Ok I just got a 3802 a week and a half ago. Now I assume that reference level is when the volume indicator is at 0 (the 3802 goes from -70 to +18). Is that right? Because if it is then I can't imagine listening to anything that loud for an extended period of time in my house. I usually hover between -24 and -10. Second question, I have Axiom m60ti's for mains. At what point is there too much power going through the speakers. I doubt my 3802 will tax the speakers that much but what if I added an amp for some extra power? At what point is my power source too much for my speakers and how do I tell when I get to this point?
