I know there are some on here that listen to classical with M60s and love them. The EP350 is a good deal but there will be those that mention going for an HSU or similar sub from else where, which plays lower for the same price. As for the VP150 or 100, take your pick they both are great centers. I have the VP100 with M22's and it matches perfectly as does the 150 by all accounts. If there is a space issue then go with the 100 otherwise the VP150 to eliminate any what if questions.
