jeffmudrick Posted January 11, 2016 Share Posted January 11, 2016 The way I read it was that they're just not going to get MQA certified for it unless there's a DAC involved. E tu Bluesound ?? Link to comment
kennyb123 Posted January 11, 2016 Share Posted January 11, 2016 I wonder if Auralic got the MQA code from Meridian for their DAC(s) and then decided to incorporate it in 'all their products' without getting an approval first? As a partner they were likely provided an SDK with functions they could incorporate into their code. They obviously went ahead and did that. The issue here is whether that implementation will earn them the right to call their product MQA certified.

Jimmypowder Posted January 11, 2016 Share Posted January 11, 2016 Thanks! Bluesound doesn't' look like a dac to me but someone posted their interview here about MQA and Bluesound integration . Am I missing something or do their devices have a dac ? Link to comment

Jimmypowder Posted January 11, 2016 Share Posted January 11, 2016 Bluesound would have same issues as Auralic. Well The Bluesound owners really hyped the integration of their products with MQA in that interview . I guess they thought they had a deal too with Meridian or am I wrong about this ? Link to comment

monteverdi Posted January 11, 2016 Share Posted January 11, 2016 I just downloaded a sample file from 2L and it was showing up on Audirvana+ as 24/44.1. So one can claim better than CD but just barely. I have not listened to it yet. I also looked at pricing for downloads on the 2L website for a recording from them I really like Joachim Kwetzinsky POLYPHONIC DIALOGUES: Shostakovich - Shchedrin. 44.1/16 14$ 96/24 19$ MQA 24$ So why would anyone be interested in MQA if it would only play on one's DAC at close to CD quality. I understand the statement end to end for MQA. I am wondering wether any DACs presently owned by customers will be ever able to use MQA. Even if some companies have signed up for MQA it does not mean they can or will do a upgrade for MQA for their current or legacy DACs. If only a firmware upgrade is necessary I could see it happening. Link to comment

Thanks, then I hope this close the discussion about if you get 16 or 24. However what seems strange to me is that the recording from 1993 with that DAT is also 24 bit. Could you download and verify as well ? Carl Nielsen: Chaconne op 32 Christian Eggen http://www.lindberg.no/hires/mqa/2L-120_01_stereo-44k-24b.mqa.flac As far as I understand that file should be 16 bit, as the original is 16. http://www.lindberg.no/hires/test/2L-120_stereo-44k-16b_01.zip Link to comment
matthias Posted January 11, 2016 Share Posted January 11, 2016 IMO, they upsampled the original file to DXD and converted the DXD to MQA. Matt "I want to know why the musicians are on stage, not where". (John Farlowe) Link to comment
crenca Posted January 11, 2016 Share Posted January 11, 2016 Thanks, then I hope this close the discussion about if you get 16 or 24. Probably not. For example, you can encode an 8 bit file (or an mp3) into 16, 24, or anything you want. The question is not file size or how software/hardware that expects standard PCM encoding (such as Audirvana) reads an MQA file bit depth, but what is actually useful to a standard PCM DAC, and to answer this question you have to comb through the marketing/product speak of Meridian, look at Miska's work, etc. Hey MQA, if it is not all $voodoo$, show us the math!

esldude Posted January 11, 2016 Share Posted January 11, 2016 I have checked this 2L file with two pieces of software. It is of course 44.1, and is 24 bit. The lowest bit value in it was actually one step above the LSB at -138 db. According to the VST plug-in Bitter from within Reaper, it is 24 bit. Exporting samples using Audacity you have plenty of sample values in the lower few bits of a 24 bit signal. My guess is like someone said, was upsampled to DXD and then turned into MQA. Upsampling would have included some dither of some sort which fits with the least value being one step above the LSB. This file also has very low levels of signal in the upper frequencies even in 44.1 khz form. Otherwise this thread seems to have spun off its axis, left the rails, gone astray. And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality. Link to comment
DanSmedra Posted January 11, 2016 Share Posted January 11, 2016 Brilliant analysis. (Of course I was being sarcastic) There will still be a benefit from the compression and thus it will still be possible that TIDAL will stream high res. A big benefit to subscribers who care about sound quality. The announcement pertains only to achieving MQA certification. A streamer can still be able to decompress MQA. +1 Source: TIDAL HiFi/Masters, Pandora One > iPeng 9.2.1 on iPhone6s/iPad Great Room: SBT#1 > Cullen Coax > PS Audio DL3 DAC > Audio Envy cables > Martin Logan (ML) 200Wpc Purity.

No chatter to support that theory at this point. Link to comment
krk4201 Posted January 11, 2016 Share Posted January 11, 2016 guess it would just be like the Aries Mini where the streaming devices are MQA certified for the Analog outputs but not the digital ones. Ugh. What a mess. Link to comment

MQA has not yet completed finalizing the definitive version of the technology; no MQA partner has yet to receive the actual final version of this emerging technology, which will be downloadable to any product in the very near future.)
