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

I have class A mono’s and never give the heat output a second or even a first thought. It is what it is and who cares. It is nice for everyone to have option to buy what they like.

There may be two ways to think about this… you love your speakers so stick with the amp that brings out their best… or….

You are committed to class d so you find the speakers that brings out their best.

Either way you are trying to optimize the amp, speaker, room combination to deliver the sound you are searching for. I suspect that most of us are going to try many combinations… and keep trying them because that is part of the fun.

I have 2 systems in my house, both Sugden ClassA . Will never own anything but. The upper system are the Sugden MPA-4 mono blocks, and the basement is the IA-4 integrated amp. Both systems have the amps on top so they can dissipate the heat. With a fluke meter and amp clamp, each mono block pulls 3 amps of power when turned on.  Rated output is 165 WPC Pure class A Bliss.

In the winter Class A is great.  Like one guy said, the total volume, Pun intended, does not add up to much. A flight across the state in a jet, or buying an Amp from "Jyna" is more of a sin.  Be "Amurcian" be Class A. Buy a Coda 11.5 Class A .   If you want, if not, there are many great sounding cool Amps, Pun intended, amps.  

My 4 Class A monoblocks use about 1/2 kW total, which heats the room nicely for most of the year, for less than a dollar a day. Not ideally green, perhaps, but then I don't drive a pickup truck or commute 30 miles either.
