Charles, very interesting. A poster on another forum had AMAZINGLY similar listening impressions to yours. (SUBJECTIVE listening comments in your post)

"I heard a very hi-end demonstration of MQA about a month or so ago in NYC. Peter McGrath did the demo with his own recordings (24/96) that had been MQA processed. We had a chance to hear the original and then the MQA version. The setup was as follows: Wilson Audio Alexx speakers, top-of-the-line VTL preamp and amp. and Meridian DAC (of course). The music wasn't what I usually listen to, however, the difference was very clear to everyone in the room (including Michael Fremer, who was seated next to me). I expected to hear equivalence (i.e. that MQA had done no harm), however, there was clearly a difference. The MQA sounded somewhat brighter and had more presence! It reminded me at the time of the "loudness button" and old amps that I had 30 years ago (I had not seen the May 2017 Stereophile at the time of the demonstration).
I managed to corner one of the MQA guys who accompanied Peter and after some prodding by me he explained that they do DSP of the signal as part of the MQA encoding to "make it sound better". While he did not go into any great detail, he indicated that things are done to try to reduce pre and post ringing that are present in almost all digital audio signals. I can only speculate that this involves some kind of digital filtering of the original signal.
Based on this one demonstration I certainly would not advocate for spending time and money on MQA (and risking falling into the clutches of Meridian). Since my preferred digital is SACD I do not see any need for MQA and I certainly do not want anyone using DSP on my digital data streams to make them "sound better"
If I had been able to vote I would have voted for the following:
I won't use it as it doesn't offer me anything I don't already have
I think we have sufficient formats to manage high quality audio already
I think Meridian are focusing more on creating a revenue stream."
