Br3098, I appreciate the humor but seriously, the heat of our amps is quite manageable. Up here in Minnesota we see the highest dewpoints recorded anywhere worldwide and our amps are easy to live with even in the summer. However the heat comes from being class A, not the number of tubes. You can run the amp in Standby all day and at the end of the day, put your hand on the tubes without fear of burns. But from stone cold, within a minute the tubes are way too hot to touch because they are conducting.
IOW a solid state amp of the same power that is also class A will heat up your room in much the same way- it will make about 85% of the same heat. The real issue is, what do you want the system to sound like? Real music? If so, you are going to have to go class A- all other classes of operation are performance compromises.
Now it may be that you can find nice-sounding amps that are not class A, in fact they abound. But the very best, the ones that stand apart- they will be class A.
