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. I've used it with my DNA Stratus/HD800 for about 2 months, and all I can say is that driving the HD800 balanced with iHP-35Hx-XLR sounded better than driving it single-ended with the stock cable. 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.
