Ditching Class A Amps due to Heat - Sort of a Poll

I own a Luxman 590AXII class A and would have a hard time going back to Class D, although I have owned Class D and G before and I liked them very much. I'd go with Tubes, but don't want the hassle and then I'd get into tube rolling and that expense. I don't mind the heat at all. Odd to me that it's a big issue. 

And yeah, cut out the stupid political comments, go over to Twitter if you want that BS. 

hmm... I dunno, I'm no "class" expert, but the Marantz Ruby is some type of class D and sure sounds nice to me and to the various critics I've read.  The Technics SU-R 1000 is None Of The Above, and it is supposedly hella great.

I'm not married to any "class"... there is no one class that universally sounds great or bad.  It's all in the execution.  

another possible compromise if you gotta have at least some "class A" in your life is the Arcam amps... A first x watts, then switch over to B (?) after that.

I like that heat source. It was 10° here a few days ago

Have you done away with your Class A Amp due to Heat concerns?    NO

Will you be moving away from Class A Amp due to Heat concerns?  NO

Will you never buy a Class A Amp due to Heat concerns?  NO

Since the early 1990s I have run Krell KRS200s uprated by Krell to 400W per side.  They are probably about the hottest amps around and can pull down nearly 2kW per side.  Sound is wonderful of course.  It's a big room and in the basement so it doesn't get too hot.  I don't heat it in the winter as it's dedicated just to music.

As for the global warming lobby, it can go swing a cat.  In the recent COP-OUT 22 all the big countries of the world were unable to agree any positive action.  We are all too greedy and competitive.  They never agree any ACTION, they just make promises they do nothing to keep.  1.5C is already gone, measurements show we've already reached it.  Don't worry, humanity will adapt, it always has done.  Sure some will be inconvenienced, some will die.  It's always been that way.  Anyone wanting action on global warming needs to pray for a meteor hit.

To your question - yes, I moved from Class A amps (MSB) to Class A/B with Pilium and very happy with the change. Pilium amps run cold and sonically they are superior as to my taste. It is a kind of a rare occasion when you can enhance pleasure in an environmentally friendly manner.
