In Reply to: RE: best MQA Tidal Explanation I have read so far posted by bullethead on January 12, 2017 at 04:25:04
At least as it was explained by Meridian's Bob Stuart at the 2015 RMAF when he says:
"Tidal's desktop app (Mac OS, Windows) will carry out the first unfold, even in the absence of an MQA DAC. In other words, a 24bit/48kHz MQA file streamed via the Tidal desktop app will reach the downstream DAC as a 24bit/96kHz file, whether that DAC is MQA-certified or not. And if the original studio master has a sample rate of 96kHz or less, you're not missing out on anything."
But then admits: "Actually, no. ANY DAC can play it. It just won't see the entire hi-res portion of the file that MQA's encapsulation has tucked away under the file's noise floor."
I seem to recall Mr. Stuart saying he didn't think we really needed all 24 bits (below the noise floor) so he used them do encode the extra samples between 48KHz and 96KHz and that why some still call it a 'lossey' codec.
But I could be wrong.

I get the impression from a couple of the reader comments posted on Mr. Darko's page that "lossy" is immediately thought of by some folk as being synonymous with "frequency loss". As has been the history of MQA to date, prejudice coupled with little desire to find out the facts.
There still appears to be a lot of speculation and confusion surrounding MQA.Right now MQA seems like unnecessary smoke and mirrors with lots of complexity wrapped up in great marketing spin. The next new thing for audiophiles to play with and the founders to profit from. Next.
Even if MQA offers outstanding results, I'm not sure how it will benefit ME. I have thousands of music files already ripped or downloaded that sound outstanding on my present equipment. I'm not likely to repurchase my music in MQA.
I suppose if I were to subscribe to Tidal it may be beneficial for streaming.
Until MQA goes more main stream, I'll sit on the sidelines as I often do as I am not an early adopter. But I'll probably give it a try someday unless it dies on the vine.
What ever happened to Pono? Still under construction? ;-)

I'll be retired by then. :)
I've been meaning to post an update on Pono. Tonight I will start a thread on hi res. I received an email from them, and I want to reread it before I post.

Big speakers and little amps blew my mind!
Interesting. When the Pono service went down they were talking about rebuilding it but that was quite a while ago. Please update us when you have a chance.
Who knows?
But if you start with 24/96 music and end up with 24/96 where the last four bits are 'zero' because you used those four bits to carry information between 48Khz and 96KHz, one COULD safely call such a codec 'Lossy', 'Lossey', or even 'Lossie'. ;-)
Woof, woof!!!
