If you knew you were not going to make any upgrades to your system for some time (I know that's a funny statement but true) which would you buy? A pair of B&W CDM 9NT, or a pair of B&W 604s3 and a nice sub(possibly Paradigm PW 2200). System: Rotel 1095 amp/1066 preamp, 3 B&W LCR6s2, Paradigm PDR 12 sub. I live on the first floor of a house (cement under my carpet) and the PDR 12 just doesn't get it done for HT. If I knew I could upgrade my sub and center (to CDM series) sooner then later I would probably go for the 9NT's. But with engagement ($$) and then saving for a wedding ($$$$$$$) not to far away this will be my last upgrade for some time. What do you think?
