>>Sorry, I needed to add that our room is 15x15x8 with the listening position about 10' back. We use this mostly for HT and some music. Thanks.
The pattern I saw was that people in normal sized rooms didn't hear any significant difference between VP100 and 150, while people in large rooms did find the 150 sounded better. Based on your room size I wouldn't expect you to hear much difference. Is there anything else you wanted to upgrade that might be a better use of the $$$ ?
The other rule of thumb is that your center speaker should not be wider than your television or it looks funny
