Without going into the advertising jargon of Bob Carver, the way it is done is with a very efficient power supply. Much better than 50%, which would be typical of a class A amp. Bob calls it a downtracking power supply. My understanding of it is that it tracks the input signal and swings/adjustes the amplifier bias voltage to track the input signal. So it puts out a lot of power but has a much smaller bias voltage delta to be wasted as heat. It stays pretty cool all the time. But, as I mentioned, I have decided to buy the McIntosh MC402 to replace it. Not that I don't like the Sunfire, but because I have always wanted a McIntosh and this is my chance.
