Based on your criteria, you should also look at PMC fact.8. You should be able to get these in your price range new and they have excellent clarity and are wonderful with the type of music you listed. I have a pair in my bedroom system and work well with a variety of sources.
I have KEF Reference 5s in my dedicated listening area and, while amazing speakers, I don't think they pass your WAF requirements :) The fact.8s are small, but project a wide sound stage that belies their size.
