If you are seriously considering Class D amplifiers, you might want to send an email to Audiogon member "Plato". He's a reviewer, and he has heard and reviewed the PS Audio amp along with at least one or two other Class D amplifiers. He can give you a well researched opinion based upon listening.
BTW, I have auditioned the NuForce Reference 8, Channel Islands D100 and D200, McCormack DNA-2 Platinum Revision and Odyssey Audio Stratos Extreme Monoblocks in my system with a tubed preamp (First Sound Presence Deluxe II and Modwright SWL 9.0SE). Several of them are excellent choices. They all have strengths and weaknesses.
