Congrats on the new speakers.

Mojo made an interesting point about preferring simulated surround to stereo after upgrading the center channel. I tried the same "surround vs stereo" comparison when I had VP100 center and concluded that I liked stereo better, but maybe it's worth re-doing those tests now I have the VP180.
