I've always wanted an ASW675 since I got my speakers, which are as follows: Mains B&W DM602 s3 Centre B&W LCR600 s3 Surrounds B&W DM601 s3 I've got a reasonable sized room which is about 5m x 3.5m, 2.7m ceiling. A second hand ASW675 is comparable in price to some of the newer B&W subs available on the second hand market, so I'm wondering how they compare in terms of performance. I'm a fan of multi channel music (SACDs etc) so both music and movie performance is important to me. I like the idea of matching my speakers and am a fan of the B&W brand (hence my preference to B&W) and I also like the look of the 675... What I would appreciate is any feedback anyone can give me that has owned a 675 and has been able to compare it directly with any of the newer models. Thanks in advance, Charles.
