B&W all the way. I had the same setup and I loved it. I think they are a great speaker and they can be had in your price range.
Kinima G1 from Zetagcorp. I have mine with an Audio Aero amp and cdp and Cardas wires. Go to the website or google for info.
Joseph Audio RM7si or Tyler Acoustic Taylo refs both about $300 more or less above your range, but a significant improvement over midline B&W's IMHO. I pair my JA's with Jupiter2000 and I5. Love it!
