Bryston 4B3 or Ps Audio M700 monoblock?

I'd like to replace my 20 year old Bryston 4B SST with a new amplifier, solid state or hybrid. I have been considering the 4B3 and the PS Audio BHK 250. Both got great reviews but I am a bit concerned about the midrange withe the 4B3 and I do not like the amount of heat that the BHK 250 is  reported to produce. I am thinking now of the PS Audio M700. These are efficient class D and do not produce much heat. The M700 has also been reviewed favorably. It's a stereophyle class A.
I appreciate any thoughts on this, an din particular if you have experience with these amps.

Thanks to all for very helpful information. I think I'll give the M700 a try. Thanks again.

reflecting on your comments, I am curious as to why you think I should not consider PS Audio (gammonit-2000)

To me Class D sounds just as good as the other classes, if done correctly, as with the other classes as well. Why would someone want a Class D?
1. More watts per dollar (usually)
2. If you keep it powered 24/7 then it's always warmed up. Even for a few minute listening session where you probably wouldn't turn on an A or A/B amp for just a few minutes.
3. No heat if your room gets hot.
