Matthew Hill has the Epic 80 system (the same one you are getting) and actually drove it with a 1050 for a while before upgrading to a separate amp. He posted some comments here (near the bottom). I would have no qualms using the 755 to drive the Epic 80 system -- the 4 ohm load for the M80's will not be a problem.
