I understand that this Corning cable does not provide true galvanic isolation (which can be essential in resolving some system noise issues) due to some power wiring that follows the glass fibre signal conduit. Another kind of USB device that may provide this kind of isolation may be those devices known as "USB over CAT5 extenders" such as these: http://www.tripplite.com/product/usb-over-cat5-extenders/870. Since they don't have a separate power supply at the far end, as they stand they may not provide full galvanic isolation, it might be possible to determine which wires in the CAT cable are carrying power, and cut them and insert a separate USB power supply for the far end. This device has remote separate USB power and may provide better isolation (or not): http://www.amazon.com/CAT-5E-CAT-6-Extender-Power-Adapter/dp/B0026RKUBY Just thinking! ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=103583 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
