...I thought we only needed as little as a half a watt for the M80s at decent dbs



That's right. In my 4,000 cubic foot space, half-a-watt per M80 gives me an average SPL of 75dB. With the 600 on, the average goes up to 85dB. This is my typical listening level for music. For movies, I got up to a few watts on the M80s.

Last night, while everyone was sleeping, I was down to less than a tenth of a watt per M80.

What would happen if the Onkyo is set to 6 or 8 Ohms? Do you have the M80s set to small and are you crossing them over at 80Hz?
