Dali Helicon vs. B&W 805 and Paradigm Signature

I've got a pair of Paradigm Signature 2s which I'm quite happy with, but I'm itchy to try some new speakers just for fun. I've heard the B&W 805s and thought they were great, but a different flavor. I'm also interested in the Dali Helicon 300 but haven't been able to do a side by side comparison. I'll probably get a loaner pair to audition sometime soon, but I thought it would be fun to hear what others have to say about the comparison. Those Dali's are fine looking speakers and I'm definitely looking for "better" rather than just "different".
