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.

I own & really enjoy the best/ worst of both worlds. Full class A, 100 watts / side tube integrated amp. Rogers High Fidelity EFH 200 Mark II. Sounds great; very powerful, dynamic, detailed w/ full frequency extensions but as airy, beautifully toned as I could ever want. It should at its price & does & should do so for a long time. 
 

That said, it puts out some serious heat all the time. Living in New England, I don’t mind 8 or 9 months of the year. For myself, very much worth the trade offs.

I have a Pass Labs class A amp and yes it does get warm but never felt any heat issues from the amp. I live in the northwest where summers can get hot here and we don’t have AC. Still not a problem. I went from a class A/B tube amp to this amp and am very pleased with the upgrade.

So even an audio forum can’t get away from political comments. 

They’re in my some of my active speakers - and they’re excellent, especially in winter.

Living in Florida it's a double hit to the electricity bill. First the cost of running it, then the cost of running the AC to cool the room. I'll keep my Benchmark AHB2.
