Since I don't own an MQA-capable DAC, and refuse to spend $19.95 on TIDAL, I haven't checked out MQA yet.
Has anybody hear heard it, and compared it to CD standard 16/44.1, or better?
I'm not sure I understand the process involved yet.
No, I haven't heard it but flac seems to be a reasonable way to transmit internet files and home storage is relatively cheap for large files.....I'm in no hurry, therefore, to hear it.
There's a lot of controversy around MQA. I personally have no interest in MQA, particularly given that it is proprietary. Here's some fairly objective technical information if you're more curious: http://archimago.blogspot.com/2017/01/comparison-tidal-mqa-music-high.html
