I bought my Axioms back in september, I've been happy with their sound quality except for the VP150. I've noticed that it lacks a certain theatrical quality. No matter what I've tried it can't really stand with the M60's. I've tried raising the volume on the reciever and sitting closer to the screen but I haven't noticed an improvement.
I noticed on the specs that the VP150 has high wattage output. I believe something like 400W. Would the VP150 sound better if I were to get another amp to power it? I know Audioholics even recommended dual 150's. What are your thoughts on this? Would dual center channels remedy my problem? Or simply more power? Or even a higher end center channel from another company? I would gladly spend the extra money if dual center channels would provide a significant upgrade, considering I primarily watch movies.

my setup: Vp150, 2 M60's, 2 QS8's, 2 M2's -- Yamaha V2600
