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?

My anti-fans will remember I made a mistake, while my fans will remember I corrected it.
Erik, have any of your "fans" asked for autograph? LOL

@tweak1 There might have been an issue with your A23, my A21+ runs warm but never hot and my speakers are not that efficient. I have 5 amplifiers and I hear a difference in the sound produced by each of them.

Hello naimfan,

I think the A21 is a very good class AB amp but still think the S700s will equal or surpass the A21 in every single facet except price, size, weight, electricity consumed and excess heat produced. The A21 may be able to handle 2 ohm speaker loads better than the A700s, which is a strange and meaningless advantage to mention considering your speakers’ impedance never dips that low.
The S700s will have a much more neutral sound quality than the A21, which adds an intentional warm quality to the sound. Of course, it’s your decision which overall amp quality you prefer.

Best wishes,
Tim
