There's a pair of Silverline Preludes for sale here a little over your price range that have the sound characteristics you are seeking and are better looking than the Kefs and definitely the B&Ws -- Ick. Best of luck.
Advice: used speakers $600
Choices: PSB stratus silver,Kef 104/2, B&w Dm7 mk2...any clear cut winner? I prefer a smooth, balanced sound, open midrange, controlled bass over extension.Also, which one of these requires the least maintenance in terms of upkeep.
