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 enjoy warm and full sound out of class A solid or SET tube amp.


Thus I am happy to live in Pacific Northwest Washington State.


It is not that hot during summer.


It is good to have extra heater during winter.😀


Also the cost of electricity is the most affordable in WA.


Thus I may live in Washington State for my life.



I have to say that over the period I have running my Class A mono amps, coupled with my tubed preamp, I have been loving my music again. There is a sweet spot with these mono Class A amps that allows listening with no fatigue, glare or otherwise unwelcome issues or noise. I would characterize them as "warm" sounding so it depends on what you prefer.  My units have a stanby mode so the "Heat" is only an issue when in use, but they do run Hot! I have also installed some micro fans which are very silent to move air from behind the units which helps.

Overall the most musical combination I have owned and enjoyed!

I have no intention of getting rid of the two class A stereo amps I use in my triamplified DIY fully horn loaded system because of the anthropogenic global warming scam.

I have a class A amp on my main system and a EL34 tube integrated on a second.  The heat is a non-issue for me. I've owned some good quality class D amps (2 different Bel Cantos and a VTV Hypex along with some more basic units) and like the sound quality of my current amps better. The only advantage I find for class D is that they can be left on all the time, but I really don't expend that much energy in pushing the on/off switch.
