Get a new 2-channel amp, ditch everything (no sub) and get M100's. I just upgraded M60's to the 100's. I got a 500 when I got the 60's 4+ years ago. The M100's don't need the sub for music, not for me, anyway. I know the M80's fairly well, as a member here is also a neighbor of mine. My 100's are the first speakers I have ever owned that finally make classical music sound like the entire orchestra actually showed up and EVERYONE played. The dynamic range is amazing and, at last, someone can flesh out all that stuff from the murky depths and bring it a clarity that I have never heard (read: could afford).
They are a stupid silly bargain from some really smart peeps.
You are THE listener the 100's and 1100's were made for----2 channel old-school people. You'd probably love the 1100's, but the whole set-up is a lot more money for them and their electronics. Another bargain, but in a different league.
Good luck with your choice(s)
