A lot, but so does everything else. There really is something to system matching. That said, I would have to ask what you feel you are missing that a new CDP would bring to the table.
Youve got some nice gear, however both the CJ and the B&Ws have a very unique house sound. I have found CJ preamps to be overly dark, and slow (IMHO based upon personal experience with the Premier 3 and the Premier 14). Ive also found the B&W to be a tab dark for my liking, unless properly matched (based upon poorly executed dealer demos).
FWIW, Id rather have a mediocre CDP with a great pre/amp/speaker combo, than the other way around (a great CDP with a mediocre pre/amp/speaker combo) any day.
