Current system: B&W 603 S2 front, LCR6 S2 centre, 602 S2 rears. SONY STRb 930 Receiver The room is 29' x 15', vaulted celing, hence going big with the original set up. However, it now sounds quite 'boomy', and I'm looking at 2 steps upgrade (in line what my relationship will bear). Main use is DVD, arthouse movies, though I am partial to the occasional Star Wars /Matrix etc. Stage 1 reshuffle, now (circa £1000). One piece of advice to improve the current setup at low cost has been to sell the 603's, move 602's to front, add subwoofer (B&W 675?), and add 601's (or 602's) as rears. And possibly spend £400-500 on a new amp receiver. Stage 2 upgrade, by end of year (£3000+?). Looking for a real improvement whilst maintaining the aforementioned relationship. 7 channel a must, liked the B&W CDM range when I purchased the existing setup. 1 Any B&W owners with comments on the stage 1 from B&W owners? 2 Any advice on recommended speakers or amp that would suit the room and typical use. Not commited to B&W and would consider new or used. 3 Any suggestions on staging upgrades, e.g. would spending on a £750-1000 amp with existing speakers now make the biggest difference? Or subwoofer that could be part of the future system? Thanks!
