Up for sale is a modded pair of Fostex T50RP, I bought these new from B&H about 4 months ago.
They have the following mods:
'Plasticine mod', the gaps around the drivers are filled with modeling clay.
'Cotton damping mod', the inside of the driver cups are filled with cotton padding.
'Dual entry mod', recabled with 7ft Mogami 2893 cable, terminated with neutrik 4 pin xlr.
If you want an unbalanced termination I can terminate it...
