I have owned both the VP100 & the VP150 and found them both to be very good centers. I'm not running either one of them now only because I needed to match my fronts but they are both very good center channels none the less.
Are they the best I have heard? probably not. That honor goes to the top of the line Paradigm. For me at least it was as close to being the perfect center channel I guy would want.
However with that being said, the difference between the Paradigm, Axiom or even the Monitor Audio I have now are subtle to say the least. I'm of the school that says your fronts should match. If you have Axiom for your mains, get an Axiom center channel.
