I vote "Yes" for MQA: on Tidal, I find that most of the MQA versions of albums/titles sound better than the non-MQA versions to my ears. And, Yes again, that I view MQA as a way to get better sound from streaming, but not as a end-all format that replaces lossless files & SACD's that I have/will purchase/download.
In my view, there are simply no downsides to MQA as a streaming format. It is part of my Tidal subscription and a built-in MQA-capable DAC is a feature on my (recently acquired) Bluesound Vault 2. Put together with Tidal, this has greatly increased my enjoyment in listening. And, AFAIK, none of the doomsday scenarios have come to pass yet. It is still very much your option on whether or not to MQA. I suspect, if it ever does appear that the powers that be try to "force" it...it will be met with great indifference in terms of purchasers.
I get that MQA is not lossless. I get that it can be scientifically proven to be inferior bit-for-bit and measurement-wise to FLAC, DSD, DXD, etc. And, I completely understand from a recording pro's POV that MQA is not what they/the artist intended. But, I am not an engineer or scientist. I am a consumer of content, the end-user...I am the customer. And what I hear from MQA, for the most part...I like.
As others have said, cannot we just get back to enjoying the music, no matter how we do it? I really do hope so...
