I would find a place where you can check out the AKG K or Q 701's or the K702's. I think they're the best value and can be had new for about $250 new in some cases. OR if you're willing to waste some money on the shipping if you don't like them, there's a set of K701's ($195) and Q701's ($210) for sale here right now. They're already broken in, and would let you make a more accurate decision as to whether or not the sound is for you. (If you can live with the green color I would get the Q701's as you can switch out cords and AKG always tweaks their drivers, so they might sound a touch better).
If that sound doesn't work for you, then the closed-back Denon AHD-7000's may be for you. Sennheiser, Audeze, and Stax are all good products as well.
