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?

@j-wall What are you using for a Pre-Amp? Synergy is important and I had the Simaudio 390 as a pre. 

BTW there is no humidity in TX.LOL.

I am all tubes now. 14 foot ceilings help though and a kick ass AC System that is balanced.

I'm using a Primaluna Dialogue Premium Pre. 

And really no humidity in Texas? My time in Galveston and Houston there was quite a bit of humidity, but sure lol. 

Yeah I'm upstairs. We have 24ft ceilings so all the heat rises into the rooms upstairs so the AC tends to cool downstairs a lot easier than the upstairs. 

I've considered PS Audio M1200's and Atma-sphere Class D's but not sure yet with the class D stuff.

I've owned the PS Audio M1200's - I really liked them.

@sdw would you say they compete in their own way with the A/AB stuff? What did you like about them?

@j-wall I like they had effortless power - 600 watts per mono block. You won't run out of headroom. In my specific circumstance, given the speakers I have, they were a little more bass centric than what I ultimately ended up with - PS Audio's BHK 300 mono blocks, which are AB. Depending on your speakers, the 1200's could be an excellent choice.
