I have owned an A21 since January and only heard it through my Martin Logan speakers, so cannot compare to other amps/speakers as others here can. I can say that my amp does not run hot . . slightly warm only . . but I have it open to room air and would recommend that.
For that price range, Parasound has an updated model with more power, the A21+, which might be a better comparison to the other models you are looking at. Normally $3,000, I’ve seen the A21+ on sale recently for about $2,500.
