When I spoke with Brent (who is running 2 vp150s, 1 above and 1 below his screen) back in May about whether I should try to combine the vp150 with the vp180, he stated, "No the 180 would just blow the 150 away."

He also suggested that the vp180 would most likely stand on its own and not require support from an additional center.

It sounds like your listening impressions are consistent with Brent's assessment, thanks for sharing.
