The Monitor Audio BR2s (on decent stands - think £60ish for Soundstyle Z2s at least) would be a good starting point, but the BR5s - or KEF's iQ5SEs for the same money (£400) would be a step up in balance, detail, dynamics and low-end presence - as you'd expect for something in the next size/price class up.
By the B&W 385, I assume you mean the 685 that costs £380? These - on £100+ stands, such as Partington Dreadnoughts - are awesome for the money. I'd strongly suggest you audition them against the KEFs and bigger B&Ws if your budget allows - as you don't mention the size of your room or the positioning your speakers will be/need to be in, there's some flexibility here.
Any of these three speakers would also be happy on the end of higher-level electronics that your (excellent) pair, giving you an upgrade path....
