I've generated a new Tidal Masters MQA spreadsheet with 3315 albums.

I was pleasantly surprised with the MQA list when I saw it while taking my bus home yesterday.  These are exciting times.  Thanks Wklie.  Will you be around at the Guangzhou show, 2 weeks from now?

Hello
I have updated the Lumin U1 for mqa support
Some things to share :
My system for listening the mqa via tidal is as follows :
Lumin U1 is connected to Chord Dave via AES EBU . The U1 is connected to my internet bow via RJ45 + network filter . The U1 is also connected to Melco N1A via Ethernet RJ45 + filter . The melco stores my music
The Lumin + Melco +DAVE are filtered via the excellent PLIXIR BAC
Listening is done via Focal Elear earphone via DAVE
Album tested is Marvin Gaye " What's going on "
44.1 flac, and 196 flac are stored on the Melco
Tidal streams 44.1 , and the 196 versions
Conclusions (FOR ME)
1. The flac in the Melco and the one from Tidal MQA , sounds the same (both 44.1 and 196)
2. The HD version sounds better to my ears than the CD version

I have been a MQA septic , because I like to buy my music
However , it's more practical to have Tidal (albeit being dependant on inibternet)
Lastly , I should state that LUMIN has been of tremendous support , and the Lumin app on IOS works really good
When I see the difficulty of having DSD files , and the easiness to have MQA high res files , I guess that mqa will be a good streaming format (even if there are loads of septics like me)
I wish to express my thanks to wklie for his support
Cheers

Hello
futher listening sessions confirming the above impressions
However , it would be interesting to compare with DSD format
Why has DSD not taken the rise ?
It seems to be that SOny is one of the major promoters of the format, and one of the major production company
Cheers

Hello
Following the mqa compatibility
1. I understood that the U1 is just unfolding the mqa .. but the Chord DAVE does not decode MQA .. is there a big difference ?
2. A new firmware is out for the U1 , do I have to update ?
Cheers

In a Lumin U1 + Chord (or any other non-MQA DAC) configuration, Lumin U1 performs the MQA Core decoding to 96 or 88.2kHz so you get Hi-Res musical content.  The lack of MQA in Chord means that you do not get the DAC-side deblurring offered by MQA.  This is case B in this article:
https://www.computeraudiophile.com/ca/ca-academy/mqa-for-civilians/

With a MQA Full Decoder to analog outputs, i.e. Lumin S1 / A1 / T1 / D1, MQA is fully decoded and DAC-side deblurring is applied.  This is case D in the above article.

The public U1 firmware does not support MQA Core decoding yet.

Thats great to hear that all the Lumins areMQA compliant.

In your opinion, with the other lumin full mqa decoder, how much more does one get with full mqa over core mqa decoding?

High end DAC manufacturers are avoiding MDA because of politics and because it is a lossy format.

The exceptions are MSB and Bekerley....and of course Lumin...  :)

Chore Dave doing MQA, I think unlikely....just be like me, buy a Lumin exclusively to play MQA....just a D1 will do.

It has been recently reported that DAC manufacturers wishing to get on the MQA bandwagon have to hand over the design/workings/etc of their products.

And to assure other DAC makers that there is not a lot of incentive for him to do anything with what he learns, Bob Stuart recently divorced himself officially from Meridian (as of 4 September 2017).....

Technically, full MQA decoding unfolds to higher sampling rates, whereas Core decoding is always 96 or 88.2kHz.

Subjectively, digital harshness is further lowered.
