downside is needing to crimp the speaker cable

what speaker connectors are those?! look like lan sockets!
Title: Re: US$200 nuforce class D?

yeah they look like normal RJ45 connectors. wonder if LHS has crimpers

That's gonna severely limit the speaker cables u can use.... I wonder how many types of speaker cables can actually be crimped into a RJ-45 plug?

well, u can modify it abit by fixing the binding posts onto a plate and the back has 2 x RJ45 that can be plugged into those sockets! ;)

How does a RJ45 work? No +/- even?
Unless this is some sort of proprietary thing they made for their own speakers to be paired with this power amp?

Maybe we can plug it into an 8 port Ethernet Switch and do tri-wiring? Best sound will be from a GigaBit LAN switch?  <Sorry just kidding >   ;D

On a more serious note, I'm more curious about the USB connector in the middle though - wonder what's that for - does it have a built in DAC?

Anyway a very impressive looking unit and an equally impressive form factor.

Couldn't find any detail at its website.  I doubt it's as complicated as having a DAC in it.  Maybe just something that can utilise the USB 5V supply when use with PC. ;)

on 2nd look, don't think it's rj45.  Also doubt it's a proprietary connector.

Post entry note:  Extracted from audiocircle

Icon-1 will include two sets of speaker cables:
Set 1 = Cat 5 cable for connecting Icon-1 directly to S-1.
Set 2 = Cat 5 cable with banana connector for connecting Icon-1 to other speakers.

Yes I think a USB 5V Supply would be more like it, although it might have serious consequences if a PC is supplying all this power. Never mind that Nuforce might be a super efficient Class D.

Strange thing is that just a couple of weeks ago I was thinking of using this same USB connector type in making an offboard pre-reg +-12VPSU for my DIY UcD class D amp!

Lol! That's amazing.

UcD is definitely a very unique product though - I can't think of any other technology which is so easily accessible to DIY community and is also used by very high pedigree commercial manufacturers - the likes of Channel Islands and more recently the mighty Meridian. The 'U' in UcD is very apt - have tried it on ultra efficient Avante Garde Horns to power hungry 83dB conventional box speakers and everything in between - it really does deliver a very consistent performance across all.

I think in future we will see many more exciting Class D products like this cool new Nuforce - its just the beginning phase of this promising technology. It would be great to see a HT amp from Nuforce or any of the other players - - that would be cool.

For now, SC is doing a great job by maintaining a thread on Class D amps and keeping us all informed on all new products coming up. Hats off to him! :)

Got a Hypex amp modded with Blackgate caps. Love it!

Surprisingly, Quite Warm and natural sounding compared to some setups I've heard at Aldephi...including some setups whose speakers come with soft silk domes paired with solid-state amps.

Those blackgate caps are really quite something. Pity they are no longer available.

perhaps Bryston, too (http://blog.stereophile.com/ces2008/011008bryston) - the model number hints at the technology, imo


btw, the nuforce Icon-1 (http://blog.stereophile.com/ces2008/011008nuforce) seems to be 10W per channel

Hey! That's big news.

Yes it does seem that the new Bryston is based on Hypex UcD400. - some other indicators are use of a linear power supply - a Hypex UcD peculiarity, the amplifier module board is not very clearly visible but I think I saw a very distinguishing feature of Hypex UcD amps - that is termination of all connections on only one side of the circuit board. Bruno Putzeys, the designer of UcD strongly believes in it. Another commonality is  the bridged power rating of 800W into 8 Ohms - that's exactly what a UcD400 is specd to deliver in a bridged mode, although that could be a coincidence. Anyway I know who to confirm this with. Will revert later.

I'm not surprised that the NuForce is rated at 10W, the form factor and the type of connectors (the DC Supply Jack) indicated that it is targeted as a competition to low powered Tripath based mini amps such as the T-Amp etc.

If you look at front input selector switch the dots there correspond to 1, 2 & 3.

The 3 Indicator is printed below the USB connector on the back panel, 1 & 2 being phones and RCA respectively. I reckon it is indeed a USB input in that case.

A simple case of 'joining the dots' which we missed yesterday ? ;D

There is a USB DAC inside and you can just connect the USB cable to the Icon-1 and it will be recognized as a USB Audio DAC device by PC or MAC (haven't tried with MAC).  The Nuforce Class D IC is implemented with the same patented technology as our high-end amplifier.
We are still working on improving the sound of S-1.  We tried Icon-1 with a few desktop and bookshelf speakers at the end of CES (brought in from a distributor) and with a good speaker, it sounded very good.  S-1 that was demonstrated at CES has some implementation flaws due to the rush to get it to CES (waveguide was not shaped exactly to spec for example). Our challenge is to build a audiophile quality system at $399  :o

Both are in totally different class. One has been making PC casing and the other has been making high grade audiophile amps.
I'll pick the one with the credentials and history in making quality amps.

It sure looks nice.
15w at 4 ohm... does that means around 7.5w at 8 ohm?
But if it's my money, maybe I go for NuForce....
Title: Re: US$200 nuforce class D?
Post by: SiriuslyCold on January 16, 2008, 11:06
less - probably 6W @ 8Ohms - typical output for the Tripath 202x series amps

more than a few companies are using the Tripath with great success - Bel Canto used to before supply became an issue, Naim put a 50W version in their DVD receiver, some peopel here are using KingRex etc

DIYParadise and 41Hz even have kits for you to make them on your own so I would guess the Silverstone amp isn't going to be too shabby

It's nice to see manufacturers joining in the discussion, I for one feel much safer buying the product knowing that the manufacturer cares enough to share more details about the product.

Jason, would you be so kind as to explain the speaker connectors? Are those really RJ-45 connectors? This looks like a fantastic product, I hope the combo will be sold in Singapore.

Check out Nuforce Icon feedback thread (http://www.audiocircle.com/circles/index.php?topic=52636.0)

Post all your feedback of Icon here.

This comment came from a distributor who just received it yesterday:

I've been listening to this baby all afternoon, and it simply sounds incredible! Honest!
Compared to the Trends & Kingrex stuff, the Icon walks all over them easily for sound quality.
Another thing I noticed - the Icon has a hell of a lot of drive, and can power a whole bunch of speakers of varying sensitivities without noticeable strain (within normal listening levels, of course). For example, I'm now running it near full volume with the Mark & Daniel Minis, a virtual torture-test for any smallish amplifier, and it's making the speaker really sing! The Trends & Kingrex crapped out when I tried them last time, with the Kingrex seriously clipping and burning out even at three-quarter volume. The fact that the Icon can drive the near-impossible-to-drive-well Minis says a lot about it, and I'm pretty sure that customers will use the Icon with a whole bunch of audiophile speakers - something to think about in positioning the S-1. The Icon may well be a runaway success on its own.

Post by: HoSaybo on March 26, 2008, 09:06
I think Nuforce provided a cable for this if you look at their pic carefully (the one with the items in the box). I guess some concern will be how to play with other speaker cable as these are not std cables.

Interested in this, but need the question on cables answered as well.
Also, if used as USB DAC, can subwoofer be attached? Website seems to indicate not possible.
Further, since there is a DAC, can we input digital coax/optical?

If you want to use your customise cables you can go down to LHS to terminate one end to RJ45. Make sure it is not more than 24 guage.

Quest you can use the Line Out (for Subwoofer) connection.

No input for digital coax. :( 

Total of 3 inputs:
RCA

Wah piang, it looks like a normal UTP Cat 5 cable with RJ45 on one end and speaker plugs on the other. Looks like normal speakers cables is out of the question.

so, if fabricate at LHS, the speaker cables will still have to be UTP LAN type cable because of the RJ45 jack on the amp....unless can mod....

NuForce Icon Mini Review (Part 1)


First Impressions

Someone should give the art designer an award for the Best Design. Seriously who would have come up with such a beautiful and tastefully design box? From the exterior box packaging to the inside box NuForce really took every detail into consideration making sure it look really good.

Click to enlarge
(http://img141.imageshack.us/img141/4074/frontviewboxbt5.th.jpg) (http://img141.imageshack.us/my.php?image=frontviewboxbt5.jpg) (http://img141.imageshack.us/img141/1526/backviewboxhu9.th.jpg) (http://img141.imageshack.us/my.php?image=backviewboxhu9.jpg)

The packaging box is made of translucent hard plastic and the inside box is white color with a transparent window to show the color of the Icon inside. The inside box sports four slot bay for the amp (Icon), power adapter, stand, USB cables, and RJ45 to banana plug speaker cables. There is also another slim box which contains the power cord and a protective white rubber mat for you to place the Icon horizontally.

(http://img141.imageshack.us/img141/1553/insideviewhg9.th.jpg) (http://img141.imageshack.us/my.php?image=insideviewhg9.jpg)

The unit I got comes in a beautiful shade of red that gives you that expensive, stylish, avande garde look. What I also like is that sexy curve edge body. I simply love the knobs (Volume and Input Selector) on the Icon. It has this nice smooth texture to it and yet gives you that solid tight feel whenever you turn the knob. The volume control is also the on/off switch which gives a click sound whenever you turn it on or off. The headphone jack input can be found at the bottom of the front panel. At the back of the Icon, it sports a clean and simple layout. It come with 3 inputs, RCA, USB and 3.5mm stereo jack, a unique speaker output (RJ45) and a line out (for subwoofer) connection.

Audio

Set up was simple; I hooked up the Icon to my pc through the USB port which now functions as a USB DAC Pre-Amp. Next I connected a pair of Mark & Daniel Maximus Mini (http://www.mark-daniel.com/Pro_En.asp?ProID=47) for a stress test on the Icon. The Mini’s are a very hard pair of speakers to drive with an average efficiency of 82.5db.

Scrolling through my itunes, I selected Eric Clapton’s Tears in Heaven in 320kbps MP3 format. What came next totally hit me by surprise! My initial expectation of this little fellow wasn’t even high however what I heard next completely threw whatever assumptions I had on it. The sound was simply amazing; I could hear Clapton plucking the guitar strings so clearly. It was good clean music with no distortion played out. Clapton’s vocal was so warm and detailed that I could feel his pain and passion when he sang it. The most amazing thing is it could drive my M&D Mini’s! Like I said before the Mini’s are real hard to drive and it sounded good with the Icon.

At a desktop distant of less than a meter it was loud enough for me playing at 10 o’clock volume level. I got more adventurous by cranking it up to almost 1 o’clock. Guess what, it didn’t clip or sound stretched at all, I had to even turn it down as it was getting too loud for my ears. On my previous amp (KingRex) which was driving the Usher S520, it was clipping badly and even shut down when I played it up to 2 o’clock level! Simply put it this way, amps like Trends and KingRex will not come close to it.

Next I shifted the Icon to the hall and hook it up to an OPPO DV-983H and Mark & Daniel Sapphires (http://www.mark-daniel.com/Pro_En.asp?ProID=17). I selected “Smooth Operator” from The Best of Sade album for my next listening test. This would mean a more grueling test on the Icon especially trying to drive the Sapphires which are one of the bigger bookshelf in the Maximus range. I was a little skeptical about switching from Mini to Sapphires but that’s what this stress test is all about, isn’t it?

Holy cow! I couldn't believe what I was hearing, this little chili padi could make the Sapphire sing. Now I am asking myself how on earth could this tiny little amp drive the Sapphires? I am simply lost for words, i couldn't believe what I was hearing. My assumptions had got the better of me again! What came out from the Sapphires was pumping tight bass. The smooth sexy sound of the Saxophone gave me a cool jazzy vibe. Sade's voice was so melodious and warm that i was singing along with her. Details like the beat of the Congo could be heard clearly with every finger knock. I could hear the bass guitar strumming away in the background blending in so well and smoothly with the music. All this was played at a loud volume level at 1 o'clock which the Icon didnt break a sweat. I must really say it sounded even better on the Sapphires.

Inside of Icon

Conclusion

I am still in disbelieve and in total shock of what i was hearing from the Icon. It was able to deliver, perform and exceed above all expectations for its price range. It is clean, neutral, dynamic and not bass shy is what I can describe the Icon. 12 watt is seriously an understatement so don’t be fooled by the numbers. I can assure you that it will be able to drive your speakers and you will be amazed by its sound.
   
Come to think of it, at this price tag the Icon is simply the best value for money amp. 6 key features on the Icon which none of its competitor can do:


It’s a multi-functional amp which performs top notch in every category. 
NuForce has seriously set new heights and benchmark on the Icon. Well done!

Any shop carry this in Singapore? I remember I have to import my super T from Australia and is almost the same price as this nuForce icon. They use the word "Icon" may be sound like for ipod!

I think it is the same class as the sonic T amp. You don't have to look for special speaker. Just look for the one with your prefer sound. Easy matching.for small room. Not suitable for bigger living room.

2. Long enough for your desk top at 1m length.

If you are adventourous bi-amp it, you just need 2 sets.  ;D

To me it sounded neutral. It does sounded warm and not laid back at all.

Most likely you have to buy it seperately. Meantime till the adaptor is out, I'll be making a pair of longer runs.
Anyway I dont see myself spending more than $100 bucks on speaker cables for this set up.

Just an idea. Why not terminate a custom short cable with rj45 on 1 end & speaker binding post on the other end.

In this way, U can freely change your speaker cables.  ;D

But of course the bottle-neck will still be the rj45 cable. If using 8 strands of AWG24 as in a standard Cat5 or 6 cable, 4 strands as + & 4 strands as -, the largest gauge size possible is 4 x AWG24 which is about AWG18.

So it might not be worthwhile to buy speaker cables that r much larger than AWG18.

The line out is a 3.5mm stereo jack so you will need a y splitter 3.5mm jack to RCA. Actually where do you want to output to?
The Icon can also function as a pre-amp which outputs to a poweramp or monoblocks.

From NuForce Casey

Larger diameter is not necessary better sounding.   I would suggest you can make a Cat3 cable and compare to Cat5 sound.....I am sure this will become interesting.....

The best high-end cable I used are extremely thin gauge.  Our internal speaker lead in Nuforce amps are 100 x 32ga Litz wire.  As you can see, I am sort of leaning towards small gauge.

BTW, there are 3x 24ga in each leg of the Icon speaker cable.  3 twisted pairs were dedicated for speaker signal, 1 pairs were used for ID'ing S1.   If I am not wrong, 3 x 24 ga = 19ga, which is very decent for a 12W output.

This is more of a desktop amp than a DAC otherwise it will have gold-plated RCA out instead of just input. Hopefully newer revision will have proper speaker binding post as well. Chamoxa is bringing in the Styleaudio USB DAC and I thnk that suits your needs better.

Post by: Quest on March 28, 2008, 15:46
It's not about the features. It's about fitting the user's requirements.

I agree with Knight_Rider that if you are looking to use this purely as a DAC, the connectors aren't exactly suitable. Would the Icon's stereo minijack output beat a lower or similarly priced USB-DAC with proper RCA outputs? Nobody knows, but it means an investment in ICs and a higher cost for all the features you're not using - even if we admit that the Icon is good value.

I'll probably give it a test against my external/internal soundcards and SB3 when I get the Icon.

I dun foresee him using the rest of the function or to switch between functions. (esp 1 and 2) I did not said it sound bad or can't be use but I would still prefer proper output for the job IMO. Like I said I would like to see better implementation in the next revision. I am just giving him another option no need to be so agitated. Peace.

No lah not agitated just misinterpreted  ;D

I totally agree with the same amount of money he will just need a dedicated USB DAC with the RCA connector he needs. However where Iam coming from is savings, VFM and performance. One important thing on the Icon that i didn't mention that it will be a Preamp USB DAC function. Also for those that have been using their ipod or external device connected to their amp they can also re-use the same cable for line out. Of course a RCA output will be much preferred  :)

take the guesswork out of it. Actually its really your perception upon listening that matters - if you think the SB DAC works better then use the analog inputs, otherwise you probably need to bypass the SB altogether (unless the SB outputs USB)

Title: NuForce Icon
Post by: Darthfunk on March 29, 2008, 23:58
Some desktop users ask me a couple of questions about hooking up to Active and Passive speakers which i think are very useful information for those who are interested in the Icon.

For Active speakers set up, the Icon work as a USB DAC.

Use the LINE OUT to connect to your active speakers be it 2.1 or 2.0.

For 2.1 - LINE OUT from the Icon to the 2.1 sub, (the sub is the pre-amp) the sub is the one powering the speakers.

For 2.0 - LINE OUT from the Icon to the 2.0 speakers. One of the speaker has a LINE IN.


For Passive speakers e.g Mark & Daniel Maximus Mini (http://www.mark-daniel.com/Pro_En.asp?ProID=47)

The Icon act as a USB DAC Preamp. Therefore you will use the speaker output on the Icon (RJ45 to banana) to connect to the speakers.


Therefore the Icon is a multi-functional amp which act as a:
1) Integrated Amp
2) Pre-Amp
3) USB DAC
4) USB DAC Pre-Amp
5) Headphone Amp
6) Power Amp

I'm a big fan of both NAD and class-D amps; and both will sound good. ultimately its what speakers your friend has and whether they match pleasantly for your friend. He has to listen to both and decide which is preferable to his ears.

I was driving my usher s520 with trends TA10.1 and now driving it with Nuforce Icon now..... source from PC(usb) and oppo 980(rca).....i must say its really impressive....after 2nd day of listening.....im really really impressed with it....its not the best out there....but for its price n size.... nothing of its range comes near to this.

Title: A relative review and some tweaks...
Post by: hotbird on March 31, 2008, 00:50
Let me start by saying that I already own a Flying Mole CA S-3 for about 2 years, long before miniature amps like Trend-Audio/Kingrex appeared on the market.
(http://www.audioaffair.co.uk/images/uploads/FLYCAS3d.JPG)
At that time  it cost me much more than a grand, but it was rated at 30W and was the most powerful integrated amp of that size then. It drove a pair of Proac Tablette Reference 8 Signature Reference (sensitivity 86db) in my bedroom with much headroom to spare,
(http://www.positive-feedback.com/Issue18/images/tablette.jpg)
The Flying mole was connected to a Squeezebox through Acrolink 2050 interconnects. The Squeezebox streamed music wirelessly from my PC or directly from internet radio stations.
I also already owned a complete Nuforce P9 reference pre-amp and S9V2 monoblocks so I readily chanced upon the opportunity to try out the Nuforce Icon when it was released, knowing that it's going to be another killer quality class-D amplifier on par with the bigger brethen that I am already enjoying.

So how did it compared to the Flying Mole CA-S3 amplifier that was about 3 times more expensive?
Read on to find out.... ;D

Firstly, my test discs
1)  Shelby Lynne : Just A Little Lovin'
(http://www.musicbox-online.com/images/just-a-little-lovin.jpg)
Laid back sultry female vocals with minimal acoustic accompaniment, the pefect CD to test transparency and resolutin and imaging.
2)  Mike Oldfield 's latest Music of the Spheres
(http://ecx.images-amazon.com/images/I/51iIbQ9K2EL._AA240_.jpg)
Track 13 and 14 to test the brass of the trumpets and the dynamics of the system
3) Naotaro Moriyama 2007 Concert at Himeji Castle in Japan
(http://ec2.images-amazon.com/images/I/61DT2d18wFL._AA240_.jpg)
Tracks 5,6,7,8 for live concert presence and soundstage/imaging and a nice DVD to view (via Oppo 970)

Firstly I listened to my trusty old Flying Mole CA S-3 amp connected to the squeezebox as a reference first. Very clear and nice....got used to more or less how it sounded like. I then switched to the Nuforce Icon and heard the same piece of music again. What!!! How can it be....I am hearing more resolution and better soundstaging with the Nuforce Icon (note that I had to turn the volume knob on the Icon to 3pm vs 12pm on the more powerful CA-S3 amp to match volume), Furthermore it also sounded very neutral with good bass control, it's character just like the its senior brethen, the Nuforce S9V2. The Flying Mole was a bit harsh and bright by comparison. Alas, a 1000 plus made in Japan Flying Mole CA-S3 amp has been toppled by the little Icon that is only 1/3 the price.  To further confirm these findings, I hook up directly an Oppo 970 universal player to play the above test CDs. I was floored by how much better the little Icon sounded. Should I cry over the spilt milk of owning a Flying Mole CA-S3 amp or laugh in celebration of finding a better class D amp that not only could drive the Proac Tablette with finesse but also hook up directly to a PC via USB DAC connection (stupid CA-S3 only have 1 RCA input via comparison).....

Next I tried the USB connection by plugging it into my notebook, Whee!!! no installation CD required to install the drivers, my notebook automatically detected the Nuforce Icon and installed the drivers by itself.
Once installed, I was ready to play a list of recorded MP3 via the Itunes player. Wait....how come no music. Oops silly me, I forgot to turn the selector knob to to inut 3, the USB DAC . That corrected, I was soon playing my favourite mp3, wav files directly to the Nuforce Icon. A piece of cake  ;)

Always itching to tweak the best out of any audio equipment, I looked at ways to further improve the perfomance of the Nuforce Icon.  I found that the power supply to the Nuforce Icon was a little 15V AC-to-DC rectifier box that looked very much like my notebook computer power supply. That could be very much improved, since i had a much better DIY external power supply that can supply 12-15V. Knowing that my Squeezebox performance had already improved much further by swapping its supplied wall-wart with this DIY supply, I quickly exchanged the Nuforce power supply unit with this better DIY one. Bingo!!! What I heard was now even better tranparency, refinement, more body and bigger soundstage. Thus, I hope Nuforce brings out a better PSU option upgrade in future as it's a no-brainer  ;D ;D ;D

I also felt that the Nuforce Icon sounded a bit quieter with more definition lying on its side with some damping plate on top than resting vertically on the stand... :)  (always keep the CG low for the most stable configuration ;-)

The ICON! small, simple and powerful.

First demo, the integrated mode driving M&D 83db 100W Sapphire. This mini 12Watter is able to push through without lossing clarity and bass. If anything can do M&D speakers, it can do with anythg high DB speaker.

Next, Bi-amp mode, one ICON for one speaker. Less demanding on the volume, better control on bass, mid is also more present. We push its limit of 3 o'clock, the charm still hold and maintain as expected. 

Overall, worth to invest in two ICON, one for each speaker, im sure it give your speaker a push like a power amp. USB connector give PC gaming or listen at high standard, a Pre amp with the 35Jack out. Multi function. Design fit into modern style, sure pass on WAF.

Thanks to Darthfunk for his kind hospitality!!! The icons were quite impressive. The sound stage and resolution was very clear on the jazz pieces and the Eva Cassidy cds which was played through this M&D. But somehow it did not do as well on an orchestral piece which I brought along. It offers a clean headphone output and Heat is definitely not an issue with this amp for those who are concern  :)

Keglar's Impressions of the NuForce Icon on VR-Zone (http://forums.vr-zone.com/showpost.php?p=5101296&postcount=11)

I wouldnt even call this a review but its more like just my personal experience with Nuforce Icon. For whats writen below is what i personally feel, don't shoot me if you dont agree with me. I just wanna share how i feel about icon as most of us have not even heard it.

A little background on me, im using Usher s520 with canare cables and driven by trends TA10 in my bedroom.

The moment i got the oppo dv-980 and Nuforce Icon i was really surprise by how well they design the packaging. Seldom i see audio stuff with really detailed design for packaging.

I replace the trends with my icon for 2 reason, i need to connect to PC(USB) and Oppo 980(RCA) at the same time. So i could just switch between them, i've been looking high and low for such device. Integrated amps fits into the picture nicely but most are huge in size or over my budget like nuforce IA-7 which i like it very much.

Thanks to Darthfunk bro, for bringing us Icon. As it really solve my headache, i use to plug in plug out the rca from my old dvd player n pc. I realise soon or later either cables or connectors are gonna give way.

Switching from Trends to icon, immediately i feel the difference in terms of the nature/characteristic of the sound. As i was listening i was exchanging sms with darthfunk and i mention about the wider soundstage and lack of mid bass(lol). After a few hours of listening,(sorry im trying to let it run in so i on it even im not at home) on the 2nd day, i notice the characteristic changed abit. More warm but unlike tube amp and wider soundstage compared to trends, alot wider.

I tried watching dvd movies and concert with it, i feel very significant improvement over trends.

Ok i will stop here, else people might think that im trying to say this amp is better than any more than $1,000 amps out there. Im not! but for $369 its definitely worth it as it comes with the DAC built in and switching between USB, RCA and line out with ease. Im sure many of you out there had or having the same problem i faced. For bedroom most of us would try to aviod huge integrated amps.

Btw i got the red icon to match my usher s520 which is red as well.
Although the color not exactly the same but it complements it well.

Will update again when i get better rca and speaker cables....hee

Wow, now i'm impressed that it can drive the ProAc Tablette Ref 8 Signature, Usher S520 & M&D Sapphire !!

I noted most mentioned the volume has to be pushed high like 3 o'clock, can the amp's 12W cope? Will doing that introduce any audible level of compression to some music?

Quite tempted to try a unit as poweramp for a study room... haha... :P

Are you gonna use it solely as a PC amp to play your collection of mp3 or whatever or are you gonna use it for some serious listening like biamp your speakers, using as a preamp etc?

I mean after all your testing/experimenting with the amp, where will you use it eventually?

I'm looking to integrate my desktop into my main system, hence i think i will need a DAC and also a preamp ( to receive signal from both the DAC and CDP).

If the Icon can do both competent then all's well and good. But like siriusly cold said, maybe i should consider a proper pre-amp and another dedicated DAC  ???

No, you make perfect sense!
I was considering the future option of adding smaller sized speakers that I can place on my desktop for late night listening where listening at loud levels is impossible.

But after weighing all the options I think I will take ur earlier advice and focus on getting a dedicated pre-amp instead, and look for a another DAC, thanks!

Input 2 is for RCA in which is your CDP. For USB DAC or USB DAC Pre-amp usage you will be using input 3.

Nice review from 700mhzNMR
http://forums.vr-zone.com/showpost.php?p=5120803&postcount=48

Just received my nuforce icon today in the middle of a lecture, the guy who delivered the amp was very nice to drop it off in sch for me (as i reside on campus), very thankful for that. he's very well dressed too.. in long sleeved, kinda didnt expect that.

(http://i303.photobucket.com/albums/nn145/700mhznmr/d94361ed.jpg)

(http://i303.photobucket.com/albums/nn145/700mhznmr/79b348f2.jpg)

Decided to get it because of nuforce's reputation, and that it also had an integrated DAC, so i can use it with my computer to play the mp3s that i painfully encoded from cds via EAC

First up was to test the DAC, and line out to a pair of computer speakers. Very good! Everyone would have remembered how shouty, and how glaring klipsch speakers sound.. the sound pressure's exotic, but not for long term listening. However when i connected the nuforce's line out to the speakers.. suddenly the soundstage became wider, and more laid back. the bass was no longer boomy, instead, is very clean. it seems that everything had mellowed, and became warmer.

(http://i303.photobucket.com/albums/nn145/700mhznmr/805b9f43.jpg)
Tested a few tracks on the klipsch
jacque's loussier's pastorale - percussion was very full sounding, no longer hollow, clarity's much better, the shimmers of the hi-hats were good.
caiqin - (track 2/3 of the ming-ge album) - synergy and dynamics were pretty good, however voice seemed a little recessed.
ray brown - fly me to the moon, wet juicy twangy doublebass, very cleanly rendered, without bloatiness nor boxyness

(http://i303.photobucket.com/albums/nn145/700mhznmr/ddb9d854.jpg)
Next was an evaluation of the headphone out put with a pair of shures. without the attenuator of course. the biggest weakness of this amp was very obvious on the earphones, at volume 0, i could hear the slight AC hum/buzz in the background, very faintly.. i think the PSU needs to be worked on, but when you turn up the volume, music drowns everything.. (but still noise floor is important no?), maybe after i get home in may i'll try my diy mil-spec power supply on it.

Ignoring this weakness in noise floor (this is only audible if your earphones are very sensitive), on the music..
ran a few evaluative tracks through, monty alexander's once i loved, joan baez's diamonds and rust, norah jones - new york city..
very good! by far one of the most decent headphone outputs i've listened to. comparing to the $750 IQube headphone amp, the synergy and clarity is just as good, and soundstage's pretty impressive, no longer compressed. sheffield lab's percussion was good, it was as though my earphones suddenly was more able to push more air.. (although its armatured)


(http://i303.photobucket.com/albums/nn145/700mhznmr/b4906564.jpg)
the final test.. my dad dropped by on campus and brought in a pair of speakers from my bedroom.. thanks dad!!..

it was almost pushing the output to the maximum, the amp didnt like the poor sensitivity of the spendors at 83-84 db/watt, volume knob's almost past 3'o clock. on this pair of usually very neutral sounding, non-fatigueing pair of speakers, performance is definitely excellent in my opinion. worried about the sound stage, i threw in elgar's cello concerto in e minor in first.. nice and soulful, timbre was pretty refined, spatial separation of  instruments was good.

james blunt's 1973 went very nicely, vocals were forth coming and enjoyable

Flamenco fever, (direct from live to LP), track 1 was well rendered, but the flamenco guitar sounded a little hollow, would prefer a tighter/scratchier sound

kobukuro's all singles best track 2 (some japanese title), nice!! smooth. interestingly warm for a D-amp.

finally decided to run erich kunzel's 1812 in.. hoping that the amp wouldnt clip at max volume.. well it didnt, but the setup in this case lacked the orchestral attack (cant expect too much from a pair of bookshelves + 15 watts no?).. a little compressed.. but still, good in my opinion.

so is this nuforce icon thing worth the $$? my opinion is.. yes. what more can i ask of something of this price range? its too good to be true!! just a few areas that can be improved on, and definitely a good/correct speaker to match it will bring out the potentials better. With the nuforce, takes computer audio to greater heights definitely.

So much raving.. what are the gripes?
1) Power supply & noisefloor needs improvement
2) Sounds warm, but not as organic.. but hey. its a D-amp.. pretty good already
3) Doesnt seem to drive insensitive speakers that well, my 2a3s  (3watt) at max volume could drive my bookshelves harder (no idea why)
4) Amp has to be turned on before USB cable is plugged into computer. If not turned on, the device wont be recognized. but if plugged when turned on, there's a slight "pop" sound.. which is quite unnerving.
5) interesting cables.. but they seem pretty ok so far.

thats all for now.. busy weeks ahead with the exams.. well at least there's some salvation in music for me whenever i'm tired/sick of work.

btw just a disclaimer - i dont have golden ears. i'm not a super expert in audio stuff, i believe in enjoying music more than equips

NuForce Icon Mini Review (Part 2)


So impressed by it's sound, performance and multi-functionality, I decided to get a 2nd unit for my bedroom. I was so Wowed by the overall Icon experience that I didn't think twice when i was offered the last Red unit from the distributor. Who wouldn't for such a low price tag, in fact i see no reason for not getting 2 units to bi-amp which will definitely give you that immediate sonic improvement you are looking for. 

(http://i295.photobucket.com/albums/mm150/funkigene/HorizontalView1-1.jpg)

Bi-Amping?

Yup that's precisely what I am talking about (bi-amping), the Icon is so versatile that it can function in many modes. Being a proud owner of a pair of NuForce Reference 9 V2 SE, I was intrigue in how two Icon's will sound in Bi-amp mode. This is not meant to be a comparison to its award winning brother, to do so will be crazy and a total lack of respect.

(http://i295.photobucket.com/albums/mm150/funkigene/Bi-Amp-1-1.jpg)

Owning two sets of Icon means being more adventurous and bi-amping has been something that i wanted to try on the Icon. Hey if it can drive amp killing speakers like the Mark & Daniel's, I am sure with two units it has something up its sleeve to surprise you. 

The Mark & Daniel Sapphires are not shy when it comes to more power and will always perform best when feed plenty of it. Set up was simple, each speaker was powered by an Icon connected through a y-splitter RCA Interconnect to a OPPO DV-983H.

In my earlier (Part 1) (http://www.xtremeplace.com/yabbse/index.php?topic=50938.msg385337#msg385337) Mini review, I played Sade's “Smooth Operator” which was surprising good at 2 o'clock volume level. This time I’ll be running it with two Icons.

(http://ecx.images-amazon.com/images/I/21uSakEALaL._SL500_AA160_.jpg)

Wow sure enough I could hear an immediate difference! The Sapphires was definitely more controlled with doubled the power of two Icons. Sade was cruising so smoothly, vocals were involving and with a much wider sound stage. The Sapphires were now performing with a greater punch and drive. Bass was alot more deeper and fuller. I also crank it up to 3 o'clock and it was able to drive the Sapphires with ease and comfort. Playing at this level and with an amp killer like the M&D Sapphire will surely make any puny amp clip, distort or shut down. Now imagine running two of this on a higher efficient speakers of 89db, it will definitely sing effortlessly.

Next up on my play list was Wynton Marsalis Quartet (The Magic Hour) track 1 – Feeling of Jazz. This is one of my favorite Jazz CD and my all time favorite jazz trumpet player Wynton Marsalis.

(http://ecx.images-amazon.com/images/I/41STXX61N9L._SL500_AA240_.jpg)

It was such an immediate impact with the bass strings strumming away in the opening. With Dianne Reeves deep strong vocals powering away, it just felt like she was smack right in front of you. Stereo imaging was excellent making each instrument easy to follow and integrating every elements seamlessly. With two Icon you can really feel the robustness it has brought to the Sapphires. What the Icon present was a solid and spacious sounstage. Imaging is precise and believable. It really got me into the mood and I was toe tapping to the whole Jazzy vibe.

Headphones

My intended 2nd unit is for my bedroom and I intend to match it with the S-1 speakers. However I wont be seeing the S-1 till May so what am I going to do with it? Well a very simple solution, I decided to use them with my headphones.

Having left the music industry for many years, I have never forgotten my roots of how I started my music journey. From my bedroom DJ days to a season club jock, I always believe in investing a good pair of monitor headphones. You can cut back on vinyls but definitely not on headphones. Every single beat and snares are essential when mixing two tracks together in a loud noisy environment. I have owned headphones like Technic’s RP-DJ1200, Technic’s RP-DJ1210 to Sennheiser’s HD-25,  just to name a few. My favorite pair is still the Sennheiser’s HD-25, this are a sturdy, firm and comfortable pair of  headphone that can also withstand physical abuse. It delivers deep tight bass, refine mids and clear high notes which is perfect for my genre of music.

(http://ecx.images-amazon.com/images/I/51MPVZSsl-L._SL500_AA240_.jpg)

I hooked up my good old iPod classic into Icon’s input one line in. All song formats were in Apple lossless audio codec (ALAC). Selected Alecia Keys “No One”, for its Hard pumping nasty basslines. My first impressions was it sounded clean, dynamic and punchy. It also offered bags of pace and details. The sinuous bassline is delivered with solid impact and clean sound. Alecia Keys never sounded so good before on my headphones.

(http://ecx.images-amazon.com/images/I/51N7iaF37RL._SL500_AA240_.jpg)

Up next, my all time classic funkadelic track “Virtual Insanity” by the one and only funk soul Meister Jamiroquai. It delivered the song with speed, pace and punch although a little lacking in the mids. It really got me into the funky mood as I was nodding my head to every grove of the beat. Overall I am pretty impressed by what it can deliver on my headphones.

Final Words

What can I say this little wonder has shown its true class and pedigree. Its price tag is really an understatement for its amazing performance and versatility.

What I would love to see is a add on PSU to give the Icon that added juice for that added punch and drive. With that said, NuForce has mention that a 40 watt power supply is in the making and would be release in a month or two. Another exciting news is NuForce will also be releasing an affortable ($79 USD) earphones that “will sound better than anything on the market, even those headphones costing 2 to 3 x the price.” A very bold statement from NuForce which they have so far live up and deliver above all expectations. It seems like a whole bunch of accessories would be releasing soon to complement the Icon. For now its back to more listening pleasure with my little precious gem!

NuForce Icon-1 arrived
Posted 04-08-2008 at 02:51 PM by Sasaki
Updated 04-08-2008 at 10:56 PM by Sasaki

I bought a new desktop small amplifier NuForce Icon-1.

(http://vaiopocket.up.seesaa.net/image/icon1c-thumbnail2.jpg)

NuForce is a high-end digital amp manufacture and they are known for its high performance proprietary Class D amp technology. it produce amazing damping factor of 4000. This means the amp has great driveability and control ability for speakers.

Here is their web page, follow the menu products -> Icon.
http://www.nuforce.com/

Icon-1 is their first consumer entry with a good price tag that is $250($199 for intro).

In addition to the high performance at a good price, Icon-1 has many features. USB DAC, Pre out and headphone amp.
Especially for HeadFier, Icon-1 has a decent discrete headphone amp. NuForce is also preparing their IEM for $79 estimated.
They also mentioned the Icon Mobile which is battery powered amp in the next year .. this could be similar to iQube??

One of unique aspects of the Icon-1 is the implementation of speaker cables. Icon employs CAT5 (100base-T) network cable for the speaker connection.

(http://vaiopocket.up.seesaa.net/image/icon1f-thumbnail2.jpg) (http://vaiopocket.up.seesaa.net/image/icon1g-thumbnail2.jpg)

NuForce will launch companion desktop speaker S-1. S-1 has a similar RJ45 port and when connected via the CAT5 cable with Icon-1, an equalization network will be activated. Normally the cross over network is implemented in the speaker but for this combo seems like the Icon-1(amp side) has a built-in cross-over like circuit and S-1 has not. I am not so sure about this approach but quite interesting.

For sonic impression, I wrote a user review on the amazon.com (http://www.amazon.com/gp/product/B0016EPS7E/sr=8-1/qid=1207358234/ref=olp_product_details?ie=UTF8&me=&qid=1207358234&sr=8-1&seller=). Please refer to that.

This amazon.com is actually a pre-sale. I heard the regular sale will begin from the 25th of April.

NuForce is a high-end digital amp manufacture and they are known for the high performance proprietary Class D amp technology.
I knew their product on several auditions, I had a high expectation on this so I jumped at this chance to get it. It is well rewarded.

First, I connected Icon with my PC via USB DAC and YAMAHA desktop speakers. The sound quality of Icon was very nice from just out of the box.
I thought the ability is beyond the desktop speakers. Finally I set it up with my best speaker Dynaudio twenty five special via LINN IKEMI.

I was amazed by the quality of bass reproduction. It's so rich and deep, I can not believe it from the tiny size of Icon-1. Lower register of the speaker is well controlled as expected from Nuforce reputation.
Second, I like musicality of the Icon. Icon is not sterile nor dry without loosing any virtue of the Class D amp. In fact, Icon sports a high resolution and low distortion.
I think the overall performance is far beyond the price.

As a bonus, Icon has a decent headphone amp. This is not a cheap trick, Icon employs a discrete circuit for the headphone amp. Again, the sound quality is very good, this is no mean feat for the headphone out of audio amps.

I highly recommend this to every audio fans from the beginner who use PC mainly as a source to the audiophile who want a second system.

One way to decide is to connect a cd player to the nuforce RCA input and set the volume on nuforce to desire level. That should be your listening reference point. Mark or remember it. Now, with the USB DAC, adjust your PC volume to desire level. From now on, use the nuforce volume control as it is more easy then the PC control. You should have use passive speaker rather than active speaker to take advantage of the D-amp effect.

Hey Guys

I Know the icon can also be a power amp, dose that mean i can use it with out it being connected to my computer although that is what its implied for and pre amp usage. I also know its better with monitors, but can i use it as a stand alone amp for say http://axiomaudio.com/m2.html. Im kinda having trouble seeing if it will be enough power or should i go with a Sonic Impact 5065 Gen 2 T-Amp with Power Supply? Sorry if yall are getting fed up, i have been researching but im confused on this.

The sonic do not have built-in DAC so nuforce become the better choice as there are on the same power output class.

Post by: nuforce-jason on April 17, 2008, 10:49
The 12Wx2 power is RMS power. A lot of the amp's peak power requirement is delivered by the power supply. So don't under estimate the power rating. See the 6moons.com mini review of Icon.  To further boost the performance, you can purchase the 45W PSU from Nuforce at $45 or find any good power supply on the market that supply 12V DC.

The question of bi-amping has come up frequently, especially with USB input (which you can not use the Y-cable to split the signal). See

Post by: SLT on April 18, 2008, 13:20
What's  the frequency response of the S1 speaker?

? hz -? khz

Is Biamping necessary due to the lack of power?

Specifications for S-1 speaker:

3.5" Titanium full-range driver
Neodymium magnet
Impedance: 8 Ohm
Sensitivity 87dB 1W/1m
Frequency Response: 80 Hz to 20 kHz
Maximum power input: 30W
Dimension: 9.5" x 6" x 4.75"
Weight: 5.5 lb each

Description of S-1 (from Nuforce website):

The S-1 is a desktop speaker designed to coordinate with the Nuforce Icon. Specifically, a standard RJ-45 Cat 5 cable signals the Icon's equalizer to optimize the S-1's response characteristics. The tight integration with Icon and unique design enable S-1 to achieve sonic performance equivalent to speakers costing several times its price.

The S-1's full-range, Nuforce-engineered driver utilizes a lightweight yet rigid titanium cone, a die-cast basket with a vented voice coil, and a neodymium motor structure, all of which contribute to the speaker's excellent linearity and power-handling capabilities.

A waveguide feature similar to that of NuForce's top-of-the-line S-9 loudspeaker accounts for the S-1's exemplary midrange gain, dispersion pattern and eradication of diffraction artifacts.

There are three basic benefits to the waveguide:

It controls dispersion thereby reducing the effect of nearby reflective surfaces.

It reduces speaker cone excursion and therefore distortion, while increasing dynamic headroom.

It reduces power demand from the amplifier and therefore lowers distortion while increasing dynamic headroom.

The S-1's well-damped enclosure consists of audio-grade MDF (medium-density fiberboard).

Sorry guys, newb alert!!

I currently have a Macbook Pro > Apogee Duet > powered speakers.  It looks like I'm gonna stumble into a pair of Monitor Audio RS1's, and I think I'm gonna switch to those for my computer-as-source speakers (moving my AudioEngine A5's to my office at work).  Anyways, a few questions:

1.  Based on the several reviews I've read, the Icon should be able to drive the MA RS1's (rated @ 90dB sensitivity).  Is there any reason for me to think otherwise?
2.  The RS1's come w/ double binding posts for bi-wiring.  How am I gonna be able to bi-wire given the RJ45 speaker outs on the Icon?  Heck, do I even "need" to bi-wire the RS1's?
3.  The primary question:  how exactly do I hook this up to my Duet?  Can I use this w/ the Duet?  I have the stock break-out cable....

Thanks guys!!

Macbook Pro > Apogee Duet > Icon (analogue input) > speakers
or
Macbook Pro > Icon (USB input) > speakers

since you have the Apogee I'd recommend you to try both and compare the result - not for any reason other than to decide which one to use

nobody needs to biwire speakers. however you may want to bi-amp - in which case you will need two Icons :)

Thank you so much for the response!!  But I'm still a bit uncertain about how to use the Icon w/ the Duet...  The Duet breakout cable only has 2 sets of XLR outs & 1 set (L & R) of speaker outs (1/4").  Currently, I use a y-cable (1/8" mini connected to the left A5 speaker on one end; on the other end, 2 (L & R) 1/4" mono TS connected to the Duet cable speaker outs).  Would I use the same 1/4" outs from the Duet cable & get a special cable to connect to the Icon analogue input you speak of?  Is it just RCA inputs on the Icon (I've looked at pictures, I think they're RCA)...

Any bros here who got it early face these problems?

Anyway, you can change the board free of charge according to the post above :)

In the 1st limited production Icon (shipped before April 23), the USB has several minor problems:
1) If it is powered off and then on, you have to reconnect the USB cable to the PC for the PC to recognize it.
2) It might not work when connecting to a USB hub
3) Speaker L/R is reverse (only when input is USB). This can be fixed by configuring the audio software or swaping the speaker cables.

But don't worry, if you purcahsed it from Nuforce, you don't have to do anything. We'll send you a replacement board with instruction (and you can keep the existing Icon board) next week. If you purchase it from a dealer, contact the dealer. He should be getting the parts later next week.

From NuForce Jason

I will try to answer several questions here:

1) Don't worry about the Cat 5/Cat6 RJ45 to Banana speaker cables. It is not an issue. At low power, ethernet cable has high bandwidth, good shielding. And the extra wire allows Icon to recognize S-1 and activate the internal equalizer (this is active crossover since S-1 has not crossover)

2) We expect most people to use Icon with S-1. If you have an existing desktop speaker, fine, you can use Icon to drive it. If not, please wait for S-1. It will sound better than any desktop speaker on the market.

3) The Icon is packaged for general consumer (that's why we included everything), not for your typical audiophiles.  We will be providing several accessories for audiophiles:
a) 45W power supply (instead of the standard 25W) at $45
b) 2meter black RJ45 to Banana (plus a RJ45 coupler to extend it to any length)  $39
c) RJ45 to speaker binding post connector box (the case is the Icon case so you can get matching color)

We will also sell you an Icon front panel (to open up Icon to mod it, the front panel and volume knob can get scratched or damaged) for $10 (estimate price) so you hackers can go mess with it (no warranty).

From Jason again on their cables:


I got more info for the Icon cable:

Gold platings are all 15-micron (standard is 2-5 micron) on all Nuforce cable connector
The standard speaker cable is Cat5 ( 24 Ga x 8 )with high quality copper and gold plated terminals.
We will be selling a 2meter Cat6 speaker cable ( 22 Ga x 8 ) plus Rj45 coupler (for extending the cable further).  The set list for $39.95
3 of the Cat5 wires are used for each channel (3 left, 3 right, 1 for detecting the presence of S-1).

Therefore our cables are not standard off the shelf cheap wires. They are premium quality wire custom made for Nuforce.

I need to clarify that we want to be open with Icon's support but at the same time we need to have a policy that protect our customers and the sound quality of Icon.
Therefore by publishing the spec of the power supply or RJ45 pins, we enable a few customers to try out other solutions. But keep in mind that any use of non Nuforce power supply (including battery) or hacking into the circuit board WILL VOID THE WARRANTY.

DF, thanks for that picture. Is the cable in use the standard cat 5 Cable?

If yes, then the following way of implementing it would have yielded better (audio) results. The orange pair typically has more turns/metre than the other pairs due to a computer data spec.
Twisting + and - of the  remaining pairs would've canceled out noise.

1 Empty (reserved for S1 EQ switch)
2 Empty (reserved for S1 EQ switch)

Just got mine. Tested with PC and SB3.
Only issue is speaker cables are really too short for my PC setup..

No problems with loudness at all. I clock the dial at half or less than half and it reaches my regular loudness (then again I listen on my AVR at -60 usually).

Sound quality is as clear as expected. Haven't really made up my mind about it yet, but it sounds more delicate than my XR55. Shall let it run in more first. :)

Totally silent? As in zero noisefloor? Cos I saw a comment in headfi about this as well.
Well, I can change powercords and so on to test first. Basically when I just on the set, I can hear some background noise already, regardless of volume set. It's quite minor though, probably about 10-15db.

Its been quiet so far. Hmm let me go test it again unless my ears are not sensitive enough :P. You are not talking about picking up recording noise right? Cause it does pick up recording silence in the background on certain good recordings.

Hmm never thought of changing to better powercords, still using stock wall wart. Let me know if it does improve the sound.

Yes, not recording noise. I mean even when no source on, there is this background noise.
Maybe since my speakers are more sensitive, they may pick up more of such things? I put my volume to about 35-40% now.

Powercord i realised i lent my spares to pete and francis. Gotta collect 1 back to try. :P

Title: Re: NuForce Icon owners / discussion thread
Post by: Darthfunk on May 01, 2008, 14:26
Startup Condition

The principle of Nuforce amplifier is based on self-oscillation with the speaker as part of the loop. The self-oscillation requires input signal around 20mV (+/- 2mV) to start. Due to the analog based design, speaker's impedance and natural variations in components' values, the self-oscillation might start with different input signal strength and delay. After the oscillator has started (within the initial 3 seconds), it will continue to oscillate even when input signal is not present. This design characteristic resulted in different startup input signal strength or delay time observed from amplifier to amplifier (it could be different between two channels within an integrated amplifier).

Static Noise

Unlike traditional Class-D amplifier that utilizes a constant PWM to modulate the audio signal, Nuforce amplifier employs a self-oscillating circuit that switches the MOSFET at 500 kHz, and utilizes an ultra-fast feedback operating at 1 Mhz to correct for the THD almost instantaneously.

(http://www.nuforce.com/picts/Feedback-Error-Correction.jpg)

The above system illustrates a simple amplifier with feedback. The feedback network takes the error at the output and inject to the summing junction at the input, in order to ‘cancel’ out the harmonic distortion.

However, when there is no music, Nuforce amplifier may have a higher background noise. It is adding noise to the system in an attempt to cancel out distortion, but since noise being the only signal present, it could not be ‘cancelled’ out. The result is higher noise floor when listening (putting the ear next to) close to the speakers.

my first impressions connecting this to my entry level monitor audio bronze 2 speakers and a SB3 - the highs and mids are lacking (could be speakers, need longer speaker cables to test on my floorstanders), everything is as if there is a "veil" put over the sound but i gotta admit for something of this size - the bass is amazing :p I need to listen to it more to give a fairer review but now not that impressed...yet  ;D
Title: Re: NuForce Icon owners / discussion thread
Post by: Quest on May 04, 2008, 08:32
lol.. i'm also having problems testing the Icon due to speaker cable length. Similarly, first impression wasn't that good. I have not had to have a very critical listening session, but my initial impressions are:
- Highs seem more recessed than I am used to. Not sure if this is because this is a more natural level, or because of the difference in acccessories (silver power cord, silver cables, bi-amp) compared to normal set up.
- Need more listening to comment about soundstage as I can't test properly for it (LR speakers not in perfect position).  So far, I find that the separation is good, but soundstage is less forward than I am used to.
- Conversely, actually I'm quite impressed by the mids. It's detailed and full. More natural than my XR55 in this aspect. Bass production is good.
- Analog from SB3 seems slightly better than on USB on PC. Also have yet to do proper A/B testing.
- The background noise is more or less always there, but hardly noticable. I just happen to always hear it during quiet passages..

Overall, having listened to quite a number of integrated amps within this price range, would say this is worth an audition if you like this type of sound and are looking for something under the sub S$1k range. Of course, bear in mind you don't have a remote and have weird speaker cables to deal with.
Title: Re: NuForce Icon owners / discussion thread
Post by: Darthfunk on May 05, 2008, 10:03
Hey Quest did some further testing last night. You are right that analog sounds much better. Quest let me know what you think of the cables i pass to you.

Anyway since i have been using the Icon for quite some time already some observations i have notice.

1. Analog sounds much better.
2. Design for near field listening.
3. Its build with multi funtionality but its core strengths is in its amplification, USB DAC sounds pretty decent but not its key strength.
4. More juice is needed to give you that extra punch. The 45W PSU is definetly a warm welcome.
5. Realise my DIY cables dosent sound as good as stock? Awaiting for the 2m premium cables defintely looks nicer and better build quality.

Hopefully can get hold of the S-1 soon. Interesting to find out how S-1 will trigger the Icon's build in equaliser.

Here is the recommended/optimal volume setting when Icon is use as a USB DAC or Pre-amp.

Here is the reply from NuForce-Casey in audiocircle (http://www.audiocircle.com/circles/index.php?topic=52636.msg487149#msg487149)

1) PC master volume level setting

Put the Windows software volume setting at MAXIMUM

2) Icon volume level setting

It really depends on the speakers' efficiency.  I would try to stay between 12 to 3 o'clock position.

3) Volume level setting for active speakers

If using Icon as a preamp, then you want to turn active speakers to the maximum volume setting.

4) Recommended player e.g foobar, itunes, etc

I prefer Winamp (many plug-ins, and support for watching movies), and Foobar2000, and the ubiquitous iTune since I have to load music to the Ipod ....

My next upgrade is to source for a good power supply and I consider current offer by NuForce is not good enough.

Went to Darthfunk's place over the weekend to test the icon with his speakers. Haven't tried more speakers with it, but feel that my JMLabs speakers are a good match for the icon. Front-ported so you can slot it in near to your bedroom wall too. Forward enough so that the sound doesn't sound too recessed.

Bi-amping makes it sound better. Highs were much better controlled and thus less harsh. My set was also noted to be smoother due to run-in, and we noted his new set suffered some problems running his speakers (83?db?).

Went home, tried the 2m audiophile cables.. actually don't really feel it sounds much different than the 1m default cable. :) Can't do A/B on this.

I have used better alternative power supply on Squeezebox 3 and I have good results

Warranty issue when used with other power supply has been noted but it's not a big issue.

As Icon is not a main system for me and I would not consider bi-amp as it will make the desktop more messy.

Again depending on usage, I'm happy with my current setup which is either through USB with the PC or with my Iriver MP3 through
3.5mm jack.

My KingRex PSU just arrived and it is impressive and well made.  No modification and just plug and play.

I like the detachable DC cable and it has better grip with 2 pins at the middle.  As always the case that linear power supply is better than switched mode type that come with the Icon.  As KingRex PSU has been used to pair up Trends Audio T10 & has good results & I don't see why it will not be in this case for the Icon.

I think definitely it will improve the perfromance of my little Icon and meanwhile, I will just enjoy my music!!!

I see that the S1 speakers are about $400. That's pretty hefty for a desktop speaker with no crossover electronics. That means that it's only goal in life is to mate with the Nuforce Icon amp. If ever I want to change the amp, the S1 has to go as well. That's $400 down the tube and the person who wants to buy it used, must have the Nuforce Icon amp as well.
Pretty nifty marketing strategy. Think I'll give this a miss because mix and match functionality is more important to me than sound quality. I've no doubt the sound quality of the S1 is excellent, but with a package deal (amp + speakers) approaching $800, that's pretty steep for a desktop system considering the alternatives out there.
Might consider the Icon though, sigh.... I'll be paying for something I don't use, ie. the electronic cross over.

I guess NuForce has provided users an option to use the S1 speaker but not necessarily so that we have to follow.

IMO, being an audiophile you got to have freedom of choice and that's what Hi-Fi is all about.  End of the day, you must be happy with your choice.

The investment is only a few hundred $$, some household electricity monthly PUB bills are already more than that with rising oil prices.. and the amount of anguish it seems that some users are facing on deciding to whether own the little icon (just because it's over-designed to cater to S1 speakers) sounds so calculative.On the other extreme,  we have strange people who can spend > 25K to buy speakers but then look for the cheapest Ikea chopping board as speaker platforms, but here we have people who makes such a mountain out of a molehill of owning one of the least expensive class D amp with built-in USB dac as though they just emptied their money vault to buy a BMW...  ;D

I think budget and priorities can be v different to each person, so don't want to generalise that much on that.

Despite the 'audiophile' tag, I'm not sure the Icon is really meant for pure audiophiles.  We mustn't forget its meant to be a mass-market PC speaker, and most PC speakers are packaged with amp and speakers together for ease of setup for the general public. Even though I've not heard the S1 yet, I don't think $800 is going to be too much, even when considering the alternatives.

Personally I also buy alot of things that I don't use fully. Buying a TV but not using the tv speakers is a good example (i wonder who in this forum does). But what's important is if it fits your use the best among all the available options. Chances are we would be paying the same amount for a niche item of the same quality as the margins would be thinner for the manufacturer, even though we would love to ideally think that we can save cost on the components we don't need/use.

Title: Re: NuForce Icon owners / discussion thread
Post by: Darthfunk on June 16, 2008, 20:57
IMHO the Icon is design for desktop usage or as a 2nd system in the bedroom, kitchen etc. It is great for what it does as a multi functional class D amp however dont expect it to perform like a Ref 9 V2 SE amp.

Unless you dont have a matching pair of speaker, the S-1 is a good option to mate with the Icon. Anyway you can always use your existing pair or find something else to match it with.

Chances are we would be paying the same amount for a niche item of the same quality as the margins would be thinner for the manufacturer, even though we would love to ideally think that we can save cost on the components we don't need/use.

I recently got the components for a bedroom system, ie. speaker, DAC (with headphone amp), amp for about $800, which is about where Icon + S1 would be. However, I think going the seperate route is a better deal.  My last system which consists of an active speaker, went down and I'm left with a useless sub, sat and amp. I'm hoping with seperates, replacement will be easier and it leaves me with lots of room to try out new dacs, new amps, or new speakers whenever they come out.
So from the viewpoint of mix and match,  the main criteria for all my components must have standard interfaces, ie. RCA connects for signals, speaker binding posts, etc... The Icon with it's RJ45 connector would make it difficult to try out new speaker cables, or use existing cables, same for the S1.  Even the XLR connects would not be termed mainstream, unless all your equipment are balanced, and very few people are in this category.

Sure there are ways to get around this, with adaptors, but this adds additional complexity to the system and in audiophile land, we know that "simple" is good.

Care to share what did you buy? Are they all 1st hand?
Title: Re: NuForce Icon owners / discussion thread
Post by: khewa on June 21, 2008, 13:11
Amp - Trend TA-10.1
DAC - Fubar III
Speakers - Travagans 3"

they are all 2nd hand, but less than 2 months old. So to me, as good as new as the warrnty is still valid, except for the Trend which was about a year old. Currently trying out some speaker cables and interconnects. The speakers has the biggest impact on the sound, it steers the direction in which you want the sound to be. The rest of the components enhances the character of the speaker, kinda like a beautiful woman with makeup on, however, even without the make up, she's still a beautiful woman.:)
I must say though, purely from an asthetic viewpoint, the red Icon would be a very good match for my red Travagans. The silver Trends is just so blah.

Considered the Styleaudio Carat DAC, but the headphone amp just can't make it, not enough gain even at 3 o'clock, with the Fubar III, I never go past 11 o'clock, and if you need more omph, there's always the high gain switch. Currently using high gain setting for my speakers, bass seems tighter and stronger in this setting.

Of course, with the Travagans, I can easily pair it with another new fangled T amp, if ever that comes up. With the S1, I'm tied to the Icon.

I've a Naim system in my living room (Naim have their proprietiery DIN connectors, no RCA stuff for them), and based on experience, don't get a system with proprietery connections, it forces you to get the entire system from them for optimum operation, and then they bump up their prices for their components cos' they know they have you on a leash. I'm all for open systems and increased competition.

Glad you manage to find something u are happy with khewa.
Would you be open to doing a mini shootout vs the Icon + S1 when it arrives?
I've not heard the Travagans before, which you could also pair the Icon with.

The travagans ($408 new?) are similarly priced to the S1, so i think that would be a fair comparison.

Yes, the 3" Travagans are priced in the same region as the S1.

I'm out of the country most of the time though, only 30% of my time is in Singapore. Let me know when the S1 arrives though, I'm curious how it sounds. If I'm around, I'll be there.

I'm using the  Nanotec Systems' Golden Strada #79 nano3 speaker cables with my Trends amp. The sound is sweet. Tried the Belden 1313A speaker cables and while they are very clear, they were too bright for me. Still in the process of burning in the system, but already I can hear the potential.

I'm sure the Icon would mate very well with the S1 since it was designed as part of a system.

Hi medeamona welcome to XP  :)

Although 8ohm speakers are recommended to go along with the Icon, the Icon can be use on 4ohms speakers. I have even paired it on hard to drive speakers like the M&D Sapphire's and Mini's. Hope this helps.  :)

currently I am using Icon to drive 6.5" Hitachi fullrange speakers and the sound is sweet and the soundstage is deep and wide.

now i am happy with that gear. in the future, I am planning to have bigger size fullrange speakers, like 10" or 15", so the bass will be greater, haha

Hi Kent yes it function as a DAC and you can connect to your motherboard usb.
For $300 there are quite a few entry level subs you can find. Drop by City Electronics, I remember seeing a couple of entry level sub on sale around this price range.
You can connect the sub to Icon lineout.

There is no MO at the moment however you can contact SLT Tech to purchase the Icon and S-1.

Hope this helps  :)

The designer has already stated here...the S1 is designed to give a good 100Hz instead of a muddy 80Hz...

Base is not low...but the mids are sweet.  Unfortunately, I have been pampered by iPod through a 12" svs sub in my car, so find the missing bass makes the music reduced in scale tremendously.

You can use the PC USB out which the Icon will act as a DAC. What speakers are you using? If they are active speakers just line out from the Icon and connect to the sub.

When you say, PC USB, does it mean the USB from the motherboard? So no connection needed from the SC anymore? Sounds great!  ;D

I actually sold my PC speaker few days back so i don't have speaker for my PC right now, just a simple headphone. So i have two options now, buy Icon amp and use a spare unpowered speaker (clip speaker post) or buy Sonic Gear Apocalypx A8x (comes with a speaker + vacum tube amp - 2 x 25 watts rms).

Now i'm confused. Btw, both options cost S$250  ;D

You can use your existing speakers and connect it directly to the Icon.

Quick question, thinking of getting Icon + used cheap bookshelves as Xmas present for a friend. Deciding between Wharfedale Diamond 9.0 and Q-Acoustics 1010 (not 1010i). Any recommendations? Hard to audition cos I dun have the Icon at the moment, and I need to get them by tmr before my friend leaves the country.

Advice much appreciated! Thanks!

Hi Jonlee. Sorry to OT. You mean SVS has a sub woofer for cars? I am thinking of getting a sound system for my new car.  :)

Car sub woofers are mainly passive sub woofers. 

I bought a NSD woofer from a member, customised a box, scew in the woofer, connect to amp = 12" SVS NSD sub woofer.

Wow ... can I be your friend and get a xmas present as well?  :)

If I am not wrong, the 1010 should sound a tat better then the 9.0.  I think looks wise is also better?

ha ha, dun worry, gahmen should be giving out presents in the next Budget. Anyway, not sure if my friend will thank me eventually. Poisoning him with hifi, haha. Slippery slope for him after this.

thanks for the tip on the 1010. He only has cheap Sony ipod dock now, so Icon + decent bookshelves should sound good to him. If not, I'll ask for the Icon back!   >:(

I've got the Nuforce amp for several months now. Quite impressive for the price. Recently, I got my hands on a pair of Accostic Energy Aegis One bookshelf and an entry level Denon CDP with Kimber PBJ.

After listening to it for some months now regulalry, I have to say this amp is really impressive for its price.

Almost all of the CD I've played , the amp pushes out fine details with good clarity. Many occassions I played it loud till 1 to 2 o'clock, man... there is no distortion what so ever.

Talking about value for money, this is quite a star.

Hi guys,

For the record, this is not a sales pitch. I'm also a proud owner of the Icon.

I'm running this baby now with a pair of Waterfalls Victoria floorstands. One word - effortless.  :o

For anyone interested to hear them, do drop by my showroom.
For those who already owned the Icon, hearing this would only reconfirm the correct decision.
And for the uninitiated, hearing this will leave your balls tickled.  ::)

Hi all,

I am thinking of getting an icon to drive my Scandyna Minipods, wondering if its enough power to drive?
The minipod is rated at 90db spl (1w @ 1m) 4 ohm and Compatible with amplifiers from 10w - 100w output.
The source will be my trusty IMAC USB mainly for lossless music files.
Looking for some good/bad comments before i plunge...

Thanks in advance for any inputs..

Cheers

Post by: patrickx on April 20, 2009, 11:16
Hi, all I can say is Icon will have no problem driving the Minipods, especially if you
are setting them up in a bedroom space. Even then, there is the optional higher power
supply (45W) should you have a bigger space.

Maybe some of the owners here who have heard this setup can help.

Cheers
Patrick

Well, 90db bookshelf speakers should be no problem for the icon.. but it is 4ohms?
Title: Re: NuForce Icon owners / discussion thread
Post by: patrickx on April 20, 2009, 11:33
Yup no issue, not suppose to release this soon but since you ask, I'm running the mHi Evidence (90dB, 4ohms) now
with the Icon. Effortless.  ;D

Hi,

Thank for the advise, that's great as
its just for a small computer corner....

Just hope the sound amplified from the nuforce will not tend to be too bright sounding on the MiniPods.
Time for a trial i guess.... :)
Cheers

Just FYI from a previous user, the nuforice icon tend to be on the warm side, so don't think it will sound too bright. :)

Yup it is, closer to the warmth of neutral.

Though I am very familiar with the Minipods (ex-KEC), I have not heard the pairing before so will not pass any views on that.
Have fun auditioning.

if i'm not wrong.. dun think its possible to use it a pure pre-amp, since there is only powered output.
but you can use it as a pre/power since u can input a few devices to it.

Hi likchan,

The Line Out can be connected to an additional power amp or amps. In this mode Nuforce Icon can be used as an USB DAC or preamp.
Turn on the Icon with the volume at MINIMUM before turning on the power amp. When turning off, turn off the power amp first before turning off the Icon.

Hope this helps.

Cheers
Patrick

hey, guys,

I have used icon for one year and now am thinking about connecting one power amp to it.

Anyone has tried this?

Can I use the 3.5mm pre-out and use the 3.5mm--RCA cable connected to one power amp==>speakers?

so that we can have more choices of speakers.

thanks in advance!

Okay anyway visited AudioIconic for 2 demo session -
*plug*
Superb service by the way even when i haven't bought anything yet, nice and patient guy.
*/plug*

I have dilemma with this Icon/S1/W1.
I like the integration/dynamics/clarity/details but there something nagging in me that unsettling.

Apparently with music I listen to - King Crimson/Dream Theatre all the way to Acid jazz and Jazz rock fusion kind of genre.
It seems that FR doesn't seem to capture my attention, with much of my analysis that FRs are meant to be laid back and more for vocals only kind of music.
The feeling is there but yet not there, where don't feel musicians rocking it out infront of you.

It is within my budget to get the whole suite and i'm like 80% firm into buying, somehow 20% is feeling something missing that lacks the thrill of the music.

I feel bad after such good service and patience by audioiconic to not get it from them.

So can anyone point out to me a good fit within that budget if i could just get Icon only but also want some bass?

switch the W1 with a Velodyne SPL-800i - Subwoofers and try.
Title: Re: NuForce Icon owners / discussion thread

Yes. I'm using the Icon with Velodyne SPL-800i and it's good!!

Title: Re: NuForce Icon owners / discussion thread
Post by: Quest on June 19, 2009, 09:51
Well, this is just my opinion.
I really like the Nuforce icon when I had one, but I feel not everyone will like the S1 and W1.
Nuforce has their own sound character in mind when they made the set.. it actually sound similar to their earphones.
If you don't particularly like the combo but like the icon.. can consider buying that first and then auditioning it with other speaker or even sub combo.

I agree Patrick gives good service too. :)
Title: Re: NuForce Icon owners / discussion thread
Post by: jonlee on June 19, 2009, 10:10
I have not headr the W1 before, thus cannot comment on that.  I do like the sweetness of the icon + S1 (did not bother to do rta, just trust that the OEM did equalise the pair).  Vocals sounded very sweet.  However, really could not tahan the total lost in bass.  Rearranged my whole study room to relocate the S1 to be against the wall, still no bass.

Added 800i...happy liao.  :)
Title: Re: NuForce Icon owners / discussion thread
Post by: Quest on June 19, 2009, 10:24
Good to hear you like it jonlee. :) I personally find the S1 really too lean for my liking, even though the output was very clean and overall tonality quite neutral..
Title: Re: NuForce Icon owners / discussion thread
Post by: myhifisystem on June 21, 2009, 11:26
I have the ALR Jordan Entry S which goes along well with the Icon and of course Velodyne SPL-800i. The other thing you can try is to improve on the power supply, try the KingRex SLAP and you will never regret!!

Regards
Title: Re: NuForce Icon owners / discussion thread
Post by: weibchen on June 23, 2009, 23:46
Correct me if i'm wrong, the sub connects to the Line Out right?
BTW how much is the Velodyne SPL-800i If any kind soul can tell me.
