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

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. 

I tried and ended up moving the GaN and a Purfi amp to a secondary system and one to my daughter's condo. Just not for me, maybe one day. 

I actually have a Heed Elixir in my office that runs cooler than the NAD-M10 I had in my office. Must be the Transcap technology these Hungarians are using in their Class A amplification. 

NAD's hybrid tech is one of the most innovative amp techs I've seen in recent years.  It runs hotter than Class becayse it has a small Class A in between the Class D.  Very cool stuff and it sounds pretty good too.
