Hi, I'm selling my Alpha Design Labs(ADL) iHP-35Hx-XLR cable in excellent condition. ADL is a subsidiary of Furutech, and iHP-35Hx-XLR is ADL's flagship balanced cable for the HD800. It uses cryo-treated OCC copper wire and comes with Furutech's most expensive rhodium carbon fiber plugs for both ends. I won't really comment on its sound as I had no other balanced cable to compare it to. The HD800's stock cable is single-ended, so it won't be a fair comparison anyway. I've used it with my DNA Stratus/HD800 for about 2 months. Price for a new cable is $431. I'm selling it for $250. https://www.thecableco.com/Product/iHP-35Hx-XLR-Headphone-Cable Please send me a PM if interested.
