I would take a look into Ultrasones, Denons, and Beyerdynamics. Depending on whether you're a basshead (and even more specific - sub vs. mid vs. upper bass), looking for clarity in mids, treble brightness, open vs. closed designs, etc. Also, do you have or will consider buying an amp? Do they need to be portable or isolating? How important is comfort? Reading up on some threads comparing the Ultrasone Pro 900 vs. Denon AH-D2000 vs. Beyerdynamic DT-770 Pro 80-ohm would be a good start, for example.
I currently use the Ultrasone HFI-780 for electronic music and have ordered the Ultrasone Pro 900 as an upgrade. They're renowned for electronic music in general, and almost perfectly match my requirements, but may or may not fit your specific needs.
