I have no experience whatsoever with the VP180, but will say that I experienced a substantial positive chance when I went up from a VP150 to a VP160 in my system (M60 mains).

Oftentimes, the decision between a 180 or a 160 might come down to how much room you have. I have room for the 180 in my setup, but am 100% glad I made the choice with the 160.
