I suggest that you consider the Definitive Technology Studio Monitor 55 speakers. They cost $600 per pair and are excellent.
Stereophile did an article on them recently, and they almost ran out of superlatives in describing them.
There is no question in my mind that they sound better than either of the B & W speakers.
You should always listen to what you want to buy IN YOUR HOME with your amplifier and acoustics for at least 2 days; there is NO substitute for that. Any dealer that won't let you either borrow them or buy with full refund privilege isn't worth spit.
Another pair of speakers that are better than ANY of them are the Anthony Gallo Classico CL-2 speakers, which will run you $800 for a pair. The Absolute Sound did a very informative and flattering article on the larger CL-3, which I tried and bought and absolutely LOVE...lol!!!
Gallo will give you a 60-DAY FREE HOME TRIAL, with no obligation (if you return them you pay nothing; they pay shipping both ways) No risk there. Nothing is half as good as trying them in your own home with your equipment and acoustics (especially for a month or more).
