In this case you also have to do something about the signal wires, and provide a power supply with a separate ground. The Corning optical cable addressed the signal wires, but seems to have blown it with the power wires. My idea was to go down a separate somewhat older but still widely used path: Transformers. USB Baluns for CAT 5 go down that road. Just have to get one with enough bandwidth, and a separate power supply for the far end. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=103727 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
