I just want to offer another round of thanks to everyone that's contributed to this thread. Lots of really great advice here, and I appreciate all of it.
What you say, spiff, about a crummy sub making your music sound like poop, I think that's absolutely correct in my situation. My current sub shakes, rattles, and rolls the china out of the cabinet, but it can't replicate the fine detail of Yo Yo Ma's bow over his cello - and that's what I'm missing.
My mind is pretty much made up as to upgrading the sub first. Yes, my opinion has changed. It's becomming clear to me that the sub is currently the 'black sheep' in the herd. Whether I upgrade to M80's, B&W's, or some other brand, it doesn't matter. That ancient, boomy sub neds to be replaced with some fine offering from Axiom, SVS, or HSU. Why replace perfectly good m22's when it's the sub that's the crummy component? Right?
Perhaps it's time to just face the music and order an EP500.
