I love PSB, I think they are one on the best loudspeakers on the market. I am currently running Image 6t's for my tower speakers. I really like them. But I am also interested in upgrading my center channel speaker to the C-6i. I want to keep my front soundstage as uniform as possible, so with doing that I am also looking at the Silver I's for the mains. I have heard really good things abouth the C-6i and the Silver I's. I am just wondering if there is that much of a difference to justify the extra price for the Silvers. Or should I just keep my 6 t's and get the C9 center channel to match the 6t's? Any help?
