Parasound A21+ or PS Audio S700 monos?

Since I have the time, I ordered a pair of M700s (the fact they are made in the next town over is a positive!).  Should be here in a week or so.  The promotion ending today made that decision easier . . .

May also try a A21+ as several people have said they think they'd prefer it.  And if a Belles comes up I'd be inclined to buy it to try out. 

Other input welcomed!  I'd also be curious to try something like a Krell KST-100 - funny that a KSA-100 Mk2 is only $20 more on a well-known used dealer site!

@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 . . .

Hmmm . . . M700s now delayed until May, date unspecified. 

May have to consider Belles Arias . . .

Or a Belles 350A Ref, which should be on the way shortly.
