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.

Hello gammonit_2000,

Agreed, as long as you buy a model that still carries a 20 year warranty.  I believe Bryston reduced the length on some of their models.

I know the digital stuff is 5 years but AFAIK the amps and preamps are still 20 years.  I could be wrong, it has happened before.
gammonit_2000,

      Looks like you're correct except for  a few detals, below is from Bryston's website:

It's interesting how this 7BSST2 combo with the BP26 and MPS-2 improved the sound over my old 4BSST with a BP20 and MPS-1. 

I suspect OP will fall in love with the PS Audio and live forever happily in Class D.  Or not.  Really seems a step back, all these rave reviews such as the glaringly bad KEF LS 50 get old.  I don't even trust the rave reviews on the Bryston BCD-3.  I am suspicious.  Really though their software apparently sucks on the digital side, like bad.  Mickey Mouse or was if Manic Mouse?  And a $375 remote?  I have one, and it's odd.  BR2
gammonit_2000,

     Have you ever tried a good quality class D amp in your system or heard one in any system?
