Awwwww.....crap! I was quite intent on keeping my V2 and V3 stuff.

So how do the V4 500's compare to the V2's, performance wise? I have two EP500's in my room. What would a reasonable expectation be if I were to upgrade to the V4's, with respect to sound quality? My room is 12X18X9. M60s and a VP160 with three sets of QS-8's.
