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

Almost all push/pull class A amps are really very rich class A bias AB amps. For example the Pass 30 watt class A amps are 30 watts class A but they are reall75 watt AB amps. Look at the Stereophile tests. And things get worse as load impedance drops. About the only amps you can be sure are always class A are single ended amps which are class A due to topology and are almost always low power anyway. Then again these amps still run hot.

Perhaps the only push/pull amp that may really be called class A was the old Levison ML2 mono blocks. They were 25 watts/8 ohms, 50 watts/4 ohms and 100 watts/2 ohms and class A all the way down to 2 ohms.

While I'm all for Climate Change and have the Asthma lungs to prove that it's (I grew up in a Steeltown). My setup is kind of an Oxymoron (?). BATVK50-SE with 8 6H30 tubes and she gets very hot not long after it's turned on. The BA Preamp feeds a pair of Orchard Audio Ultra Amplifier modules which in turn are powered by a 1500VAC, 20A Torroidal.

Sounds amazing so yeah. Tubes feeding solid state is the way to go I guess.

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
