Hi, I currently have KEF Q55.2's, Q95c, Q15's (rear) & REL Strata III. Amp is Yamaha 750se. Thinking of upgrading centre speaker...is the 200 overkill? Wan't to buy new so a 100c is not an option. Timbre match of 200 should be ok as it uses 4th gen soft dome tweeters like in my existing set up...or am I wrong? Advice please? Thanks.
