Alan, In that case, Continuous Power output (DIN) is rated at 135 watts at 6 ohms. Maximum Power output 160 watts at 6 ohms. No 4 ohm ratings other then what I mentioned before. I will go with M80's and if the Onkyo has an effort problem with them will get a Denon 3805 or since I really like the Onkyo maybe a Onkyo 901.
And, thanks for all the help with this
