Yes, the M80s are no slouch. As I have a pair as well as the 1100s. Good choice!
The M80s to me seemed that I wanted them louder and louder, they can play so clean. The LFRs sound to me just what I want to hear. I actually can't hear where the sound is coming from on a good CD with the QSs and the DSP box with the VP160.
I do have Outlaw mono's running the front soundstage, but am saving for an Axiom 1500 5 channel amp. Then that's it....
