Mark,
I believe that if the power of "what-if-itis" could be harnessed, we would no longer be dependent on fossil fuel. With that in mind, I will not try to dissuade you from chasing the VP150. I will tell you that my VP100, in a 16x22x10 room and flanked by M60s is well beyond just adequate.
BTW, I have not heard a VP150 (it would not fit in my setup anyway). I regard this a good thing since I am pretty much the "Typhoid Mary" carrier of the what-if virus. My view towards this type of thing is that, especially at my age, it's pretty late in the game and I don't want to be "almost happy" with this stuff.
Can you catch an audition through Amie to listen the speakers you are considering? Whatever you do - be sure you enjoy the end result
