Any proprietary single-vendor locked-in technology is doomed to fail...

There still un-answered question whether MQA is truly a mathematically lossless codec when compared to FLAC?

Spot on!

On the question of lossless compression, IIRC it’s already been answered (indirectly) by Bob Stuart in the detailed ComputerAudiophile interview script…”Section C” in MQA’s origami fold is lossy compression. And he wasn't absolutely clear on section B either... I'm guessing the compression could vary depending on a number of factors.



IMHO, the whole compression issue around MQA is a waste of time... bandwidth (like HD capacity) is cheap these days... there's really no reason so spend so much effort with tricky compression techniques. How many people manually zip files before email? Hardly anyone does that these days. Likewise even for high-rez music streaming, bandwidth will be a non-issue.

Not everywhere in the world though :(

In larger countries rural areas get their nextgen broadband via 4G even at home and have a monthly cap not like the all you can eat style we have in Singapore.

True... but which do you think will come faster? Higher/adequate speed broadband to rural locations, or a full MQA catalogue (and with all the costs associated with that?)  ;)

Knowing Australia. MQA on TIDAL would be here sooner :P

I have seen some areas have an ETA on NBN in 2020. And my suburb - Not Planned Yet. Damn you Malcolm, worst NBN Minister ever.

Don't worry, Telstra will be rolling out 5G by 2018/2019; that'll get you 10Gbps (contentionless) peak-rates on your hand-held devices (though T may chose to engineer throughputs below that ;))

Yeah but at 50 bucks a month on a 1.5GB plan... how many HD files could I be streaming in full hires? :) my ADSL at work is even choking with regular TIDAL.

I'm pretty sure it'll come inline with the rest of the (leading) broadband nations soon enough... IMHO, 5G's going to revolutionize the broadband landscape in markets like Australia thats been languishing for so long  :P

Looks like anything above 22kHz is considered mathematically 'lossy' this is because the maximum MQA bit-rate is capped at 1.5Mbps.

WARNER MUSIC GROUP & MQA ENTER LONG-TERM LICENSING DEAL

Munich | May 6, 2016: Warner Music Group (WMG) today announced a long-term licensing deal with music technology specialists MQA. The agreement – the first between MQA and any major music company – will significantly increase music fans’ access to hi-resolution music globally. The agreement paves the way for recordings from WMG’s diverse roster of acclaimed artists and its world-renowned catalogue to be made available in studio master quality through MQA distributors.
...

Not a huge surprise considering Atlantic Records (one of Warner’s largest labels, wholly owned since ’67) has been a supporter of MQA for well over a year now.

Still, crap  >:(

So far only 2L, a Nordic Sound has released MQA tracks but limited genre...
http://www.2l.no/

Licensing deal is one thing but putting music on wide scale distribution is a huge challenge provided there are sufficient MQA hardware enabled devices to decode with, otherwise is just plain paper agreement. Nobody wants another loyalty paid DRM codec and ended up paying more.

There are already many loyalty free lossless codec such as FLAC, DRM free!!! which has a wide adoption.

Interestingly, the technology skeptic and critic Mark Waldrep (aka. Dr Aix) couldn't get a test sample from Meridian to do a thorough analysis

Mark is not a big fan on DSD either it seems http://www.3beez.com/video-introduction.html
I have a pile of stuff that pushes out squiggly waveforms from smaller squiggly waveforms that sometimes come from 1's and 0's.
It's wonderful to behold as long as you don't let the magic smoke out.

Life is short! Enjoy the music while it plays, when it stops, there might be a chair for you...or  maybe not.

Interesting piece by JA in the latest issue of Stereophile... First real measurements of MQA by a 3rd party AFAIK;
http://www.stereophile.com/content/inside-mqa

ps: Is it just me or does JA sound distinctly less "enthusiastic" on MQA then he did before? ;D
