There are a ton of threads on the Senn replacement cables over at www.head-fi.org. I believe the Equinox come standard at 9 feet and price at $190.00. Additionally, Zu cable has recently come out with the Mobius, which many seem to like. They have recently been running an introductory offer. A less expensive option is Jan Meier's upgrade cable at about $60.00. Its tough to find someone looking to sell their upgrade cable separately. Good luck.
