same speakers and receiver here as well. Audessey set my sub to -10 db after I turned the gain down on the sub and recalibrated . I upped it to about -8.5 for movies, but it goes back down to -10 or -12 db for music.

The 3808 will have no problems driving your m80s.

Enjoy your new system!

The 3808 is becoming the popular denon receiver aroudn here it seems.
