I know there are others using an Onkyo receiver with the M80s with no problems. It wouldn't have been my first choice with the M80s but don't hesitate to at least try the 605 with them. It very well might work if you don't drive it to hard. The worst that will happen is the 605 will go into protect mode, give it a try.

Did you read the link from Audioholics where they used the 601 with the M80s?
