After 4 years I'm finally getting around to putting together another Home Theater. I've decided on B&W mains, center and surrounds, a SVS sub, and either a Rotel or Denon reciever. The problem I'm having right now is deciding which combination I should go with. Combo A: DM604 mains, LCR600 center, and DM602 surrounds. Combo B: DM602 mains and surrounds, and LCR600 center. Combo C: CM2 mains and surrounds, LCR600 center. I've done quite a bit of listening to the 604 and 603's, but have not yet heard the 602's or CM2's. I plan on auditioning these last two very soon. So, here are my questions. 1. Are the CM2's worth a little extra money over the 602's? 2. Would going with the 604's over the smaller 2's really have any benefit since everthing will be mated with a SVS sub? 3. My first round with the 4's and 3's was with the Denon 2805 which was a blissful combination. Is there a noticeable difference between Denon and Rotel? Although I didn't get a chance to hear the Rotel, the salesman thought the extra bucks for the jump from the 3805 to the Rotel was worth it. 4. Which sub would mate with the B&W's better the 16-46 or 20-39? I apologize for all the questions and I realize that I need to do a lot more listening in store, but I'd really like some opinions from those who have similar setups.
