Parasound A21+ or PS Audio S700 monos?


Since I have some time on my hands, I've been playing with my hifi.  And it's time for a new power amp.
Rest of system is an Exposure 3010S2 CD player feeding a Naim nDAC, an Exposure 3010S2 or Conrad-Johnson PF2L, speakers are Monitor Audio Gold GX300s. 

In looking and reading, it seems like the Parasound A21+ and PS Audio S700 are the leading contenders.  New S700 monos are $1798; a 1 year old A21+ is $2000.  

Thoughts on them?

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.
@feldmen4 - Thanks!  That's very helpful, as your speakers are pretty close to mine (or at least should be!). 

As mentioned above, I may just buy a used A21+ to compare to the M700s (incidentally, apologies to all for getting the thread title wrong).  And will entertain other amps as possible . . .
