MQA - Music Discussion

This thread is to discuss MQA music currently available, listening impressions, and how they were encoded.

Please keep tech. talk (except provenance) out of this discussion! :) This thread is about finding good music sources, listening impressions, and mastering. There is a lot to be said about the algorithms, hype, and politics but please use other threads for that in the Digital section perhaps. :) 

I'll start.  I know right now of only two big labels offering MQA:

2L.no (maybe only test tracks)

and

as well as at least one indie label. Thanks to Peter Veth over in the DAR thread here:

I'm particularly interested in talking about works we can find to do A/B comparisons with, as well as any tracks listeners feel are exemplars and say "This is good stuff!"  because so far I've had no luck at all.

As others know, the thing that has so far affected music the most is the mastering choices made by the engineers, as opposed to actual encoding technology, so I welcome details of that along with listening impressions.

Thank you.
