I'm with Rlwainwright, if you love the B&W sound, the 805 is a great option. They're easy to find, plenty of supply on the secondary market, and they hold their value very well so even if you were to change things down the road you'd get back 80-90% of what you spend on them. I understand the urge to try new things, branch out and try new brands, but if you love the 803 sound then sticking with B&W and going with the 805 may be the bird in the hand...
