B & W 600 series
When shopping for speakers I went to a high end store in my area (Chicago area) and listened to a 5.1 setup which consisted of: fronts: B&W 685, Center: HTM62, Rear: 686 and an ASW 608 sub.
The sub was not very impressive. The 685s were very nice and detailed, but they didn't blow me away. We spent about 90 minutes listening to music and movies.
I opted for internet: my system is Hsu - and I'm quite pleased with it. The B&W system I auditioned would have cost more than $2000 plus Illinois sales tax. I got my Hsu 5.1 system (see my signature for details) for about $500 less.
Of course speaker preference is VERY subjective and you may love the B&W sound. Also, I don't know what price range you're looking at.
