Not sure what you're budget is, but a quick google search shows the B&W setups aren't cheap...
So I'd say - Paradigm MilleniaOne.
To date, they are the best tiny speaker I've heard, understanding that they can't really play bass frequencies.
If the speakers don't have to be tiny... the PSB Imagine Mini and Imagine Mini Center could be worth a look, or even the cheaper Image B4/C4.
