Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???

I installed new 500w p/s modules in my NuForce, then sent them to Bob Smith @TDSS for the rest of the goods, amp searching is over.

Tube Dac and Preamp in front of these, mandatory in my book and ears.

Other amps I’d ever consider would be NuPrime Evo-1 or Rowlands.

As far as warm up is concerned, I cannot hear any differences in a cold start up vs. the amp having been on for 4 hours... other than Bourbon has taken over and everything in the room is just better.

+1 and more!!
 
Amps are adjusted and calibrated at the factory for peak performance after a short 1/2-1hr warm when they've reached operating temperature, even tubes, to say they sound better after hours and hours is a furphy.

Yes electrolytic capacitors like to be formed/polarized with a little time from new, this again is only a short time, and not every time it's turned on.

Me neither. I can only hear it after at least 24 hours.  I suspect this is very amp specific however. But mine are stock ICEpower modules. YMMV.
