yourself or your Directstream machine.

This is the internal of the Directstream DAC.  Please look at the green wire block in the red circle.
(http://audio.sg/pic/psaudioinside.jpg)

For the 115V version, the wire links are crossed, like 2 primary coils in parallel.
(http://audio.sg/pic/psaudio115.jpg)

For the 230V version, the wire link are different, like now the primary coils are connected in series.
(http://audio.sg/pic/psaudio220.jpg)

The part numbers for both version is exactly the same.  The transformer use on both board are identical.

Good luck!

Come on, they charge you a hundred bucks and I think it is definitely worth it.  You look at the quality of the power supply, it easily cost more than that.  That board not only have conponents for power, they include the interface card electronics plus the SD reader as well.

In life sometimes, you must allow your manufacturer to make some money so that they can be successful and continue to support us.

Remember, they don't even need to entertain us....they could just tell us that the units are not voltage convertible to keep their international dealer happy....but they didn't.

Then, I see you in Denver next year.   I suppose to go to the PS-Audio factory tour this year tying it up with the Audiofest, return them my Directstream power supplies as well but dammn it, my retrofit aircraft schedule got in the way and that is why I was in Singapore / Hong Kong last weekend rather than in Denver.  Ayre is also near and I would probably plan to stay a little longer....and get my wife to come along as well.

How fortunes change....last time people dumped away the Directstream DACs....now used units supply dried up over the past 6 months...left only one unit at 4500 usd in Audiogon+shipping/insurance+PayPal fees. Even got wanted ads as well. Knew of someone in other forums promptly sell before run-in of 800 hours, and then re-bought the DS again :)

New Roon Discovery Server and Player unveiled at RMAF: http://www.digitalaudioreview.net/2015/10/rmaf-2015-roon-discovery-server-from-elac-americas/

Understanding is via RJ45, should be able play to Roon Speakers implemented on Bridge 2.

With integrated Roon life-time subscription (and Tidal) the price of Elac Discovery is favorable.


Roon Speakers is also, according to Roon, improve sq 'because the endpoint owns the master clock, taking advantage of the premium clocking in high-end end points'.

Just a gentle reminder....any Directstream DAC testing should note the following:

1) >800 hours run in on DS unit.
2) test with USB Regen pls if using USB, as USB interface is 'weak' by nature.
3) Streaming AB testing should be done with Bridge 2 inserted into DS to make it as a streamer.

Right… So I went to read up about RoonSpeakers (https://community.roonlabs.com/t/roon-speakers-what-when-how-and-for-whom/290) on the Roon Forums. Was a little fuzzy until I came to this post from Brian;
Quote
RoonSpeakers is just an audio transport mechanism, so Aurender + RoonSpeakers would still require an external Roon server running on another box…

So it looks like RoonSpeakers is a proprietary rendering end-point for Roon Server. And other vendors would need to implement it on their devices (like PS-Audio on their Bridge2, or iOS client etc.)…  First thought was: Hello! DLNA DMR/DMP? Why reinvent the wheel and force device manufacturers to implement yet another client protocol? And then I caught this post from Brian;
Quote
Quote
What are the advantages compared to other protocols like AirPlay, Meridian MQA, RTSP, DLNA,UPNP?
In short:
  • It doesn't compromise on user experience or compatibility (unlike DLNA/UPNP)
  • It doesn't compromise on sound quality (unlike AirPlay)
  • It doesn't compromise on reliability (unlike RTSP)

Not so sure about the user-experience issues for DLNA (I haven't experienced any real "issues"), but the other 2 points makes sense! ;D
 
ps: Even dCS is on the list of Roon hardware partners, with the new Rosini player apparently already supporting RoonSpeakers… (I’m wondering if thats what the latest version of dCS’ network firmware update for the Vivaldi issued 2 weeks ago is… Maybe I should revisit Roon after all  ;)).

I think DLNA is UDP based which means real time but potential for errors. I suspect Roon is using regular network packets and reassembles on the back end. IMHO not unlike a Mac/PC reading off a NAS so it is less dependent on timing/clocks and network interconnects
Title: Re: PS Audio DirectStream DAC
Post by: AndrewC on October 15, 2015, 16:03
I think DLNA is UDP based which means real time but potential for errors. ...

Correct… DLNA relies on RTSP for packet transport, which typically uses UDP (to get near Real-Time delivery).

That said, RTSP (RFC 2326 (https://www.ietf.org/rfc/rfc2326.txt)) can also negotiate TCP for packet transport, but I suspect because TCP’s windowing etc requires heavier processing, makes it more “expensive” to implement for most consumer clients, so most end up sticking with UDP options for transport ;)

It’s the same/similar issue discussed in the Merging NADAC/RAVENNA/AES67 thread not too long ago.

Latest info on next Directstream firmware release:

"Ted Smith said
People are asking me to slow down (especially print magazines like Stereophile, TAS and HiFi+) We've been two releases ahead of published reviews in the past. Also plenty of people on this site have said the same.

I've been busy with a few other projects (don't ask, you'll hear about them in due time if they work well) but I expect to get back to working on the next software release November to December (or possibly January). The work is a little harder than the last couple of releases so it'll take a while. Also we need to coordinate the release with other PS Audio releases. So I'd guess not earlier than next Feb or March.

Hopefully that answers your question."

Post by: Audio on December 25, 2015, 13:15
I sense the Lumin A1 would not sound as good as the Directstream. The  A1 was never on the hi fi rack long before Pikes Peak was available so, no chance to directly compare.

Like I said, in recent firmware upgrade, Directstream is sounding very good and both Directstream and Lumin S1 are sounding close with various pros and cons.....no clear winner, different tracks, different properties.

I can live with both but if you are not me and you are coming into the market for a DAC now, it is a no-brainer which DAC you should be buying.  :)

That's one of the reasons we created the new and upcoming DirectStream Transport – which will do exactly what you want – stream true DSD to DirectStream. There are many legal hurdles to doing this and we got through ours by coming up with an encryption scheme so the new transport will output DSD only through I2S into DirectStream."

PS-Audio finally catching up with what Accuphase, Esoteric, EMM, dCS, and Playback Design (and probably others) have been doing for years… Encrypted DSD transmission between transport and DAC :).

I didn't know PWT read SACDs though... thought it's only CDs/DVDs?
Title: Re: PS Audio DirectStream DAC
Post by: durianlover88 on January 10, 2016, 09:03
When I was using Perfectwave Transport a few years back, sacds were not supported.

This new Directstream Transport will be using Japanese sourced sacd transport (Paul did mention transport is Oppo-based). But I think it may be a Long shot if it turns out to be some lower tier Esoteric transport, since memory play/digital lens are always in PS Audio DNA (following what was done in PWT), and they might want to keep the cost down and price the transport at low price.

Some folks might dismiss Oppo-based transport, based on their experience with Oppo players. Me think otherwise. It is all about the implementation. Example my Theta Compli 3D universal transport is based on Oppo 95, but beat the hell out of all Oppo 10x, no matter how high they have been modded.

Had used PWT/PWD combo before with Audioquest Diamond HDMI as I2S, before switching to EMM. So it is like a home-coming back again for me :)
Title: Re: PS Audio DirectStream DAC
Post by: Doggie Howser on January 10, 2016, 10:29
I guess the lack of an SACD transport is likely linked to the original PerfectWave. It wasn't a DSD DAC and there didn't seem to be any reason to include an SACD transport.

The DirectStream was designed to use the same chassis and also sold as an upgrade kit.

FWIW I think the Oppo transport is likely to be the way forward in the future since Sony has stopped producing the chipset used in Esoteric transports. MSB also uses the same transport IIRC

DL88, where did you read that it’ll be a Japanese sourced SACD transport?? As you said, Paul says they’re working with Oppo and using their mech, in which case it’d be Guangdong sourced Boulder modded :P

One question still: Will the PWT II also play DVD-Audio discs?

That’s a great question I do not know the answer to. If the Oppo does then we do since it is based on their drive mechanism.

is it going to upgradable from the original pwt?

No. It’s an entirely new set of guts, back panel, bottom panel and front panel – I think perhaps the top cover is the same. We will be doing our best to offer substantial help with trade ins – as we always try to do.

The output for SACD raw DSD will be through I2S – and not just one I2S. We will have 3 I2S outputs so multi-channel SACD can play raw DSD into multiple DirectStream DACs for those interested in multi-channel.


The new DirectStream Transport will likely be $4,999 – a bit higher than the original $3,999 of the PWT.

Interesting, fairly steep pricing. Also surprising they’re going down the (OOP) EMM Lab’s TSD1 path for multi-channel DSD output. Paul should know better… it’s been proven there isn’t a big enough market for multi-channel SACD.

Curious that PS-Audio is going down this disc transport path in this day and age… Personally, I think Playback Design has one of the more elegant current solutions to this whole issue surrounding SACD transport, their OpBox - Oppo daughter card with encrypted Optical output (PLink) into their DACs and integrated 5-series players. Very elegant (albeit not cheap).;

Indeed, thanks and yes, there will be a PWT II out this year – I have been listening to it play SACD directly into the DirectStream DAC and it is to die for. I will say this with confidence – if you own SACD you have NEVER heard what’s really on them – …

DL88, where did you read that it’ll be a Japanese sourced SACD transport?? As you said, Paul says they’re working with Oppo and using their mech, in which case it’d be Guangdong sourced Boulder modded :P

That’s a great question I do not know the answer to. If the Oppo does then we do since it is based on their drive mechanism.

Not sure about Angmokio, but my 6-Sec Yishun method sure works everytime. I always worry the transport will spoil fast with frequent on-off.

PWT uses memory play reading of discs and buffer out through Digital Lens with Reclocking. After ejecting the CD, music will still play until all Digital Lens buffer data are clocked out.

Yup, I read that. Makes little economic sense to me though… why include multichannel hardware capability (for a tiny market), and have it priced into the transport at $5K?… You should recommend to him to use an optional daughter card instead for the two additional I2S outputs (like the Bridge card), don’t need, don’t pay :)

Can say the same issue with cartridge stylus too.
The more you play the more the stylus on the cartridge wears out.
Yet people still want to play vinyl.
Why?
Because life is too short to worry about these insignificant things.
You might be here today and gone tomorrow.
"One day you cross some line and you were too much in your world..."
So the don Henley song goes.
Anyway people change hardware in 2 - 3 years anyway.
Some even faster.
So again why worry?

Some transport and DAC and minimise the sonic differences between whether got angmokioing or not.

By minimising I don't mean covering up the inherent sonic differences with euphoric colourations.

I hear real audible sonic consistency transitioning from track to track.

The Emmy combo is one that I can say I can listen to the entire disc from beginning to end.

The transport made by Stream Unlimited (the former engineers from Philips cd pro disc drives) is also one such devices.
Very minimum changes when one track ends and the next track begins.

The shigaclone transport that bro btw loaning to me is also one such devices.

He also specially made it so that the tracking buttons are all on top so that I can do the angmokioing more easier (based on the feedback from listening tests we did with his earlier prototype)
He also made the chassis all from wood.
How cool is that...?  ;D ;D ;D

Otoh the oppo based transports are the worst performers.

There is fcuking big differences in sound between the first track (after doing angmokio) compared to the rest of the tracks. And oppo based transports can only do angmokio for track 1 and not other tracks. That's why I say oppo sucks big time. Any transport based on oppo design is gonna suck too.


Title: Re: PS Audio DirectStream DAC
Post by: durianlover88 on January 10, 2016, 17:44
Don't be too sure yet...I will wait for the real thing to come, listen first before concluding.
Oppo does not do memory player (RUR), buffering mechanism unknown. We don't condemn a transport because cannot AMK.

My Aurender W20 does SSD caching and reclocking as well. As I play the songs they never waver in terms of playback consistency. I don't need to switch it on and off to play each song.
Title: Re: PS Audio DirectStream DAC

When the system need to depend on tissue paper, wood only, half cup water, cable cannot touch curtain, and off and on the transport for every single song - this goes to show system fundamentals are not sound and unstable and too dependent on every variable factor. It is not a favorable state to be in. Too lache...to each his own.

when you put a black curtains in front of a stage you wont be able to see the performers behind whether crying got use tissue paper, whether the furniture props are made of wood only, on whether the performer is drinking from a half-filled cup, or whether the drink is real brandy or just water.

you are not able to see what's really happening on stage because your curtain is down. that's why.

lift your "curtains" so that your system may start to allow you to hear the sonic changes and help you to understand why cables cannot touch curtains and why amk is required.

pls lah, everybody's system will have wholesale sonic changes when speakers are shifted even a micro millimeter.
its not only your system.
this is macro differences that nearly every system will be able to let the listener hear.
is like everybody can taste the differences between North and South indian curry.
but maybe not everybody is be able to perceive the taste differences between rice grain varieties.
maybe it takes a real connoisseur to do that.   

cables touching curtains often does something to change the cable dielectric characteristics that will manifest as changes in frequency response and frequency extension further downstream.

Saw these couple newsletters from Paul yesterday and today, that could act as references:

<What matters most>

In yesterday’s post I suggested that to answer to the age old question, are bits just bits, requires us to first change the question.

The question we should be asking is, how can identical bits sound different when played back on different hardware.  Asking the opposite–how can identical bits sound different–is a circular question with only one correct answer: they cannot.

For clarity sake, let’s all agree that stored data is the same regardless of its storage medium: solid state hard drive, mechanical hard drive, USB stick, optical disc. Armed with these sets of facts, let’s dive in and see how things might differ.

Take for example the fact that nearly every CD transport made sounds different, then add to that disc treatments, like cleaning and optical enhancers, seem to further improve performance, and a pattern begins to emerge. Identical data sounds different depending on the mechanism delivering that data.

Optical data has no timing information included on the disc itself. Same with hard drives. Data, is data. Timing information associated with retrieved data is added later. In the case of a transport, a variable clock is used to send bits out to the DAC. That clock within the transport becomes the master timing element for the DAC – and it must be variable. Why? Because the output speed of the optical reading mechanism varies according to the quality of your disc, and where it is reading–beginning, middle or end. These timing changes are what make the audible differences, not the bits themselves.

Realizing what causes these issues is what lead us to develop the PerfectWave Memory player. Simple in concept, the memory player uses a big buffer to store the data retrieved from the disc before delivering it to the DAC. Why does that matter? It matters because of just one thing. It permits the use of a fixed, low jitter clock–where all other transports must rely upon a higher jitter variable clock. Is it perfect? No, certainly not. But we arrive closer to perfect by employing this simple idea.

Viewed from afar, it’s tempting to think the memory player is performing some magic–because discs just sound better. But the truth is, it isn’t better, it just isn’t as bad.

And perhaps that seems a silly distinction, but I would argue that demystifying magic helps us understand what’s really going on in an increasingly complex world.

Tomorrow, let’s look at why solid state vs. mechanical hard drives sound different.


<Armchair critics>

It’s easy to ignore–often criticize–the hard won victories of creative people designing leading edge technology. In fact, it’s one of the double edged swords of our abundantly-connected society that empowers readers with just enough information to miss the bigger picture. And this is part of the problem I find in helping unravel the workings of audio – and explaining the mysteries of differences in sound quality when none should be there. For when we wave our hand and suggest they should have done a better job, we gloss over all that does work well.

Take the relationship between a DAC and its source as an example. The architecture of the CD playback system was originally developed in the early 1980’s as an integrated device; a transport and DAC in one box. Within that box the optical drive supplies the master clock to the DAC through a variable timing mechanism; its variability essential to accommodating disc variations.

Variations in the master clock result in increased levels of jitter, reflected back to the listener in degraded audio performance. Armchair critics can suggest that DACs should have been designed as independent entities–instead of slaves to the source–and few would argue in hindsight. However, let us not wave our hand in a dismissive gesture. I find it more instructive to understand and appreciate the mechanisms behind the technology, even if they have flaws, rather than brush them off like a bothersome insect.

I suggested in yesterday’s post that different types of hard drives present music differently. I know this raises the eyebrows and hackles of many. But, I can tell you with no uncertainty that a solid state hard drive inside my Mac Mini server sounds markedly different than a mechanical one. Want more? The type of RAM employed matters too. How can this be? Data is data. Bits are bits. Right? Well, it’s true only in some cases.

A solid state hard drive sounds identical to a mechanical hard drive only when connected over a network, but different when powered by a computer connected to a DAC. Power supply variations in computers attached to DACs increase jitter levels in the same way that jittered master clocks in CD transports do. But, network connected storage is different. It is physically isolated from the DAC and the device feeding the DAC.

Jitter can result from differences in power supply and processing demands. Want to learn more? I would recommend re-watching our DAC designer, Ted Smith, in his series on what jitter is and why jitter matters.

Fresh updates on availability of new firmware for Directstream....below extracts are from 4 posts by Ted Smith over the past couple days:

" have the software written and compiling well.  I’m still debugging it and that’s a process that may finish today or in a few weeks depending…  After that we need to listen critically to see if it indeed sounds like I think it will of if we have to do some serious tweaking.  Then PS Audio needs to work it into a release schedule.
I do like the way the new software is coming out.  Some of the code I rewrote was written quite a long time ago and I’ve learned stuff in the mean time but you always do better the 2nd (or 3rd, etc.) time you rewrite things – I’m getting more done with fewer FPGA resources and the code is simpler."

"I’m hopeful: in the C++ simulation I got a 3dB lowering of ultrasonic noise.  Whether that difference will be audible I don’t know, but it can’t hurt.  The new software will also have a measureable difference distortion of loud low frequencies, but once again it may not be that audible.  I think that the changes in jitter may actually be more significant: we still have to listen to be sure, but we did get a noticeable difference between Pike’s Peak and Yale with similar jitter work on the front end of the FPGA DSP chain.  We may even slip in a new feature or two  :)"

Title: Re: PS Audio DirectStream DAC
Post by: durianlover88 on February 08, 2016, 09:14
"Pike’s Peak to Yale was a rewrite of the input side: the PCM upsampling chain (from the input sample rate up to 176.4k or 192k) and a reclocking of that input processing and PCM upsampling chain with the goal of lowering jitter.
The next release is a rewrite of the output side: the up sampling of all inputs to 28.224MHz and the sigma delta converter and reclocking those with the goal of lowering jitter.  That rewrite enabled some significant improvements in the sigma delta converter which is where the measureable changes mentioned in a previous post happen.
The changes in this release don’t know the difference between DSD and PCM inputs, they do identical processing for all inputs and hence any improvements should happen across the board.
I can’t promise any particular specific thing like “a warmer sound”, but I’m sure this release will continue the trend to provide more detail without becoming analytical or clinical.  The goal, as always, is to do less harm to the input signal and be more faithful to it.  But lowering jitter will probably give more detail, a blacker background, more air around the instruments/voices and hence a more precise soundstage without changing the frequency response.  The changes in the low frequencies may provide a firmer bass which often leads to a clearer feeling of the timing/PRaT and hence more musical involvement.  The lowering of the noise level in the high frequencies/ultrasonics may also add a little more air and ease, but no promises there.
I don’t want to oversell these potential changes – as always, just because something is measureable doesn’t mean it’s audible and conversely some of the more audible changes aren’t easy to measure.  But we’ve always found lowering jitter to be an improvement for almost all customers and so far I haven’t found any downsides to anything I’m doing for this release."

"My whole premise has been that people don’t take jitter seriously enough.  Thinking purely in terms of lowering noise goes quite a ways towards lowering jitter, but there’s more to lowering jitter than just paying attention to power supply noise, component noise, clock noise, etc.
I made the mistake of assuming that extensive power supply isolation and bypassing around the FPGA along with a very good reclocker would be fine for handling jitter out of the FPGA – as Arnie can attest the different ways that the FPGA gets the identical bits has a significant effect on the resultant sound.
I’ve seen good audio hardware designers argue about whether you can use an FPGA in an audio product at all.  In one case one fellow was claiming that you could control the noise out of an FPGA with good engineering and the other claimed that you could never get control of it.  The DS shows some ways that both are right and both are wrong.  I suspect that the first was using an FPGA much earlier in the signal path and that the second never stumbled on to the concept of using a good ear to wade thru a bunch of compiles of identical code to find the ones that did the least damage (or perhaps he never took jitter seriously enough to begin with.)"

Not surprising actually, the Spartan-6 LX16 chip costs something like $26 per unit… I can’t imagine Ted wasting his time re-coding for another chip… (Unless they were trying to hit some portable power/size requirement… which they could still do and compete against the Chord Mojo ;))

I doubt they'll have to maintain two source codes, likely just one but with compiler directives inline... so the actual firmware will likely be different for each box.

I recently got back on the vinyl bandwagon.

Mainly because I got a lot of guidance on how to set my turntables properly.

But mainly because I discovered I actually bought Hell Freezes Over from the Simply Vinyl reissue a few years ago but forgot I owned it till recently.

So I have been getting a few new records. JB HiFi while not the best "HiFi" store does stock an amazing range of new vinyl and they aren't too expensive either.

I got Random Access Memories a few days ago and got around to cleaning it first before playing. I've noticed there's a lot of noise because they apply some chemicals to pull the record off the mould after pressing.

Anyway I started playing the record and it was really good. But I know I have this same album on 24/88.2 so I figured I'd give this a play on the DirectStream. Bear in mind I'm using a MacBook Pro 2009 with the switch mode PSU as my source passing through admittedly some nice USB cables - Locus Cynosure and Curious USB through an Uptone Regen with regular wall wart power supply.

And you know what - the DirectStream didn't lose out. The vinyl has a slight edge when it comes to playing at louder levels - there's not as much digital glare that makes it a little harsh when you listen at very loud levels with digital normally. But you know what I was listening to pretty high levels on the DirectStream without any wincing.

On balance, because of a lot more material I have on digital, it makes the DirectStream a bit more accessible.

I can't wait for the upcoming Transport that will play BluRays DVDA and SACD!

PS audio coming up with a BR/DVD/SACD/CD Transport ??

Paul McGowan's post on Friday:

'We’ve been working a good amount of time on a new transport, one that’ll be the first in the world legally capable of rendering SACD content in pure DSD form to an external DAC. It’s a big deal, a tall challenge and one that’s got me quite chomping at the bit.

But along the way we were forced to make a decision. Should the new transport be audio specific, or should we broaden its scope to include video? Said another way, do we narrowly focus the unit’s purpose to limited appeal, or broaden its focus to gain wider acceptance? And, second question, why would the answer to that not be obvious? Isn’t it always better to be all things to all people?

Creating anything comes with risks: painting a picture, a new clothing line, car, tire, cable, novel, transport, and so forth. The risk is simple. Will anyone like this enough to adopt it? Just look at our new magazine, Copper (yes, please do, it’s awesome :)). When we created the magazine we had to make a number of decisions, chief among them–who are we writing for and what are the risks in doing so? Not everyone will like it. Some have already decided they don’t like it at all. In fact, several people have objected to a few article so much they never want to see it again. That’s price of narrow focus. So, what’s the rewards?

Purity of content.

We understand there are no perfect solutions. Each decision we make has ramifications, both plus and minus. By building an audio only transport, the audio you get is noticeably better than if we had included a video output on the transport. The video processing and signal radiation detract from the audio. Each time we broaden the appeal, we dilute the product’s performance.

It’s always a tough call for any creative enterprise but, in our experience, the purer the purpose of our creations, the better the results for those who appreciate what it does.'

Yeah...video use a BR player la..dedicated for audio better.

The only Universal transport that is acceptable is Theta Compli Blu 3D, but for SACD it has to use HDMI to AV Receiver. Other interfaces are not encrypted and DSD got converted to PCM....so Directstream transport is the godsend needed :)

Upcoming Directstream & Bridge firmware is code named Torreys Peak in Colorado...Sneak peaks from Paul on Friday:

'No, Torreys plus a new Bridge update, will permit Bridge II to become an end point for Roon (and their RAAT) if you want. UPnP is still enabled so customers who want to keep doing what they’re doing with UPnP won’t even notice a change in the Bridge. If you’re running a Roon server already, all of a sudden you’ll see the Bridge II pop up as one of the devices you can play to in Roon.
Torreys will be the biggest update we’ve ever had. Ted’s redesigned much of the FPGA code, lowered jitter even further, and knocked it out of the park sonically. More than that, Torreys will permit, for the first time, native DSD over USB. I know that’s a big deal to a lot of people (though DoP has never been an issue for me). There’s lots more coming down the pike.
Torreys will be available in two versions, one for DS the other for Junior. Both benefit tremendously.'

It’s posts like this that makes Paul lose all credibility… Accuphase, dCS, Denon, EMM, Playback Design, Pyramid, Sonoma, Sony, (probably a few more that I’m missing), ALL have (or have had) fully legal means of rendering pure DSD from a transport to external DACs.

PS-Audio is just the last one, and somehow Paul can turn it around and dares to claim to be the first?!?… What’s worse is talking crap about another vendor to justify his claim; http://www.psaudio.com/pauls-posts/narrow-focus/ (http://www.psaudio.com/pauls-posts/narrow-focus/)

I think you misunderstood the post about EMM. My reading was that EMM was trying to find a way to rip SACDs and it was that plan that fell apart.

Maybe there's something unique about the I2SDSD stream?

Paul, I’m a bit perplexed at this statement:
“We’ve been working a good amount of time on a new transport, one that’ll be the first in the world legally capable of rendering SACD content in pure DSD form to an external DAC. It’s a big deal, a tall challenge and one that’s got me quite chomping at the bit.”

The perplexing part is the “first in the world” statement. I was under the impression that DCS, Meitner, and Esoteric (maybe others too) had multi box systems that passed the DSD stream from an CD/SACD transport to a DAC via an encrypted link. If I understand them correctly aren’t they the same? If not, please explain the difference.

And Paul’s response pretending as if EMM’s Optilink is either illegal or doesn’t exist;

And he pretends to not know about dCS as well in that same post…

As for DcS, I never pay much attention to them and if they do have a pure DSD solution that works into their DAC without HDMI it is news to me and I should stand corrected. Though I see nothing on their site that indicates it is so.


Complete bullocks.

No lah, it's a not question of me being kan cheong or anything... There's marketing spin, and then there's just outright lying... Thus far it's just been harmless hyperbole and marketing spin from PS-Audio/Paul, but lying about the market and what’s worse lying about another vendor is totally unacceptable.

Paul’s McGowan is being dishonest.

No doubt there are informed PS-Audio users such as yourself, but there’re generally far more uninformed users around, who are being lied to. That's just not right.

Teasers for PS Audio folks:

Ted Smith:

'I’ve written what I wanted to write, I’ve been using it for a while now along with some other alpha quality code for other parts of the Torreys release and things sound good and the new FPGA features seem to work.  On the other hand there’s a lot to test when you touch the majority of the code and there’s also a lot to test in the rest of the system.  I don’t envy PS Audio getting this release tied off and out.'

Paul McGowan:

'Ted’s finished his part – and it is truly a masterpiece – DirectStream and DirectStream Junior have risen above the clouds once more!
We are waiting on the microprocessor changes, then the final evaluations by Arnie before release. Also hoping to squeeze Roon in there too.'

Wait is excruciatingly painful...

MSB one is selling at US$6995 to 11995.  Think in his video, he mentioned something like US$6K  ::) ::)

By using oppo - mean also have LAN + maybe able to stream directly into the transport from network NAS ???

Make that… third or fourth guys!! ;D

Not just MSB with their XPORT (http://www.msbtech.com/products/universalV.php?Page=platinumHome) Oppo upgrade to output pure DSD to their DAC, Playback Design also has a (fully legal) retrofit for the Oppo called the OpBox (http://www.playbackdesigns.com/#inline_content_OpBox) that uses a stock Oppo to output an encrypted Optical interface to their DAC. And there’s Goldmund who OEM the Oppo for their Eidos 17 (http://www.goldmund.com/en/products/eidos_17), though they use the standard HDMI based DSD output into their Processors which accept HDMI DSD bitstreams, all fully legal as well.

(If you listen to PS Audio’s Paul waxing lyrically about the DirectStream Transport, it’s as if PS Audio is the first and only one in the world to legally use Oppo to output pure DSD ::) )

I think it isn't just a mod - they are disabling the video circuitry, which seems to offer an audible improvement and they are using their digital lens circuitry - bypassing the Oppo's own - sending it to 3 I2S for multi channel DSD.

The DirectStream Jr is A$5999 now. Normally it is A$6795.

I suspect the difference is closer than 85% but they just claim 85 so they don't make owners of the full DS angry.

Not a big fan of the Lumin looks and I'm also getting the nuwave phono converter to rip all my vinyl to DSD too so I can use the I2S interface also direct to the DS J or NWD. The DS J while having the network interface is 3 times the cost and if I did get rid of my prepro that I use in 2 channel mode I could have the extra funding to go with the DS J I suppose.

Mine about 500GB for ~15K files
~ 99% in FLAC zero compression.
~ 90% in 16Bit 44.1KHz type

Like that 1 TB SSD will do the trick.
Or if there is a 2TB SSD ? lagi better

I'm hosting both formats AIFF & DSF with zero compression on former in my NAS.
~50GB for AIFF; ~1.3k files
~800GB for DSF; ~4.4k files
~2x% duplication between AIFF & DSF due to double dip.

I have been ripping my entire collection ~3xx discs. 2/3 completed so far and spinning them on 50:50 on both my CD transport and Streamer.

As such, Aurender A10 with 2TB offering, good enough for a typical music listener. SSD is the way to go. I'm sitting tight for A10 while enjoying my Lumin right now. "Simplicity over complication"

The rule is I can't ship it out of Australia - there's nothing to prevent someone from buying it in Australia and then carrying it home. Not unlike how guys in Singapore head over to HK to buy and carry back gear.

I've worked with both Paul and his team there before on a few local repairs here that seemed to be no issue but not sure if they tried to get them repaired at the dealer before I looked at them.


As I was going to be up the rd from them in Denver I said I'd like to drop in. I'll be given the tour and get to hear Torrey's firmware in the big DAC and hear the LANRover too, and maybe new oppo drive transport in alpha stage too. Experience room on rep with the big IRS system too. Should be a treat. Much better than my visit to Emotiva last year I'm betting.


They offered to let me buy anything I wanted too, using the USA store and treat me like any USA client as I'm on their soil. What I do with it after that is my business.

A visit to the PS Audio offices today...Met Paul...wished him happy birthday today too. Met some of the design guys and saw some prototype stuff too. Got to play with the new BHK Preamp, the DS DAC and NUWavePhono and NuWave DSD too.


Might go back for a 2nd round in a couple of days too. Nice bunch of guys and a big difference from the Emotiva cowboys :P


Room one listening room with the IRS-V's awesome wall of sound.

I was told it was ok to post the image of the transport so I guess its ok. I might get out there again and maybe get some more pics of new things...see how I go.


its based on the BDT101CI drive and I think its using the internal OPPO board at least for their testing with modified firmware. I think they were testing with Torrey's that was working on the DS DAC but the Junior was having some tweaking done...as the platform is different enough that the code is not identical.


I think they had Torrey's running in the music room on the DS DAC. Room is close too I think.

it based on a OEM but as I understood its been tweaked to better specs etc for PS A. seems to benefit from the galvanic isolation on the LAN ports, but I didn't get a chance to AB with it out of the link. they seem to like running back to back via a short LAN cable.

Wiz, if you press PS Audio on it, you'll realise that the "galvanic isolation" they talk about is stock-standard transformer coupling on the Ethernet balanced pins, nothing special; every Ethernet port is that way! Ask them (and don't take Paul's B.S. marketing spins for answers :) )

they are selling sprout in the USA for 499, and doing a package deal with ELAC B6 speakers I think and Emotiva speaker cables (yeah I kid you not) they also like the curious USB cable.

The LanRover should ship late June at US$599 i was told today. The reworked the code over the 6-9months with the developer and changed the internal design from PGA to dedicated IC making big improvements AFAIK and so its a specific box for PSA product. of course can use with any USB in/out transmission so should work with all USB DACs remote from the Computer/NAS

When I had the chance to sit down and do some critical listening, I grabbed at it (hint the next door tea shop doesn't appreciate the high quality or high(er) levels of music).
 
It's hard to imagine how Ted Smith could still improve on Yale but he did.
 
The biggest change for me was in the initial attack phase of instruments.
 
One of my go to tracks is Max Richter's Four Seasons Reimagined - Winter 1. I had never heard such delineation of the strings and double bass - particularly during the attack phase. It is soo well defined. That piece of music has always been powerful but hearing it with that precision and detail was just downright emotional.
 
Bloody. Awesome.
 
I can't wait for the DirectStream Transport to be out. Might shelve the need for the fat PS3 ripper now since I can play back my SACDs in all their glory soon.

It'll be interesting to see if Ted reveals the specifics of changes he made...

dCS revealed privately the specific of their recent monster firmware upgrade; it's not public domain so I'm not going to elaborate, but it has to do with significant timing and digital filtering improvements via the FGPA code. The specific issues addressed are well understood and documented (in AES papers going as far back as 1998 believe it or not!), but it's only now that such previously theoretical-only efficiencies can be delivered in consumer grade platforms ;)

"When I first started this project I was a little apprehensive about having to voice the result.  I didn’t know if putting a little dip in the FR or, … would make it sound better.  I didn’t know if I’d have to listen to every possible component in each possible position of the device…  (A slight exaggeration  :) )

The first few prototypes I built I built with varying quality of components so I could hear the differences with them.  The first proto type sucked – I could hear differences between the three grades of component choices I built, but who cares?  Overall the sound wasn’t good.  The second prototype was worse.  For the third prototype I just decided that I’d do the best I could on every decision, no matter what the cost and if that didn’t sound good I’d quit.

I did sound good, darn good.  Then the real issue was could I build it at a price point that people could afford and keep what I liked about the sound.  …

With the first DS’s that we got back at PS Audio we weren’t completely happy with the sound but it was pretty good.  As Paul and I (and later Arnie) listened and found things we didn’t like or thought we could do better I’d think about what could be wrong to cause that fault.  We nuked some output caps that were just their for FCC/EMI reasons, the DS was quiet enough we didn’t need them.  We nuked a little of the passive filtering.  We found one place in the circuit (which was replicated eight times on the board) where changing a resistor to a lower value than expected made a good difference in the bass, and ironically changing it from a quality metal thin film resistor to a slightly cheaper metal thick film resistor made things sound better.  Paul had engineering change the other thin film resistors to thick film and see what changed, but as I expected they just made things worse.  The one we did change wasn’t really in the audio path, it set a “bias” voltage, but to be honest I have no idea why thick film was better there.

Anyway thru that whole process it became clear that (with the exception of that one resistor) the best sound was always had by using the part that logic and a careful read of datasheets said would be the best part.  There wasn’t really any need to plow thru all different brands and designs of resistors/caps, etc.  We didn’t need to try different opamps, etc. we just needed to understand the parameters that were most critical in each situation and choose the best available part or at least an affordable part that got the job done right.  Similarly we got the best sound with the flattest possible FR – (I should say that the best sound was gotten by designing the FR to be flat, not using some sort of graphic equalizer to flatten the response.)

Then in on the software side as Paul, Arnie, and eventually you guys gave feedback once again the best sound was gotten by fixing bugs and doing the best theoretical thing I could at each step.  As time went on we’d discover things that could be done to save some FPGA resources and then I’d use those resources to do something else better and each release got better and better.

Overall I’ve been trusting but verifying that doing the right thing got the best sound.
Don’t get the wrong idea – the hardware and software aren’t perfect (nothing is, especially for an affordable price) so Arnie listens to many different compiles of the code to find the most realistic sound.  I interpret his work as finding the version of the software that gets closest to the reproducing what the mastering engineer heard but that I can’t measure on the bench (yet.)  We know that it’s not just random because as I learn with each release we get better sound and the 20 compiles for a possible release generally have less and less variance as time goes on.

Here’s my test list – I play thru at least the beginnings of each (annoyingly quickly for anyone else in the room) anytime I change something in my system or in the software or when I visit someone else’s system (at least if they don’t mind me doing it):"

Thanks for that! ;)

The text you quoted though, seems to mostly just general commentary from when the DS-DAC was originally launched, rather than the firmware upgrades per se... I recall reading them before. But the links you included (that Ted pointed to) though have some very interesting bits in them… That said, while he talks about changes in Torreys to things like the digital Delta-Sigma modulator, he doesn’t actually get into the specifics what those changes are.

BTW, I just noticed the note from Denis saying that Bridge2 will never support native DSD (without DoP)…

http://www.psaudio.com/forum/directstream-all-about-it/after-yale/page-3/#p54092 (http://www.psaudio.com/forum/directstream-all-about-it/after-yale/page-3/#p54092)

… As for native DSD, the BridgeII will never support native DSD, only DOP.

…I wonder why. IIRC, in pics Audio posted of the B2, there was no fixed PCM framer hardware and there was an FPGA and an ARM9 processor… I wonder what the limitation is.

Directstream need to self initialise on it's own without the SD card because it works.

The sound is up another notch.  Quiet background , solid tone, great soundstage precision.  Lumin just sounded a little more detailed and preferred than Directstream still....perhaps due to some monocrystal cable someone sold me....  :)

With 50% of FPGA code rewritten and up to Yale releases really considered light weight...I am having high hopes of the next 2 firmware release..which are the heavyweight critical pieces. One release should come before year end.

I have been saying that all along.  I got both DACs and I listen to the Lumin more because it sounded more detailed.  Yes lah, Lumin is only Hong Kong brand...so, not everyone would consider.

But Directstream sound is good and gets better with each firmware update.  If don't have Lumin to compare, I would also think that it is the best sounding DAC for it's price.

But Directstream sound is good and gets better with each firmware update.  If don't have Lumin to compare, I would also think that it is the best sounding DAC for it's price.

Lumin which model you're referring to ?  Hope not the highest end model.

I think closed to 2 sets of DS+Bridge 2. A1 minus alu block still not T1. The isolation in A1 is the gap between both.

LOL.....what you didn't know is, my Lumin also got good upgrade....monocrystal XLR. 

Good sound is not just straight forward.....you got all aspects to consider, details, speed, sound stage, tone, darkness....

PS Audio Directstream is "more control, more 3D, more gaps between the sounds"
Lumin S1 is "even more details, a little more tone neutral"

If I got one source, obviously I will be excited with each upgrades.....but if you compare........then...it is a matter of preferences I would think.

Not really cranked it up...buts it's been powered on now for over 24 hrs so will maybe get a chance on the weekend to do some listening. Likewise for the nuwave phono converter


Usb connection seemed to be rather bad so maybe the Mac is trying to push it at more than 24/192 but haven't checked that yet. Also the nas playback direct seems to connect but the interface on the remote doesn't update the play time....not sure if that's a remote issue or actual config issue but will have to look at that too. Oppo coax out to the junior seems to be working.

I don't know but I think I like TorreysB better than TorreysC.  TorreysB is darker, more spaced out, I love the gaps and I think it is more controlled.  Now with TorreysC, more weight but lost the spaces and less controlled.

Switch back to Lumin, OK, Lumin can still stand on it's own.

In the process of running in TorreyC non-stop before the 3-5 sec critical listening...noticed the FPGA takes a while to settle down after each firmware upgrade...but initial reaction is an all round improvement again for me. More relaxed than TorreysB, but can picked out all the ambient components easily. Musicality up again, natural, relaxed, yet still toe-tapping. There are a lot more textured bass now that I neber heard before...lucky my room and speakers are up to task for the bass department :)

I'm a bit late to the Torrey official release.

Torrey A was so good I didn't want to change a thing.

Had about 30 minutes through my Bocelli playlist tonight after updating to Final.

My initial impressions - Final gives me the wide soundstage that I got with Yale. It seemed to have a narrowed a bit with TorreyA. But TorreyA gave me such clear delineation between instruments, I was happy with the compromise.

Torreys Official still gives me the ability to hear each track and instrument like TorreyA but without that keen sense of delineation. It's a more cohesive and realistic representation, I feel.

I like the vocals air, ambience, darkness and seduction when the music come out from darkness, for TorreysB. Noise floor is in fact very very low.

Torreys Final - hab neber heard such sonics before...totally sucked into the music....relaxed 100% no matter what genre, eben though the details retrieved is the maximum eber heard. You never want to analyze the music with Torreys Final. More balanced, transparent and extremely huge stage, bass to die for (better than TorreysB)...toe tapping non-stop, the music are pieced so nicely there is simply no gap between notes...but somehow this leads to less emotional feel....

This is the dilemma I am in right now...

Ok ok all brolers....this is a silly mistake....I keep wondering what went wrong, then today I run through my system, and found my Sound Application TZ1 conditioner analog piece sitting on 2 footers, not 4. The weight of the Ansuz DTC power cords really pushing it to one side.

I slotted post-it pads underneath, and make sure the DTC footers are 'eating' nicely eben with some slant (more post-it) at the higher slant.

This morning spent 3 hours testing the Directstream for the analog attenuation function. Specifically activating it would have 20db noise attenuation. The analog volume output will also be lowered too....even though I still set the Directstream output volume to 100. The analog preamp volume was subsequently almost doubled to 45-55. Although I tried before previously it did not work out for me...this time the effect is better than without analog noise attenuation. Probably because of better DTC cables and ASI preamp that is up to the task....very happy today. Brolers with Directstream might want to give it a try :)

Post by: mikey8811 on August 06, 2016, 22:42


I am not commenting on Torreys vs Yale.

I just compared it the Torreys upgrade to a Cary DAC 200ts. I found Torreys a little sibilant and I agree with the lean description. Don’t get me wrong, I liked it in its own way – there was more openness, inner detail and microdynamics were better, especially with strings and the way instrumental sounds decayed. There was also sweetness in the upper mids that gave some vocals a pleasing lilting quality. However, I missed the full bodied sound of the Cary and the slam it had.

Was Yale a fuller sound? I tried it briefly before upgrading to Torreys but also had the impression of sibilance and a relative lack of body vis-a-vis the Cary

Does it get better with further break in with regards to having a more full bodied sound?
Title: Re: PS Audio DirectStream DAC
Post by: Doggie Howser on August 07, 2016, 00:02
I don't find Torreys sibilant at all. But you could be comparing the tube vs solid state sound. never a good way to compare IMHO

Post by: durianlover88 on August 07, 2016, 17:45
Broler Mikey...run-in for Directstream is 2 stages: 1st one at 500 hrs, 2nd one at 800 hrs. Gonna be patient there....

Go back to the top of this page....something might be miss-adjusted somewhere in the chain...footers, powercords, distributors etc...tubes imho are colored (shield on)...so the reason I switched to solid state after coming a long way from ARC Annie 40 preamp, Ref 150 and tubed CDP. Agree with DH is not a good comparison, unless have a means to compare to the real live performance and see which more accurate. My DAC search ended with the DS on Torreys Final Final.

Title: Re: PS Audio DirectStream DAC
Post by: mikey8811 on August 08, 2016, 02:27
Hi DL88

I thought it may be the tubes at first but it isn't. The Cary DAC has a user selectable tube or solid state output. I switched to solid state and true enough it was also a full bodied sound. It uses an AK EQ4490 chip which is designed to have a full bodied presentation.

I have also seen comments on the DS board over at PS Audio where people have said:

my experience is, that in the not completely unusual case, the DS generally has not enough midrange richness for some tastes in some systems:

if you have a chance to compensate this differently, the newer firmware is always clearly better than the previous ones and their difference in richness is tiny and irrelevant in comparison.

But other than bass and treble matters , midrange issues are much harder to fix if not matching to one’s taste from the source.

The DS is from a friend who has had it since November 2015 and he tells me it is well broken in, even though it has been in storage for the last month, so I do not believe that break in is the factor.

Post by: durianlover88 on August 08, 2016, 07:42
Hi bro Mikey, sharing my experience here, so don't be offended.

I recently sold my Marantz 8802A, also based on AKM4490, caused I felt based on stereo performance (after feeding it with 4m DTC Diamond power cord, 2m DTC Diamond interconnects, DTC footers, RGC24, plus SA conditioner, on Pure Direct) - still too far off from the SQ of Directstream (midrange included). Hence I sold it off and reverted back to 2 channels even for HT.

IMHO, tube midrange is to 'die for', but unfortunately 'not accurate' (Shield On)

I fondly remember the times playing with Jadis JA80 Anniversary, Conrad Johnson GAT and ART Monos, Annie 40, I still like their midrange magic, and going from tube back to solid state is probably the hardest thing to do for any audiophile. It is also not easy to find SS equipments that 'beat' tube behemoths.

'Accurate' in my understanding means less ajinomoto added to original music intent and as close to live as possible. Tube midrange magic/fullness however seems to go against this (Shield On).

I am still keeping my LH Labs Geek Pulse Infinity Signature Edition. It has a slightly 'thicker' midrange compared to Directstream but still very acceptable for me with its overall sonic attributes (not 'overboard' to the tube presentation). But that would be the furthest I could go. Even EMMLabs DAC2X which I used to own, has this 'full midrange' phenomenon.

Just my own sharing....so don't have to agree. Mostly importantly you must enjoy the music. If Directstream is not suitable then stick to what you would normally prefer :)
Title: Re: PS Audio DirectStream DAC
Post by: mikey8811 on August 08, 2016, 15:16
Hi DL88

No offense taken. Your feedback is much appreciated. It comes down to subjective preference.

Like I say, I do like the openness, inner detail, spaciousness, soundstaging, decay, filigree on massed strings and the lilting quality on female vocals (when it doesn't tend to sibilance) on the DS. I just miss that midrange bloom that I like, real or not.

You used to have my dream system - the CJ GAT and ART Monos ;)

Did you ever try a Lampizator or TotalDac?
Title: Re: PS Audio DirectStream DAC
Post by: durianlover88 on August 08, 2016, 15:48
No I haben heard sibilance yet on DS.

No experience with lampizator or TotalDAC.
Can check with Murphy33 (lampizator golden gate), and composition/Wymun for TotalDAC :)
Title: Re: PS Audio DirectStream DAC
Post by: mikey8811 on August 12, 2016, 21:59
OK I’ve tried it further now.

Maybe it was a settling in issue but I think the main problem is the low gain. I cranked my preamp volume up to past 12 o ‘clock on most music (with other sources, 9 o’ clock is plenty loud and going beyond is deafening) and found it more likeable – it still hasn’t got that midrange richness or bloom in spades but the added volume seems to have filled that out some and there are more saturated tone colours. Fingers crossed it gets better and doesn’t go worse.

Does anyone else find the low gain to be an issue? I am using the balanced outputs with an additional 6 dB of gain, have the volume output set to 100 and under Settings it is on the high volume one. I fiddled around with the filter button on the remote as I read somewhere that is an attenuator of sorts but with it engaged and volume output set to 100, it just went even softer. I would have to turn my preamp up to crazy levels unless I am doing something wrong. The other thing I found was now increasing the preamp volume control did very little incrementally when before with other sources just a small increase would boost the volume quite a bit.

Is this normal or have I got a defective unit?

Thanks
Title: Re: PS Audio DirectStream DAC
Post by: fgchong on August 13, 2016, 08:55
mikey8811, just for your reference, I need to crank up the volume quite a bit to compensate with the difference in loudness output against the ARC CD09 (5-20 on a 100 scale) but I do the same on a smaller scale for both my turntables.  Would suggest you check with Paul in the PS Audio forum.

IMO, there is a huge gap with the PS audio and the ARC in term of overall sonic performance with the gap widen after replacing the stock 6550 tube to GEC KT88 tubes in the ARC, it's is just not tube vs solid state.  Probably I have not optimise the capabilities of the PS audio and still trying to do so.

Generally the Directstream DAC analog output is lower than other makes.
My ASI Liveline preamp is usually at 17-32 level at the DS DAC High (un-attenuated) level, but I have since engaged the noise attenuator (-20db noise reduction), which also reduces the analog volume by 20db (volume on DS setting still at 100). My analog preamp is now playing at 38-55. The sonic rewards are very big, especially if the preamp quality is good.

I had tried this at A&L showroom, with the new PS Audio Preamp....the moment I played it this way (volume 35 going to 70)....everyone jaws simply fell to the ground :)

Thanks for the replies.

DL88, what is the volume scale on your ASI?

I am already going to 12 o' clock on my preamp with high level output set at 100 on the DS. If I put the attenuator on I may have to turn it up close to full which is scary.

My ASI Liveline preamp can go until 64.

Directstream owners, pls listen up...try the Singxer-SU1 connecting to the I2S input.
I knew fgchong did this, I had the unit for a week but only managed to hook up the optimized fashion by today. In between, I went for 2 operations and now back at home resting.

This is taking the USB output from Aurender W20, via Ansuz Diamond USB cable, connected into Singxer-SU1 USB input. The 5V USB power is drawn separately from Uptone Audio JS-2 LPSU, as outputting 5V from W20 is not good, probably due to insufficient to power the input side circuits of Singxer.

From Singxer, connect I2S output via Audioquest Diamond HDMI 2m cable to one of the I2S input. Singxer is of-course connected by Ansuz Diamond DTC 2m power cord, sitting on 4xAnsuz DTC footers, grounded by RGC-24 conditioner. The fuse is changed to one aftermarket fuse, not the F250mA, but T1A (after confirming with James).

I thought no more veils can be removed...but a further few layers are stripped. OMG!!!

Some possible reasons for the sonic upgrade:
1) New USB XMOS receiver chip with better horsepower
2) Galvanic Isolation
3) Femto clock reclocking
4) Clean I2S conversion (not going into the older XMOS chip in DAC), but not losing 2xDSD playback. Using SPDIF/AES can only play 1xDSD via DOP I think.

A big revelation, letting the unit run in currently.
I will next test its Word Clock output to W20 :)

I tried Firmware 1.2.1. At the same time I added a Cardas Clear Beyond Power cord to my power amp.

The result was added weight and midrange richness. Slight but enough to make it musical for me. The openness and space between instruments diminished somewhat but I preferred what I heard overall.

I am reverting to Torreys again to try it out just in case it is the contribution of the Cardas Clear Beyond that is giving the sound the much needed midrange bump rather than the firmware. Hopefully, I can get both the midrange richness and the airiness back again but somehow am skeptical.

From what I have read here and elsewhere, 1.2.1 is the firmware with the “best” midrange richness. I understand that both Pikes Peak and Yale are inferior to Torreys as far as this midrange attribute is concerned so it is a waste of time to try those. Is this correct?

Seriously, with the Singxer SU-1 in place now (from USB input to I2S), there are so much natural fluidity to the vocals and instruments...it feels like real person singing there...there is also tube-like improvement to the SQ but not heavily overdosed like typical tube equipments...I don't know is that what Mikey is looking for. I don't have any tube equipment within my hifi rig. You can come my place for a listen now I on medical leave during daytime weekdays (evening cannot), we can discuss.

It would seem the more accurate we can feed the source information into Directstream, the more accurate it can portray the magic in the music :)

Thanks for the offer DL but I am not in Singapore.

Do you think it is the I2S connction that makes such a big difference? If so, why not go for a transport like the Sonore Signature Rendu or Bridge 2 that outputs I2S?
Title: Re: PS Audio DirectStream DAC
Post by: durianlover88 on August 26, 2016, 13:59
Almost pulled trigger on Sonore Signature Rendu, but it has only network input, decided NAS not for me based on previous experience....disk failures and eberything. Plus the price seems really high.

Bridge 2 I did test in my system, but not to my taste (not sure it is because it is new, yet run in), plus it can only do 1xDSD.

My source is Aurender W20, so USB output for 2xDSD. The Singxer is USB in, I2S out without compromising 2xDSD. It is rare a MIC item can do such wonders, but rave reviews are everywhere in Head-Fi and other forums, so glad it did not disappoint :)

Title: Re: PS Audio DirectStream DAC
Post by: durianlover88 on August 26, 2016, 14:19
It is not similar to USB input, or any other input. It seems to have everything, but stop short at maximizing all attributes (maybe my expectations too high). It is like a computer source maxed out kind of sonics. It sounds a bit colder than the main units inputs. It is however much better than the Bridge 1 I used to have with Perfectwave DAC.

Post by: durianlover88 on September 05, 2016, 09:53
As you saw at my place, the Directstream DAC takes centerstage for both Stereo and HT.

The 'lousy' tracks we deemed are actually mostly ok.
Many test tracks I played actually will break a lot of systems.
Many will hear sibilance, distortions, breaking sonics, etc.
This is mainly because the systems are yet optimized/bottlenecks yet addressed.
In digital, the areas to addressed are more vast. Eg. Power, footers, cables, EMI/RFI, component features/clocking, etc.
When properly addressed, most will find 'lousy' tracks enjoyable again.

Garbage in, Garbage out applies when the processing system is optimized.
Good in, Garbage out also applies when the processing system is not optimized.

Versus CDP, if CDP is better built/optimized than the digital playback, sure it will sound better. Similarly digital playback system better optimized than CDP will have the reverse results.

Despite I use W20, it has its own weakness as well.

I am now looking forward to the next DS firmware release :)

Hi guys with the Singxer SU-1. You really should try using the AES/XLR output of the Singxer to the AES/XLR input of the Directstream. A friend and I did some comparisons of I2S/HDMI vs AES/XLR from Singxer to the Directstream, and the AES/XLR sounds smoother than the I2S/HDMI which sounds a little harsh sometimes. Both XLR and HDMI were using similar grade DH Labs Silversonic 1m cables.

(Audio)
The Directstream has the Bridge v1 installed, which was so-so. We preferred USB (with Uptone USB Regen) to the DS Bridge v1.
Adding the Uptone USB Regen brought a big improvement (vs direct USB).
Adding a high quality LPS to the Uptone USB Regen brought an even bigger improvement.
Adding the Singxer SU-1 again brought it to another level - the Singxer SU-1 is definitely way better than the built-in USB - it sounds a lot more detailed.

Since the Singxer SU-1 has multiple digital outputs, we compared the different connection options of AES/XLR vs I2S/HDMI. The I2S connection sounded a little harsh on the highs, and the AES connection sounded more relaxed. I2S sounded a little brighter, but overall we prefer the XLR for now. The I2S/HDMI cable used was new though, so maybe it will improve with run-in. The difference between I2S and XLR was small but noticeable.

This system uses an MBL preamp with MBL mono-blocks powering YG Anat Reference speakers. AC Power is supplied using a combination of several PS Audio Powerplants (P300s for sources + PP Premieres for amps).

With the same source (a 256GB thumb-drive), this is what I tried so far and the results (with my system and in my opinion) as in descending order:

1.Mac mini-Singxer-CD09 via AES
2.Mac Air-Singxer-DS via I2S
3.Mac Air-Singxer-DS via AES
4.Mac mini-MF V-link192-CD09 via AES
5.Mac mini-CD09 via USB
6.Mac Air-MF V-link192-DS via AES
7.Mac Air-DS via USB

*Did not installed bridge on the DS and have no intention, awaiting new transport from PS Audio ;)

Interesting.... somehow that doesn’t surprise me actually. I think it’s was mistake for PS-Audio to carry I2S over HDMI cable; consumer-grade HDMI silicon, synchronous signal with no error correction, over piss-poor skinny conductors… I’d say thats a recipe for a rather harsh sonics ;D (although I suppose there aren’t too many other standard interface options for inter-device connect).

I saw the Beta Transport when I visited PS Audio a few months back. It was using the now discontinued BDP-101 base unit (drive and processor) but with a PS Audio developed board with 3 I2S outputs on it L/R C/Sub LS/RS as I was told (but don't quite me) for 5.1 SACD support. Im not sure if BRAudio was also to be supported, but there was no video support.

Extended high-frequency response
Extended low-frequency response
Cleaner, simpler filter design
Blacker backgrounds
Increased depth of soundstage
MQA ready (with Bridge II free upgrade)
Tidal ready (with Bridge II free upgrade and MConnect app)
Maximum volume set level (so it won’t get too loud)
Split final upsampling filter to eliminate it in the DSD path
Lessened noise on DSD -> PCM or PCM -> DSD transitions.

I've heard it.

Initial impressions are good.

It has more midrange richness which I like above all.

But there is also more of everything else - more highs, more bass and space between instruments.

I am not so used to the more highs and bass - it seems larger than life and maybe overwhelming.
The presence factor is blown up large and to me less refined. There is also less sweetness and delicacy in vocals and a more chesty sound. But that is in conjunction with some Cardas Clear Beyond interconnects and power cord thrown into the mix.

The blokes on the PS forum lurve it - they say it is pretty much all I say (without the less refined and abssence of sweetness) with smoothness to boot.

I'll let it settle down a bit.

I seem to remember you like resolution and detail so my guess is you may like it. But don't jump straight back into it since you just got out.
Title: Re: PS Audio DirectStream DAC
Post by: fgchong on June 09, 2017, 20:49
Installed the new firmware and is listening for almost 2 hours, I share Mikey8811's comments on the richness in midrange  and have more bass but the highs seems be be the same.  There is also better clarify and better separation of the music.  I need to crank up my Ref-10 dial to maintain the same listening volume.  Overall I see some significant improvement over the Torrey but not night and day. 

When compared to my CD09 (as a DAC), though the gap is closer but is still a distance away in term of overall music presentation. Maybe I am biased as I am more a tube guy and also the CD09 has an upgraded software and also the tubes used are NOS tubes

Bro DL88,
Torrey Final seems more docile in comparison but with pros & cons (based on my set-up).

The rave of it being quieter is true resulting to better imaging, clarity & fuller vocals and instruments tone. A tad loss of overall airiness. Will post more after more extended listening

It may suit certain people with DS DAC depending on their type of music preference. YVMV :) :) :)

I was holding back upgrading my personal unit because I was having a cold.

I did find the differences much more apparent with some Queen tracks I was testing at work.

Back home, I resisted - listening to Torreys as much as I could to get a baseline. But couldn't resist upgrading to Huron in the end.

Even with the cold, there was some noticeable differences though perhaps not as much as when I was using Queen. It feels like there is more I am hearing again. Could it be because of the lower noise floor? There also seemed to be an improvement in the soundstage width - just wider and more expansive. It wasn't as noticeable with slower paced music.
Title: Re: PS Audio DirectStream DAC
Post by: Doggie Howser on June 11, 2017, 15:59
So after some much needed bed rest, I fired up the system up again.

Left the BHK monos and preamp on standby - the tubes are left unpowered but the solid state is kept warm.

And when I came back today they were ready to fire up.

When I was testing Huron initially, I was using lower listening levels because of the late hour.

It's one of the things that I've loved about the full PS Audio stack - just so much transparency even at low listening levels.

But this evening I was able to pump up the volume.

And wow. The difference Huron made was just much more noticeable. I've always maintained that the full PS Audio stack made my bad recordings somehow more listenable. Had a customer come in yesterday to test the theory. He brought some Marilyn Manson and came to the same conclusion

With Huron, it seems that cranking up the volume was no longer as grating on those bad masterings. I just love being able to listen to my favourite tracks and not worry about getting my ears zinged.

Also more noticeable was how in some recordings there's a deliberate panning of say drums from left to right and back in consecutive drum beats or the same with vocals - the Huron made these sound far more apparent.

From headfi watts up:-

"While following the PSAudio DirectStream threads regarding their regular DAC firmware updates, i was surprised that several final release candidates were auditioned prior to each release - and the code was mostly functionally identical .. with only changes in signal flow, timing, parallel -vs- serial, compilation switches, etc. Yet, each variant sounded 'different' - and the final release determination was based on a compromise. What this is telling me is that we are so near the bleeding edge of silicon switching noise and ground plane disturbances affecting even a 'perfect' DAC algorithm."

My personal opinion is that this is somewhat unique to PS Audio because Ted has only been playing around with FPGAs since the inception of the DirectStream DAC - he’s a newbie. Other DAC vendors have been using FPGAs for decades and have a much better handle on these types of issues.  In fact, with current FPGA tools, even system noise characteristics can be simulated with the end results being very close in actual implementation, no need to “trial & error”. PS Audio are really NOT at the “bleeding edge” by any stretch of the imagination :)

Everything that PS Audio learns, they like to pretend they’re the first and no one else has learnt or done before - it’s all BS marketing from Paul McGowan (not from Ted). If you read the PS Audio forums, it’s filled with fan boys who lap it all up because they just don’t know any better. ;D

And yet Chord nor Playback nor EMM have done as comprehensive a series of upgrades as Ted.

Don't think Ted is a newbie when it comes to programming.

Plus it is clear that while EMM resorted to forcing a hardware upgrade from XDS1 to XDS1v2, the DS DAC more than caught up with the v1 then the v2 in about a year of its release.

I am in the mkt for a simple dac for my secondary listening. Ps ds seems to be a value buy.
 
Question for all: So all these updates, are they more of.like changes in dsp settings (freq bandwidth,gain,timing). All these will affect tonality soundstage width/height/depth and darkness/brightness

I really hate the idea of after doing it up to a sound i like and then it changes again.

Did a First Class Honours project for my university computer engineering degree, via optimizing filter functions within FPGA....maybe I did this decades ago, and assume Ted started later (but he older than me so I neber know, need to ask him when he started programming FPGA) - in this case I stagnant for decades, but he producing firmware after firmware of optimization - so start early really means better?

When multitude of FPGA logic functions come together (20x upsampling, using 3 clocks instead of 6, and loads of other functions), the ability and sophistication of compiler to compile FPGA optimizations becomes key. Of course if Optimisation can be done before compiling will be best. So I understand why there are multiple versions with differing SQ and require Arnie to audit (Ted did not get to listen until the 'best' version is chosen).

Of course if one does just one simplistic set of filter logic functions, no optimization, just one compile and that's it, then so be it. Does not mean what PS Audio did is wrong. The reward is in the SQ improvement heard...only this counts.

The Optimisation Ted does is mainly in area of noise reduction. All parameters should only improve, not cause change in tonality, etc....at least this what I noticed with previous version upgrades....I still blame myself for not having the option of hearing Huron...

Yup! It flows from the top, Paul  ;)


The thing is Ted is about optimizing the code and not about DSP per se.

I get what you’re saying, here’s my point though; others have already gone through this iterative process of objective and subjective improvements to their FPGA code over decades… Just because they’ve already pushed their platforms to the limits before its released doesn’t automatically imply PS Audio is doing a better job when they expose Customers to this process of optimising the code while Ted learns, and fanboys somehow think its great (they’ve been exposed to what is effectively being beta testers over years)

Ted admitted himself that he only got into this since AES 2000… EMM’s Ed Meitner has been doing audio hardware design since 1972! PBD’s Andreas Koch, since 1982! Do you really think they don’t know how to optimise FPGA performance? PS Audio is not doing anything new that hasn’t already been done before, the only credit they deserve is offering platforms at a relatively mass-market price point. Even on non-FPGA based solutions; PS Audio likes to poo-poo ESS Technology…  but watch ESS’ CTO Martin Mallison’s RMAF 2011 video on Sigma-Delta DACs (http://www.youtube.com/watch?v=8Mn5PrnZV-k) for example, you’ll gain a whole new level of respect (and realise why they’re the industry market leader).

It pisses me off when Paul PcGowan and his band of ignorant fanboys dis giants who’ve come before. I feel compelled to piss in their pond but you know what they say, “Never underestimate the power of stupid people in large groups” (Singaporeans know this better than most others, I’d rather post here on X’Place instead ;D)

All I can say is - my DirectStream DAC is possibly the best bang for the buck gear I have ever gotten. It's the one that keeps upgrading itself - and IMHO has superseded my EMM/Playback Designs equivalents.

When EMM offered a 20xDSD upgrade, it was a completely new box.

And as for Paul, I have customers who met him at different hifi shows and all of them are always amazed at how down to earth he is. If he is guilty of anything - it tends to be over-exuberance :) but that's something I am guilty of as well.

... It's the one that keeps upgrading itself ...

And as for Paul, I have customers who met him ...

…Because it wasn’t at the best it could be to begin with. Here’s just one quote that objectively demonstrates this (Stereophile);

Quote
Things didn't look so good, however, when I performed a wider-band spectral analysis with the PS Audio processing dithered data representing a 1kHz tone at –90dBFS with 16-bit (fig.6, cyan and magenta traces) and 24-bit data (blue, red). With 16-bit data, the noise floor is dominated by the dither used to encode the signal, though a trace of second-harmonic distortion is visible. But when the bit depth was increased to 24, which was correctly indicated on the front-panel display, the noise floor dropped at most by 5dB, suggesting that the DirectStream DAC has only about 17 bits of resolution.

So, you got a lesser platform, which has been slowly incrementally improved over time, period. If you're happy with that, so be it, I’m sure I'm not going to convince any fans ;D

As for Paul, I’m sure he’s a nice in person, that not the point, his own online posts stretching the truth and feigning ignorance, speaks for itself (no need for 3rd party hearsay).

Good thing I don't listen to test tones because the Playback was one of the DACs that hooked me onto DSD.

When I changed the bit depth of the incoming data from 16 to 24 with a dithered tone at –90dBFS, the noise floor dropped by 23dB (fig.5), implying resolution close to 20 bits, which is state-of-the-art DAC performance.

In other news, after getting my weekend chores of lawn mowing down, I sit down and have a listen to Bocelli's Amore from HDTracks 24/96.

It's always soothing and cathartic and this time, I'm amazed at how some softer strings which are normally masked by the louder lower notes of another string instrument coming across. Something I've not heard previously on the EMM or Playback.

I think the combination of Arnie and Bascom along with Ted is why we are getting these improvements.

And I don't see it as a sign of lack of maturity. Merely a commitment to improve. Rather than sell us a whole new box. Which would probably benefit their bottom line better. After all only PS Audio fanboys buy PS Audio gear. and we'd buy it all over again, no?

You’ll have to excuse me if I trust John Atkinson’s actual measurements (coupled with my own listening of the DirectStream DAC) more then the purely subjective ramblings of PS Audio fanboys. As for going “overboard condemning a 6K USD DAC” - making comments about the maturity of Ted’s FPGA code, and Paul’s hyperbole B.S does not mean I’m “condemning” the DAC… you took it that way, that’s your pasal ;) ... FWIW, I do think the DS DAC is an ok platform for price/feature-performance and I’ve commented so a few times before. As for coming across as condescending… if you don’t like to be corrected, then when referring to specs, please post accurately, and preferably with source(s). Simple  ;D

And why the need to bring up Chord DAVE out-of-context in this PS Audio thread?! But since you brought it up, regarding your comment about “16-bit digital accuracy is what Rob Watts said”… I’m pretty sure you’ve misunderstood Rob’s discussion on head-fi about needing 1M taps in order to perfectly reproduce a normalised sinc function for better than 16-bit sample… That does not equate to the actual resolution that DAVE’s capable of, which is close to 21-bits as mentioned in JA’s, and Rob’s own measurements (without M-Scaler).

Took me a zillion tries - OK I exaggerated. I stopped counting after the 10th try.
 
But here's another possible cause for the firmware not loading - the USB stick. I tried the Yale downgrade too. Didn't work. Also tried letting the power supply discharge for 5 minutes. Nada. Reformatted in FAT32 or FAT16. No dice.

I noticed this a few months ago when I needed to copy files for the SACD rip on the Oppo 103.

One of my thumb drives just refused to work. Switching to another worked just fine.

On a hunch, I changed the one I was using.

Tada. Worked fine.

And here's the kicker.
 
Huron on DSJ is a lot closer to Huron on the DS vs Torrey on both. No idea what Ted did but it's awesome!!

I no longer feel the DSJ is a poor cousin. It's now making the Sr a little embarrassed.

Also is the Stereophile review of the original DS in 2014? As durian and I have stated before. The DS in that form was close to the EMM and Playback but not quite surpassing them... it took them a few more goes before Ted surpassed them.

Stereophile measured 3 firmware versions…

https://www.stereophile.com/content/ps-audio-perfectwave-directstream-da-processor-measurements (original v.1.1.4)

https://www.stereophile.com/content/new-firmware-measurements (Yale v.1.2.1)

https://www.stereophile.com/content/ps-audio-perfectwave-directstream-da-processor-more-torreys  (Torreys v.1.whatever ;D)

Bottom line; while noise floor and low-level distortion were improved, actual measured resolution did not improve much between versions beyond that 17 bits originally measured. It’d be interesting to see if the new version measures any different on JA’s bench.

As for EMM and Playback Design, neither of their DACs were ever formally reviewed in Stereophile, so, no measurements to compare, everything about them in comparison to the DS DAC is subjective at best. I’ll take your word for it that you found the DS DAC bettered the PBD; is it possible (or surprising at all?) for a newer platform to sound better than a 5-year older flagship? Of course. Word on the street is that EMM’s latest DA2 sets a new benchmark. I wouldn’t be surprised if PBD’s new Dream series is also a stellar performer ;)

Got lah

Increasing the bit depth to 24 or playing back DSD data usually drops the noise floor low enough to reveal the player's or processor's own noise floor. (For an example of superb performance with this test, see the measurements accompanying the review of the Bryston BDA-1 processor elsewhere in this issue.) But to my surprise, given the Playback Designs player's pedigree, both 24-bit PCM and DSD data gave a noise floor that was only 3dB lower than with CD data (fig.3, bottom two pairs of traces). And again, the left channel was noisier than the right—so much so that the left channel with DSD and 24-bit data was noisier than the right channel with CD data. Repeating the spectral analysis using an FFT technique confirmed the MPS-5's disappointing performance (fig.4), with the noise almost high enough in level to obscure a dithered tone at –120dBFS. In addition, the noise floor for SACD playback was disturbed by some low-level enharmonic spikes (fig.5).

Between both durian and I, we have 4 x EMM and Playback DACs. When I got the PS Audio, I wasn't expecting it to better the EMM or Playback. The Playback was a great all in one DAC and SACD player so the DS DAC was to augment my other system with the EMM XDS1 for DSD computer audio. And it didn't. But it did with Pikes.

Interesting from the measurement report.

I had to agree with Bob Deutsch. Even without greater measured resolution, it did indeed sound as if there was more resolution. I switched back between Torreys and Yale and back to Torreys and the impression of greater resolution with Torreys persisted. A paradox.

Oh right… PBD’s CD Player (reviewed) has an identical DAC stage to their dedicated MPD-5 DAC (not reviewed).

But PDB’s measurement issues notwithstanding, how come you’re conveniently ignoring the fact that Playback Design’s MPS/MPD platforms are actually   8 6 years older than PS Audio’s DirectStream DAC! :P PDB introduced MPS-5 in 2008… PS-Audio introduced DS DAC in 2014.   8 6 years is literally 4 generations in the tech space…

Should the measured performance matching/surpassing surprise anyone?

I don’t know why JA would say it’s paradoxical… it’s not rocket-science; surely improved noise floor and lower distortion will contribute to a perceived improvement in resolution because small sonic details will be better revealed!… So of course resolution will seem like it’s improved without actually having to! Nothing magical going on… (just my personal opinion of course, no need for anyone to get all upset… kekekek ;D).

For the record the Playback was released in 2008.

And the DirectStream DAC is almost 4 years old. It was compared to an XDS1 which was released in 2010. And the two box TSDX/DAC2X from 2012. It's still doing well against modern DACs even getting a Product of the Year award two years later.

I had that happen before with the DSJ with Torreys

It was also showing Roon support on DSJ as beta or something.

http://www.psaudio.com/forum/directstream-all-about-it/fpga-improvements-in-redcloud/page-4/#p81451 (http://www.psaudio.com/forum/directstream-all-about-it/fpga-improvements-in-redcloud/page-4/#p81451)

What's everyone take on it?  @AndrewC

Well, Ted's throwing a bit of smoke around  ;D... While his arguments against JA’s measurement technique is interesting... JA’s method of estimating the DAC’s resolving power is based on fundamentals; the DAC’s resolution, in quantisation bits (Q), is directly related to the signal-to-noise-ratio (SNR) and hence the noise floor. The equation is; SNR = 20Log10(2Q)...  So, JA can estimate the resolving power in bits by looking at the difference in the noise floor levels between playing a 1kHz 16bit signal and 24bit signal.

Ted seems to be suggesting this is not a good way to measure... and gave the example of dither that “increases resolution at the expense of raising the noise floor” (thus suggesting noise floor is not a good measure)... But, to be quite pedantic, dither doesn’t actually increase resolution, it helps to reduce quantisation errors, thus making noise more benign and the original signal more perceptible.

Even for argument sake, let’s say Ted is completely correct... but JA is still measuring ALL DACs in the exactly the same way! So when recently measured DACs like Ayre’s QX-5 (https://www.stereophile.com/content/ayre-acoustics-qx-5-twenty-da-processor-measurements), or Benchmark’s DAC3 HGC (https://www.stereophile.com/content/benchmark-dac3-hgc-da-preamplifier-headphone-amplifier-measurements) demonstrates >20bits of resolution, while the exact same measurement technique on the PS-Audio DS-DAC reveals only 17bits of resolution, then objectively speaking, the DS-DAC is not in the same league as those others (at least as far as resolving bits is concerned).

In any case, I guess for the sake of PS-Audio fanboy’ peace of mind, maybe JA will at some point re-re-re-measure the DirectStream DAC... its already been re-measured twice before without significant improvements to the actual resolution... maybe 3rd time lucky? ;D

The Playback measurement didn’t do so well either. Maybe that’s just a function of measuring a DSD DAC with a PCM type analyser

Nah... not likely. JA's measuring the analog output, it’s easy to see the true effects of DSD on non-FFT frequency spectrum plots of the 1kHz sample signal, like the graph below, though he doesn’t often include them in reviews like he used to before... but you’ll notice even the FFTs included are cut off at 10kHz where DSD ultrasonics should have no effect (unless the DAC is crappy ;D)

ps: There's something else going on with PBD's MSP-5 design... Andreas hints at it in the Manufacturer's comment response to the MSP-5 review, but he certainly doesn't claim JA's measuring wrongly ;)

Nope Andreas didn’t. He just said it sounded better even with worse measurements.

Most of the measurement results are generally to be expected from the way they were measured. What differentiates the D/A converter inside the MPS-5 from other, more conventional converters is that it uses all custom algorithms and discrete components that were not designed following classic theories and practices.

So does Ayre, which is PCM-based design. Doesn't mean much, all it does is switch filters for full-scale measurements.

True… not everything that can be heard can be measured… but, many things can be measured and can be co-related to whats heard - I’m sure you know well that Rob Watts is one of the biggest proponents of measurements and listening correlation! Here’s a perfect example from his first blog post on Head-Fi;

Quote

Don't listen with gross errors. This is perhaps only appropriate for a design process - but it is pointless doing listening tests when there are measurable problems. My rule of thumb is if I can measure it, and it is signal dependent error, then its audible. You must get the design functioning correctly and fully tested before doing listening tests. 


In that same post he goes on to show why it’s important to have low noise-floor… which the DS-DAC fairs poorly. In fact, his whole post is well worth reading; https://www.head-fi.org/threads/watts-up.800264/#post-12457933 (https://www.head-fi.org/threads/watts-up.800264/#post-12457933)

I’ve heard the DS-DAC for myself of course, and to be quite honest, the Stereophile’s measurements don’t surprise me one bit (pun intended ;) )… sonically it was never a giant-killer (contrary to what some would like to imagine), and it’s well surpassed now.  In any case, I’m sure I’m not going to convince any fanboys, but I can’t helping commenting either (PG’s constant marketing-spin-B.S spurs me on ;D )

It’s been a while now but I did consider dcs before i ended up with the EMM which was my yardstick for a long time.

I honestly believe the DS does so many things right that I can’t figure out why they measure wrong.

Each update leading to Huron was a step up from the previous in terms of blackness of background and the way all the background instruments just become more delineated and spaced out in the soundstage.

The initial transient of instruments.

All the things I look for in my system.

My personal view is that the initial release of DS was not too optimized.  It's the first time Ted is doing something like this and I'm sure the code was very brute force approach.  In the corresponding release when we read the release notes, you see Ted rewriting certain section of the codes for optimization 

For the coming release looks more like a "bug fix" for the noise that DS is generating hopefully this will fix the "17 bit" resolution issue.

Yup, totally agree with that view.

That said, on the 17bits resolution “issue”... (other than peace of mind) it’s probably not an issue as long as… (a) people don’t sonically compare the DS-DAC against something else better.. or (b) quite possibly, they’re using an Amplifier that has an even worse SNR performance (less than 102dB, the equivalent to 17 bits). In other words, in isolation, most people wouldn’t perceive any deficiency with their DS-DAC, and/or their Amp is the bottleneck anyway! ;D

Ted has his work cut out for him, theres both Digital stage noise and Analog stage noise to take care of... the FPGA re-coding work can only addresses the former… the latter would need a hardware upgrade ;)

I’ve tried the PS Audio DAC on Classe, Chord Electronics, Plinius and Audio Research Electronics.

I’m not convinced the amps are a bottle neck.

In fact on my BHK amps with a linear PSU modded Mac Mini, I preferred the Chord DAVE to the DS DAC when connecting over USB.

But with Roon and the DS Transport particularly with SACDs I ended up preferring the PS Audio.

Neither am I actually ;D… Not totally convinced anyway, it’s not as black and white as might be expected from a technical perspective.  My Wavac monoblocks have only about 95dB SNR, yet with high-rez playback I can hear deep into the music far better than via many of my previous solid-state Amps with significantly better SNR specs.

[Excuse my ignorance, just musing…so, fanboys needn’t get their panties in a twist ;D]

Scanning through the Ps-Audio forum on Redcloud, how is it that so many people seem to have bad/partial software update on the DS DAC and need repeated updates back and forth with older firmware to get the new firmware to install correctly?!?! ... 

Exemplified in this post;

(http://i67.tinypic.com/o8zzhs.jpg)

WTF… Don’t they have basic firmware checksums to verify integrity before and after an update?!?! ::)

Ted said it was because the SD card slot was designed for FAT16 and some cards formatted for FAT32 didn't work well. Best bet was to reformat card (preferably to FAT16) and then the files would load contiguously.

Thats not quite what I’m talking about though :P

How come the firmware can install incompletely on the DS DAC?! Seems like lots of people have somehow managed to partially install the firmware update, causing all sorts of ill-effects, and have to re-install the old and then the new firmware... as recommended by Ted himself!

I realise the DS-DAC’s firmware update is actually multiple files, but what kind of dodgy backward system allows partial installation of new firmware without full integrity checks both of the firmware files on the SD-card, and during installation on the platform? This whole DS-DAC firmware update process seems a bit mickey-mouse ;D

The NAD amps from 2017 all download individual files for each component of the upgrade.

Ditto with my Devialet.

And the explanation given to me is due to how the file is stored and loaded on SD cards.. Formatting them supposedly gives u a chance to write and load the data sequentially.

I noticed the DSJ actually displays a step called compiling - but that reads from USB. Might be why they moved from SD card n the Jr.

The SD card in the DS DAC is a remnant from the original PerfectWave DAC from almost a decade ago

And yet, I don’t see any one of those other platform’s users complaining about having to re-re-install firmware because of some dodgy partial install :P. Don’t you think it’s a problem that the DS-DAC’s operating system doesn’t check the integrity of firmware updates - users have to just "hope" that the install happens correctly?

(By the way, I’m not talking about SD-card vs. USB etc, thats just access to media holding the firmware, quite irrelevant to the point I’m trying to make above).

There is a difference in the way the DSJ updates vs the DSDAC.

The DS DAC is using a legacy SD card update system from the original PerfectWave DAC.

The USB on the DSJ seems to update differently because it is unhindered by the legacy SD card support carried over from a 10 year old architecture.

Both similar priced platforms. Both with firmware updates that contains multiple files. Both use SD-card based firmware updates;

Devialet (@2.14 onwards); Insert SD-Card, power-up… “Upgrading Software”… “Loading Firmware x.y.z”… “Upgrading DOS”… “Installing DOS”…. “Upgrade x.y.x Successful”.

PS Audio (@2.07 onwards); Insert SD-Card, power-up… <nothing but blinking power light> … The user has to then manually verify and guess whether the new firmware has been successful programmed into the machine.

I didn’t realise until now that PS Audio’s firmware upgrade process was so mickey-mouse ;D

The Devialet one wasn’t always so simple either.

The change came after the Expert 110/170 etc models were launched. Which was brand new hardware.

And in my initial upgrades pre v9 the updates sometimes didn’t go through either. You also needed to verify the changes afterwards by scrolling through the system menus.

I’ve had NAD firmware updates, Rotel firmware updates and KEF LS50 firmware updates bricking the devices. And that was just this year alone.

Actually the PS Audio one has been fairly easy. Insert card. Power off unit. Power on unit. Flashing led light. OS loads.

The DSJ One (being newer) is even more descriptive.

And this is the first one which failed me. Which as it turned out wasn’t an update failure - it’s just a bug I discovered. Which is being patched.

Is it formatted the right way?
Make sure the SD card is formatted in FAT or FAT16. We advice you to reformat it on the same computer you use to generate the files on.


And in my old manual of the Devialet 200

Quote
3 – Restart your Devialet by pressing and holding the power button for approximately 4 seconds. Until the word «reset» appears.
The control screen will display the loading progress of the update. This may take several minutes.
Once the process is finished, follow the instructions displayed on the control screen. Your Devialet is now up-to-date.
After updating, you can delete the files on the SD card, if you wish to use it for a new configuration.


I remember a few times, I couldnt even get the Reset to appear. Cant find the online manual for the older 240 now but I remember it required far more convoluted combinations of key presses and holding down of the power buttons.





YMMV.

[Hate to be quoting myself...  :P]

I only just realised that what I described above is a known phenomenon (related to dithering) known as Stochastic resonance (https://en.wikipedia.org/wiki/Stochastic_resonance);

Quote
Stochastic resonance (SR) is a phenomenon where a signal that is normally too weak to be detected by a sensor, can be boosted by adding white noise to the signal, which contains a wide spectrum of frequencies. The frequencies in the white noise corresponding to the original signal's frequencies will resonate with each other, amplifying the original signal while not amplifying the rest of the white noise (thereby increasing the signal-to-noise ratio which makes the original signal more prominent).

POF is pretty lame IMHO… only marginally better than TOSLink at a physical level and has limited bandwidth... certainly not worthy of a supposed flagship design. That said, seems the TSS is designed to a maximum of 11Mbps (DSD256) between boxes, so perhaps good enough?  IMHO it would have been far better to implement an industry standard SFP port and let end-customers decide whether they want to use an SFP module for Fibre, Glass/Plastic, MM/SM, or even Copper or Coax, etc., rather than this low-end POF Duplex connector;
