I would give the Rotel amp and CDP a chance to break in as well. I had a Rotel 1052 reciever and 1072 CDP and they really benefit from breakin as well. Also look at moving the speakers around, check relationship to walls etc as room acoustics will also affect the speakers.
Tips for warming up Rotel + B&W system?
I recently purchased Rotel Integrated amp and B&W 703's to pair with my broken-in Rotel 1072 DC player. I've only had the system for 2 weeks, but I can't notice any improvent, The broken-in system sounded very good in the store but at home it sounds cold, dry, sterile, with harsh highs. I find the more I listen, the less I want to listen, which only slows doen the breaking-in process. Are there any audiogoners who've had experience with taming overly trebly B&W's?
