Power amplifier running too hot?

[Craig B]

I decided I didn't like hot running amps. I had an Emotiva XPA-1 and XPA-2 per side. XPA-1s, when switched into "Class A" (just much higher bias setting, so enriched A/B) got VERY warm.

When I decided I didn't need two mono amps per side, I sold XPA-1s and kept the 2s.

How do you feel about your home heating system?

How do you feel about your home heating system?

Indispensable in the winter...but trying not to heat the house in the summer.

And my main heating system is heat pump based, so quite efficient. Resistance heating...not so much.
