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.

Wots damatta? Is everyone around here overliteral?

Personally, I abhor wasting energy. Everybody else can "waste" whatever they want to.

@erik_squires I did not find the sound coming out of that M-10 as good! That was the unit I sold.

I love my Pass class A amps.  Yeah they're hot, but the sound is magic to my ears.

I used to keep them on all the time.  Nowadays, I turn them on about an hour before listening sessions, saves on my electric bill and heat generation.

@jwei +1 that’s pretty much the routine. I also keep my basement at 63 degrees so I don’t heat it in the winter unnecessarily and whatever the heat generated by the Pass XA30.8 amp doesn’t bring the temperature up that much. 
In the summer the basement is cool so it’s rarely a problem.

I have the Pass XA60.8 mono blocks on my list of amps to try.

24 hrs for my monos to be their best sounding. 
 

such a difference from initial power up to same time next day listening.
