bug: I really do not believe that many forum members/ users fully understand the concepts of duty cycle, power supplies, listening levels, and how they interact with one another. I do believe that the manufacturers take big advantage of this lack of knowledge. Of course, the specifics can be quite complex and technical.
Yes, I believe that it would be "best" to have separate circuits for your amplifiers. No doubt about "best."
But, then, again, what is OK or what will work??
I think that is the question that you are asking!!!
If I get one of those 790 amplifiers, I'm going to try plugging it into the same 20 amp circuit that I have the rest of the gear powered from. If it works, it works! If it doesn't, I have plan "B." The breaker box is in the back of my HT room and I have an attic opening to the crawlspace in the ceiling. Shouldn't be too difficult to add another 20 amp circuit.
