I've been looking for a "monster" center for some time now & the VP180 sure fits the bill big time! From what I can gather the VP180 should mate well with neutral/warm speakers of another brand. My Polk LSi15's are (to my ears) a neutral/warm sounding speaker so I'm going to give the VP180 an honest audition in my system. If it works out maybe the M80 v3 towers just might be a future purchase. And lets not forget the QS8 v3's as a new surround pair to replace my Polk LSi/FX surrounds. One step at a time though to get started. Any thoughts on the VP180 blending with the Polk's?
