I really enjoy a lot of music at 320kpbs MP3 encoding. What's your point?
There is a big difference in enjoying MP3 (a known to be quit a bit less SOTA that the average human can hear.) (there is a lot that I enjoy that is not SOTA).
But claiming that one can hear MQA files better than other formats, without scientific proof of that, well, lets just say that is just not going to fly as beleavable among most folks here.
Of course, there can be eceptions, but proof is a necesary attribute.
EDIT: If he just said that he enjoys it or that he prefers it, I'm good with that.
As to Championing the format, is that a paid endevor or is he Championing the format becacuse he prefers it??
There is a difference there.
But most that have heard it disagree & the scientific proof that it is better does not seem to be there.
In fact, there is a lot of proof of the oposite.
So, unless he has something new to add about it...it is basicaly dead.
Unlike vinyl, which people (me included) like (despite/because???) of it's well known & admitted flaws.
