What I meant is that you have watts rated at 8 ohms, other ratings at 6 ohms and still other ratings at 4 ohms. For the M80s, you are interested in the ratings at 4 ohms. I noticed in the writeups that your receiver is rated at 120 watts at 8 ohms. Does your manual have any other numbers at 6 and 4 ohms?
