I just went from a VP100 on top of the screen with a VP150 below the screen to just the single 150 below the screen and it sounds better in this configuration, I'm thinking there's some noise cancellation going on with the two centers ... but of course six months ago the 100/150 combo sounded perfectly fine. I believe *not* focusing on exactly where the sound is coming from and positioning the center ideally makes a big difference.
