Simaudio 400m / 860A vs PS Audio BHK250


Any thoughts on the Simaudio 400M vs 860A? My PS Audio BHK250 is blasting me with heat and I'm looking for other options. My tiny room is 9 by 13 by 8 and is upstairs and south facing so it gets the sun and heat all day. Running the home AC will get the downstairs cool, but this room doesn't stay comfortable with the BHK running and is causing me to end listening sessions short and irritated. I'm not sure I'm open to class D since I'm not willing to have a bigger cash outlay for class D to try to hopefully get to an equal playing ground ats the BHK250.  

The Simaudio 400M runs cooler, but then again is two chassis so maybe not. I'm concerned I'll loose detail and sonics moving to a less costly amp. I'd love a 860A and know the sonics would improve, but according to Stereophile the fins get up to 110 degrees which would only be 10 percent cooler than my BHK 250 and I'm curious if I'd even notice the change. Thoughts and opinions?

Anyone listen to or own the Simaudio Moon 760A?  How does it compare to the 860 or the M400?  I know it has less power than either the M400 or the 860 but I think it would be sufficient for my Vandersteen Quatros.  I doubt if I want to spend the money for the 860.  A pair of 400s is about the same price as the 760A and that is a price range I would want to stay in.  Recommendations between the two?  BTW my current power amp is a Bryston 4bsst2.

Thank you all for your responses.  Just to add a bit of diversion to the discussion, has anyone compared the Simaudio Moon amps to Ayre?  I am also considering the Ayre VX-Twenty power amp.  It is similar in price and power to the Sim 760a.
