Hi Brian,

most of the stuff I have to offer on MQA is probably nothing new to you but here we go:


The Hifi-company & record label Linn has published an open letter on MQA which should be read by anybody working in the music industry:

Andreas Koch who worked at Studer & Dolby, was part of the SACD-team at Sony and now is an OEM-designer of DACs at AK-Design has given a clever interview on the topic:

MQA


The most up-to-date discussion and technical analysis of MQA happening on the Computer Audiophile Forum. It sometimes get's lively there but overall keeps a good S/N ratio:

Look especially for posts by Charles Hansen and by Mansr on ca. the last 5-6 pages of the thread. Earlier in the thread (pages 120 up) there are also interesting contributions by user Soxr.

Charles Hansen designs electronics incl. DACs for the hifi-company Ayre and talks shop on MQA as well the audiophile-hardware industry in general. Some of his claims are to be taken with a grain of salt but it's absolutely read-worthy stuff. His posts start at page 146.

User Mansr has done work de-compiling MQA. Same with Soxr.

Belgian audio-programmer Frederic Vanden Poel has gone public with his critique on MQA here:

KIH #46 - MQA's missing link? | DAR__KO

This was also discussed on Computer Audiophile in another thread worth a look:

It might be worthwhile to get in touch with Ebean from the 6Moons website too.

Blogger Archimago working closely with aforementioned Mansr has an MQA listening test up and is a very knowledgeable source on MQA:

Archimago's Musings: INTERNET BLIND TEST: MQA Core Decoding vs. Standard Hi-Res Audio

Audio software vendor Xivero published a technical white paper on MQA available here:

https://www.xivero.com/de/hypothesis...y-mqa-limited/


All of the above is more recent. Looking back to 2016 there were two important public statements on MQA.

DAC manufacturer Benchmark to my knowledge was first out of the door with their critique on MQA:

https://benchmarkmedia.com/blogs/app...855-is-mqa-doa

Followed up by hifi company Schiit:

Schiit Audio, Headphone amps and DACs made in USA.


An up-to-date list of audio hardware/software-vendors who have expressed concern about MQA would be nice. By my own count these would be:

AK Designs (DACs & software)
Ayre (Hifi)
Benchmark (DACs)
Klinktbetter (Hifi software)
Linn (Hifi)
Schiit (Hifi)
Xivero (Studio software)

Daniel Weiss seems to be on the fence on the issue, at least thats the gist of an interview he has given in Switzerland. Apparently Dan Lavry has spoken critical about MQA too but I can't find a credible source online.

As for the arguments in favor of MQA you'll find these easily peppered across the Computer Audiophile threads...
