lordmelton: "Class A is the absolute best sound quality and contrary to popular belief they don't get that hot."
Sorry but you are wrong on both counts. There are plenty of AB and class D amps that sound just as good if not better, and "yes", class A does generate a lot of heat.
Axpert: I guess your comment "So, if the temperature of your room is more important that the quality of you audio reproduction, then perhaps you should go "CLASS D". (YUCK !! )" shows that you have not heard many class D amps. This is a pity and you should try to listen to more.
