MQA never was welcomed in this house of stereo. I also dropped Stereophile and TAS subscriptions in part because of their sales pitch for it. Don't mess with music signals, lesson learned.
I never got into MQA after reading a paper on it by Bob Carver where he said at best it did a little of what his old sonic holography did (eliminate crosstalk) to better position instruments and voices in the soundstage, but at worst, in later iterations, it didn't even seem to do that. It was a lossy method of slight compression that might have been needed and helped when not everyone had 100Mbps (or higher speeds) Internet. But now? Not so much. It was an idea whose time has come and gone.
