In reply to:
at this point, i'm leaning toward a 5.1 m80/vp150/qs8/ep600 (epic 80-600) system because i like big full sound but am still completely open to suggestions from those that know more than me.
Jallen, although I am in no way an audio 'expert' I can tell you that I have both a 60s system and an 80s system in my home and I wouldn't talk anybody out of buying a pair of 80s over a set of 60s if the difference in price were not an issue.
If someone were to rob my 60s at gunpoint I'd give in with a fight, if the 80s were the target, that SOB will be the sorriest soul on this planet for even the thought of trying to rob me!
And that's being honest.
