I just took my integrated Setton amplifier out and replaced it with a Primaluna pre and two Emotiva monoblock amps. I wanted to compare the sound anyway. The room temp went up 1 degree. It's not a big room. But hey, in southern New England every little bit helps, right? Wait, the outside temps are in the twenties now and not the single digits. Hmmm. I may have to rethink prolonging this test...
