Personally I consider your argument a non issue as I feel you have missed the point of MQA entirely.
MQA sounds great, undecoded, half decoded and full decoded in my experience and one advantage is the servers will only need one source file to cover all bases.
I appreciate the anti MQA lobby hate this idea as much as I hate Brexit, but it’s a tough world out there and they may just have to ditch Tidal on this issue.
