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.

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.

Hello benjosef1,

     If you're directing your comment to me, I don't think I ever stated you should not consider the PS Audio Gammonit-2000.  I actually wasn't even aware of this amp, which I assume is a new product.  I went to www.psaudio.com and didn't find any mention of this amp.  I also googled it and only saw references to this thread.  I really can't comment on products I'm not even aware of. 
      If you could post a link to any info on this amp, I'd be glad to learn more about it and offer my opinion.  I'm fairly knowledgeable about class D amps in general but this one is new to me.

Thanks, 
  Tim

"Some responses... one would think they are the President of the company they have such a strong desire to 'sell' a product to others.   I would just add a lot of the selling going on is fan boy praise. Folks just love something and will say and do anything to get others to join the club. So IMO a little standing back and taking a deep breath. Realize some folks are very persuasive, and you may not get the same love' for whatever they are 'selling'/praising to the skies. Just sayin'"

Hello Elizabeth,
