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

Having said that, I look forward to consulting with the dude who makes March Audio amps. 

Class D technology is something to think about for anyone seeking nirvana, should one understand how appropriate components have to be matched.

Otherwise, not.

Had spectral ss gear for over 20 years.  Class ab and the heat fins ran hit but not to a high level and left them on continuously.  Fell in love with a class a esoteric during a demo, and tried the more efficient models in the line up and chose the class a.  300 watts at idle so it is on only during listening and most times an hour or so.  I’m in Tampa so the heat is an issue, turn down the ac a degree.   My pool pump is 900 watts and runs 10 hours a day, so the amp has little contribution to lower needs.  

I'm not so worried about the heat. Where i live it helps keep the house cozy 6 to 9 months out of the year.  On the other hand, in Massachusetts their crazy "Strategic Electrification" program will mean my next electric bill will show an electric rate in excess of $0.40 per k/W.  So my admitted inefficient, but great sounding system will easily be adding $100.00 per month.  Yes, as class D evolves and improves it will be a consideration.  Yes, i am concerned about the value of my BAT amps and Tube preamps and my fan cooled A/B amps in an already shrinking audiophile market.      

Shrinking audiophile market jimrobie? I think you’ll find the opposite if you talk to dealers here in the US. Tube gear sales has increased considerably and I’m pretty sure audiophiles aren’t worried too much about energy efficient systems. I buy energy efficient cars, refrigerators, dish washers, light bulbs but am not too concerned with my music system. I will listen in the dark if I have to. It’s too good!

I loved my Chinese Class A amp. It sounded better than the un-rebranded Sophia A/B I have now. (B.T.W. - Sophia's profit margin on these Chinese-made amps is huge!
