You might want to ask over at http://www.head-fi.org/. The Orpheus is rumored to still be available under the right conditions from Sennheiser. It is an amazing looking piece of gear, sort of like an altar. Heh, at least I saw God when I looked at pictures. Depending on your tastes an Omega 2 with a Blue Hawaii is rather amazing and probably in the same league if you like electrostatics. The Sony R-10 is also a great headphone and rounding out the trimuverate of the top cans would probably be the HP-1000 series driven with the proper amplification.
