Regarding the NAD cans, they are really good. I got to spend some time with Jude's pair (the guy just has every headphone under the sun) at RMAF. My impressions were the mids are a bit polite and slightly laid back kind of like momentums, bass deep and tight with just a slight warm upper bass and lower highs, like Tyl says, slightly prominent but fantastically delicate. Aside for the mids being a little further back than I would like, they are very good indeed. Reminded me a lot of a Senn 650 type signature.
I would rank the NADs just lightly behind the Sony 7520 and Focal Spirit Pros (for my tastes) but have never heard the KEFs or B&Ws.
