The problem is, MQA is not a "format". FLAC is a container for audio that uses lossless compression. MQA is a method of lossy audio compression.
Saying "I love how it sounds" doesn't have any meaning. You're not "hearing MQA" but hearing the music after it has been processed by MQA. The problem here is: What music? How it has been applied to old and new music, and even some particular albums where the process was done carefully by an individual using their tools, is often quite different. I found it butchered old music, for example, and wrecks classical. The 3D-plug-in-like effect on modern music is arguably nicer in some ways, but sounds weirdly mutated through some DACs.
I think that for certain people who like certain types of recently recorded music with MQA-compatible set-ups it will be enjoyable, so keeping the focus on discussing what music and set-ups work optimally with it is a better idea.
