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.

No heat concerns here. My pair of 1980s Crown PS/200 amps benefit from a really good chassis design that keeps them very cool without a need for any fans. Actually cold when playing music not even close to being hot at idle.

I don't have air conditioning.  I had to abandon (at least in the summer time) my 400W class a amp for a 180W class A amp.  (I'm talking watts of heat, nothing to di with watts per channel which is close to single digits).

@retrocrownfan Your ps200 amps are not Class A, they run squarely in class AB or B.

Pass XA25 owner.  I am inconsistent concerning leaving it on or off.  Last month my energy bill was for 300KWh.  The amp gets to 120F at most.  I like it, I won't get rid of it.

I love the sound of a big ass, power sucking, space heater, street light dimming Class A amps…Glorious!
