I have all the speakers you have except I opted for the VP150 from the start. I can't tell you the difference between the two, but I can tell you you'll likely be happy with the VP150. It matches well w/ the 60s and plays plenty loud. Very good for dialog and detail.

I just re-calibrated my system (somehow all the settings were erased) popped in "Nemo" and hit 101 db at -12 on my Denon 2802. Crystal clear, really mind blowing.

Have you tried calibrating with the VP100?
