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

@erik_squires I did not find the sound coming out of that M-10 as good! That was the unit I sold. 

I love my Pass class A amps.  Yeah they're hot, but the sound is magic to my ears.

I used to keep them on all the time.  Nowadays, I turn them on about an hour before listening sessions, saves on my electric bill and heat generation.

@jwei +1 that’s pretty much the routine. I also keep my basement at 63 degrees so I don’t heat it in the winter unnecessarily and whatever the heat generated by the Pass XA30.8 amp doesn’t bring the temperature up that much. 
In the summer the basement is cool so it’s rarely a problem.

I have the Pass XA60.8 mono blocks on my list of amps to try.  

24 hrs for my monos to be their best sounding. 
 

such a difference from initial power up to same time next day listening.

do not get those batteries wet in your car

Its inadvisable to submerge any car, gas or electric.

I have a fried with solar in his home and he is still battling noisy power in his system when on battery power

Your friend obviously has site/product quality/design specific issues. My system isn't designed to take us off the grid in the event of nuclear war, ours is designed to supply the grid with a similar (in our case a little excess) amount of generated power that we consume. We spec'd our system to eventually supply three electric cars as well as potential max usage for a 4,000+ sq ft home.
