You might see if you can find a Marantz MM9000 online somewhere. I have one and I love it. I have M60's, but I have no doubts that the unit could power M80's. It is rated at 170 watts x 5 channels at 8 ohms. You could use your receiver to power the other 1 or 2 channels in your system (as I do). I found mine for under $700
