Seeking hot running amps

plinius they run at 165 degrees they are biased at pure class a. plus they sound incredible

Ah yes, heat. Class A operation is the reason for heat. Fact is, if you want it to sound right, it has to be class A.

I've never understood why a person would spend thousands or 10s of thousands on a stereo and then compromise the whole thing (and the investment) because they were worried about heat.

A customer of ours in Guatemala runs one of our big amps and has no air conditioning. Instead, he has ductwork positioned in the corners of the room where the amps are, and has a fan at the other end of the ductwork, drawing the air out of the house. His room stays comfortable year round even if the amps are on all day (I know I was there), yet the room is quiet. Elegant solution.

Well, there is more than just "HEAT" when there is heat, there are tradeoffs, for every degree something runs hot, there is a reduction in reliability, as well, the heat comes from somewhere, it's energy, wasted energy, you wouldn't run your car full throttle all the time an use the brake to go 30 miles an hour, there are intelligent ways to use energy

Joule Electra OTL tube-based amps. I have a pair of their 100 watt versions in my dedicated Canadian basement listening room. I close off the heating ducts to the room and turn on the amps an hour before I listen. Works great for me - I STILL have to have a blanket on when I listen to music in the winter.

My vote goes to the Mccormack DNA-1. The fact that it operated so hot, actually contributed to my getting rid of it. An excellent sounding amp.

Thanks
