You will get a lot more "music for your money" by upgrading the speakers. 803s would be a nice upgrade and there are a couple pairs on Audiogon right now for around $3500. You might also consider the KEFs and Spendors if you like the British sound.
And, I would be remiss if I didn't put in a plug for the speakers I am currently using (and expect to use for the next 5-10 years): Gallo Reference 3. They are not as physically imposing as the B&Ws (a point in their favor for you), but they can sing with the best of them. Grab a gently used pair of 3.1s here on Audiogon for around $2200 - $2500, add the Gallo sub amp (typically $750), and you will have one whale of a good sounding system. And, the WAF is quite high if you leave the grills in place. My wife thinks that they sound mighty fine and look good, too.
