Seconding the Atma Class D's. Tube amps and A/B amps just roasted me in my hot and small upstairs bedroom. Atma's solved that issue with zero heat and they don't even get warm. I don't think I'll ever be selling them.
Amps that don’t impersonate space heaters.
There have been some epically hot periods in metropolitan Chicago this summer. I have had a long running affair with a pair of Avantgarde Uno s2’s and don’t really require a great deal of power. I have two dissimilar but equally compelling amps (a Pass 30.5 and a BAT vk-56) both prodigeous producers of heat creating a sauna like environment in my library/listening room the HVAC system not withstanding. What, if anything, have you boys and girls found that might replicate the qualities of my beloved amps minus the potential for 3rd degree burns and heat prostration?
Cheers and good fortune to you all.
