Wow, sorry you're going through all that.
It's pretty surprising, given PS A's reputation.
I was in the beta program, ready to purchase a beta unit when Covid shutdowns drastically cut into my income, forcing me to re-think spending a couple grand on something I didn't absolutely need.
A year ago I got a Parasound NewClassic 200 Integrated and I've been totally pleased with it.
Totally shocked at all the bugs you report and even more shocked by your firmware date. May 2020 was in the middle of the beta release. Does this mean it's been out 18+ months and the beta firmware is all that is available?
Hope PSA gets it's act together soon!
Maybe you should write to "Ask Paul".
Good luck to you and thanks for the "heads up".
