The CDM's use B&W's metal tweeter and is their lowest grade tweeter retailing for about $100 each. The next step up is their aluminum tweeter and it sounds much better than the metal one.
Given you McIntosh amp and BAT and if you like the B&W sound but the tweeters are too bright, I would suggest their 803S speakers. With the right speaker cable (i.e. Audioquest CV-8) they will sound great. The CV-8 dbs is slightly on the warm side and will tame the brightness of the B&W's even more without loosing any detail.
Of couse their diamond series tweeters are fantastic, imo, but that is out of your price range (ie 803D).
