I highly recommend the Outlaw 990 pre/pro. I have paired that with the Outlaw 7500 amp and the sound from my M80's is outstanding. Definitely a bit more than the Denon, but it comes with plenty of horsepower! 990/7500 combo is currently 2,348 (5 X 200 watts) and the 990/7700 is 2,798 (7 X 200 watts).
