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

Amps that sound great will always have a following, whether they run hot or are ridiculously inefficient.   
 

I like tubes but if I didn’t own tubes I would definitely look at a low powered Class A amp.   
 

Years ago I borrowed a Pass Aleph.   It ran so hot the heat sinks took on a blueish purple color over the years.  It was ugly and ran hot as hell but it sounded great. 

Myself not a fan of the space heaters. Regardless of how great they sound. Keep in mind what the heat means: wasted electricity / inefficient designs. I do now recently own 2 carver tube amps but they don't kick out much heat. Some but not bad. Primaluna tube pre has minimal heat. 

Come summer though I'll buy another Class D something as it's hot AF where I live. 

With the newer GaN and Purify amps and with future improvements surely coming down the road I’d have to think long and hard about buying a traditional SS Class A amp.  But at least some Class A amps from Plinius and Clayton have a hi/low bias switch so when not listening critically you don’t have to heat the house or assault the electric bill.  Nice to have viable alternatives.
