Hi all, Looking to upgrade sub, with a budget of about £650. Upgrading system from KEF Q30/Q90c/Q10/Moel 30B to KHT9000 x 3 / KHT5001 x 2 / sub?? Thus far I have been considering KEF PSW3000 and REL STRATA 5. Also saw (but not heard) a B&W ASW675 for £650 today. Does anyone have any opinions on these and (more importantly) suggestions recommendations of anything alse I should consider? For esthetic reasons, maple/birch or silver would be a good plus point. Also, as not having demo-ed anything specific regarding subs recently, how do things compare to my Model 30B nowadays?? Did hear a Mission Elegante sub in use on a projector demo and it sounded good, but out of my price range......... Thanks, Ed.
