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.

For 2-ch system, I use NcoreMP, 6 channels (LXmini + subs) use 0.8 A (120VAC = 96W) including power to N130 - everything runs cold.

For HT system, the Denon X6400H (class A/B) runs so hot, I added a cooling fan, which is very noisy when it turns on, and is distracting while watching movies.

Having that experience, I avoid gear that needs cooling and/or is very inefficient for myself. I also wouldn't let heat prevent me from chosing gear that is worth the compromise - if I thought it was worth it.
