I made that jump and to me it was worth it. I find the extra mid-bass the M80's provide over the M22/sub enhances my HT experience and music listening. I wouldn't move to the M60s, as I found they do not add that much extra midbass over the M22/sub combo, at least not enough for the price difference between them, IMO. Don't get me wrong the M60s do add more to the equation than just the M22/sub but not quite enough to warrant the cost of upgrading.
