Up for sale today is the stock cable from an SR80 ($OLD shipped and paypal'd to anywhere). The cable is just under 7 feet long, and in great condition, but the first owner had the cable sloppily reterminated with a dubious-looking 1/4" connector. I replaced the connector with a random, durable 1/4" plug that I had lying around (lol), but the connector has not been sealed so you can desolder it easily if you wish. I can shorten the cable and turn the leftover into an extension for an extra $7 (Neutrik 3.5mm M + F connectors). +$14 instead for Neutrik 4-pin XLRs, one male, and a female, so then you get a balanced cable + balanced-to-single-ended adapter.
I can recable your headphones with this nice cable if you send them to me, and at no additional cost other than return shipping. I don't want to have to deal with wooden cups, however.
I am willing to trade for cotton sleeving, Neutrik NYS240BG or NYS373, Switchcraft RCA or mini plugs (chrome or black, doesn't matter, but gold-plated preferred), or DoubleHelixCables plugs.
Feel free to ask me any questions.
Thank you for looking! n__n
