I've always heard one on the no no's of HT is not having your center match you fronts.
I'm running my 80's with an Aperion 533vac center, while it sounds okay to me, not being a real expert what am I missing in terms of sound and quality.
Also with my mains only about 6 feet apart would I benefit by switching to the VP150?

A computer once beat me at chess, but it was no match for me at kick boxing.
