Parasound A21+ or PS Audio S700 monos?

I too was concerned about the A21+ and the heat but it never has gotten very hot, just warmish However I never drive it loud!

Hey naimfan - I have an a21+ powering a pair of Monitor Audio Gold 200 speakers. While I can’t speak to the PS Audio monoblocks, I am very pleased with my system. I stream through a Blusound node2 and also have a vinyl rig (Rega). I use an Anthem MRX520 as a preamp when listening to 2 or 2.1 channel. My next purchase will be a DAC to upgrade the digital experience. 
My a21+ does not run particularly hot - warm yes, but I’ve never perceived it to be heating the room. That includes during lengthy high volume jam sessions.  I bought it new a little over a year ago and have had 0 issues. 

bwaterme - I went back and forth between the JC1 and the a21+ and ended up with the a21+ to preserve domestic tranquility.  Based on your experience I guess it worked out ok. ;-)

You might want to look into a used Anthem P2 amp, plenty of power and able to go down to 1 ohm if needed, also even at ear splitting volume the amp never gets hotter than room temperature.The P2 amp is a very neutral sounding amp that neither adds to or takes away from the original sound of the music source.If you are near the Chicago area I would be happy to give you a demo listen.

Doesn’t ps audio offer a 30 day money back offer? Instead of relying on comments/opinions, bring the ps audio amps in for an in-house trial Using your equipment and if you don’t like them, send them back. I have heard good reviews on the 700’s. I have the ps audio Bhk amp and DS sr dac, and sound fantastic. Also with ps audio, you get very good support.
