I am trying to decide between the following music/5.1 HT setup. Front: B&W 603 S2 or 602 S2 Center: CC6 S2 or LCR6 S2 Surround: B&W 601 S2 or DM303 The price difference between the 603 and 602 is larger than i thought. Is the difference worth it? If I go with the LCR6 center, I'll need to downgrade the surrounds to the DM303. Bottom line, should I spend more on center or surround? Has anybody compared the CC6 and LCR6? 601 vs. 303? Thanks.
