The Onkyo receivers only give you a choice of 4 or 6 ohms, Ken is right leave it in the 6 ohm setting and you should be good to go with the M80s.

There are others here that run the higher end Onkyo's with the M80s with no ill effects.

Onkyo HAS to give you that advice to cover their own ass IF something were to go wrong.
