@lonemountain , it must feel like you are a fly on the walls, nice to get the inside scoop. The problems you posted about atmos music applies to movies as well. You have great mixes and weak mixes. The best mix I have heard so far is the kraftwerk catalogue on bluray. At reference level it is a great concert mix. I really like the Beatles remixes too. I am using more Tidal to stream than apple music. Apple just sounds a bit bright for my room.
@mijostyn , if you like 2 channel all good, maybe you can send capitol record studios some pointers on their speaker selection. Who knows, maybe they’ll outsource a custom build for you!
I really like the flexibility to upmix certain tracks. Vinyl guys swap out cartridges=$.
Digital guys swap out DAC’s= $.
Immersive music guys push a button on the remote. Every recording can benefit from how it is played back in your room and you still have 2 channel as one of the many options.
It is a matter of preference and taste, not better or worse. One example that includes measurements and test tones. He discusses 2 channel music upmixing at 5:30:
