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

Clio and Ralph:

Thanks for the feedback.

The D amps are pretty old (maybe 20 years).

I may try adding an 8 ohm wire-wound to the Sharp as It's set up now @ the computer.

I haven't seen the Sonic Impact's for years - not certain if I kept them.

I'm down to one Sharp system now (2 died and I gave 2 away).

Class D is good for the spare bed/computer room as it has a large wall to wall window and no air conditioning.

@dekay Uh, Yikes! A lot has happened in the class D world since 20 years ago!! I couldn't take them seriously back then.

@tweak1 there are 4 of them on USAM right now. All priced down and dirty.

you forgot about the Krell KRS200. Pure Fixed Class A down to a 1/2 ohms. One of the most powerful Pure Fixed Class A Amps on the planet.

i agree with you 100%
 

My response as well:

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
 

Also Boulder makes an incredible Bias Class A amplifiers for quite some time and they don’t heat up your room. I know they are expensive and not everyone can afford it but if you constantly complaining or competing with Class A vs Class D, this should quite your noise/ maybe not. 

I like the sound of Class A and also Magnepan speakers. So a dilemma. My solution is low-power Pass diy amps with high-sensitivity speakers for casual listening around the house, and a Class D amp with tube front end driving the Maggies in my listening room. I don’t think I’ll ever own a Class A amp over about 25 watts. The electricity consumption does bother me. It’s wasteful. But then, I’m also a gardener with a house on more than an acre, and I use a lot of water. We all have our priorities.
