If you don't mind used, you can get a used Krell 5.1 processor for $500 off ebay these days, and it sounds better than getting a surround receiver as you know.
For speakers, I like Dali Zensors - I wouldn't say they are the next level up from your B&W, just different. I too have B&W speakers - what do you not like about them now?
