After much deliberation I've decided to part ways with my HD800. I purchased it essentially new from a local friend about 2 years ago, who had only 5 hours on the headphone. No smoking, pets, etc. There are some small cosmetic marks on the corners of the paint (see pics). The headphone works perfectly and I am just trying to thin the herd due to an upcoming speaker build. Unit# 24066 The headphone is modded. It currently has the creatology trapezoid piece, rug liner and a trimmed large Shure Olive tip in the center as a resonator - aka the V1 "French Mod". The protective screen in the hollow center of the driver has been cut out and removed to allow easy swapping and testing of various resonator mods (see pics). I am dropping the total asking price a bit due to this, but it may actually be advantageous if you want to try out various mods as time progresses. I can include some modding supplies as well if desired. Shipped CONUS, I'll cover the paypal fees: $750 with stock 1/4" cable in the original box - $150 extra to also include the Norne Draug 2 cable described below. Also available: 8' Norne Draug 2 cable with Eidolic 4-pin XLR termination, black and gray wiring - First purchase opportunity will go to the headphone purchaser. If they don't want it, I will create a separate post and sell it individually. Norne Draug 2 cable - Available for the additional price listed above.
