I currently have abit of a mix of speaker in my home cinema set up. Mission 773e's front pair, MS T1000 centre, kef coda 8's rear, Rel Q100e sub. Will replacing them with the B&W VM1/AS1 be an improvement? The missions are a very good speaker but are the B&W's as good to replace them or is it a downgrade? I only have a smallish sitting room and mounting the B&W's on the wall would free some space up for me. Reciever is a Sony strdb 930, but looking to upgrade this year to either a Denon AVR 3803 or Pioneer VSX-D2011.
