The question with MQA is it's staying power, not its technical excellence. It has a very tall hill too climb to become relevant. IMHO the only genre that really merits it is acoustic music, most of which is classical, and that genre is increasingly going to either hi bit rate PCM or 5.1 96Khz / 24 bit MCH (Blu-Ray). Many industry observers think it has already missed the window. I also agree with Erik, in that whatever MQA brings to the party, it is still a secondary factor to the quality of the recording and the mastering itself.
BTW, I like SACD and DSD, but the absolute best digital I have heard is Reference Recordings DXD which is 352 kHz/24 bit PCM. In addition, if your processor / DAC uses DSP's for room corrections or even digital reconstruction filtering, it will convert DSD to PCM before it converts it to analog. This is a buyer beware issue "pure DSD" DAC's which use only analog low pass filters for reconstruction are rare birds.
