I don't pay attention to reviews much anymore because they really don't tell you anything.  I have owned three different JC1 amps, one of them was brand new (and burned in 500 hours).  The A21 was also brand new.  I have owned a variety of different amps and have compared these Parasound side-by-side with other amps.
+1 on Belles Aria. Good fit for your requirements. Just reacquired one for my 2nd system.

+1 on Hegel as a bad choice. While I wouldn't call it warm (nor would I call Aria warm), I do agree that it’s overly damped & flat/dense sounding

(Have owned both).
