My 4 Class A monoblocks use about 1/2 kW total, which heats the room nicely for most of the year, for less than a dollar a day. Not ideally green, perhaps, but then I don't drive a pickup truck or commute 30 miles either.
Ditching Class A Amps due to Heat - Sort of a Poll
A discussion elsewhere about the future of Class A made me wonder how true one statement really is. So the questions are...
Have you done away with your Class A Amp due to Heat concerns?
Will you be moving away from Class A Amp due to Heat concerns?
Will you never buy a Class A Amp due to Heat concerns?
I only have a class A/B unit that does Class A up to 6 watts with almost no heat so really can't speak for those who have used in the past or currently own and run Class A Amps.
