HomeDad, With regards to the onboard amps of the Denon 4806, the rating of 140 wpc is at 8 ohm. Have you been able to find any information as to what the output is at 4 ohm for the M80's? If you run the Denon on "Pure Direct" where all auxillary circuits are shut down in order to direct more power to the two front channels, what is the calculated/estimated output at that point? I have not been able to find information on this as of yet, but I would think it could be approaching 200 wpc.
