Amp with a hard,clean and cold sound...

I owned a Bryston 4B SST and 14B SST, and both had harsh top ends in my system.

Frankly, I believe you are describing the sound of Channel Island D200 amps.

Grisslehamn, I think I understand what it is you're looking for. Give the H2O lineup a listen. They're amazing pieces of equipment. For comments and informaton go to the Discussion and Virtual systems sections of this website and look under H2O. There is a lot of valuable information and owner's comments there. Their website is www.iceh2oaudio.com

Interestingly, the CI Audio D200 and H2O amps are similar in their designs in that both utilize toroidal transformers rather than SMPS.

Tvad, you keep referring to toroidal vs. SMPS power supplies as if this was a significant point of some sort. Personally, I don't think it is.

I believe there are some very well designed power supplies of both kinds. I also have to say that I believe we have not seen the best from SMPS yet, and that designs like those from NuForce are starting to show that there may be advantages for SMPS such as transient speed capability and the ability to accurately and quickly track wide dynamic swings... You must consider that SMPS is in its relative infancy compared to conventional toroidal technology, and yet, some amps with SMPS are receiving very high praise in the audio press.
