whats the budget and what center size are you looking out for? Surely you don't want something too big to spoil the looks and ambience....you can get a lot of center speakers which are decent in size and awesome in performance....
Why not see the JBL and Polk (RTi series) line up? Which city are you based in?
Hi
What % is TV vs CD usage for you- preference should depend on :
1.Center is more effective for TV (many brands listen to few JBL, Bose.)
2.For Music a very good Sub woofer like SVS will be more effective.
