This is a bad idea in general, but especially for Touch. You need regulation at the point of load because CAT5 has a high resistance (3 ohms / 100ft) and Touch draws highish, variable current at only 5V. Even if it appears it to work on a shorter cable run, you could get compromised sound quality (due to clipping and/or noise) or you might even get intermittent crashes when load current increases. You will probably find it gets worse when USB devices are connected. And you can't just increase the source voltage to compensate, because the load is not going to be constant. If you're going to do POE, use a proper regulated splitter. I would not suggest the "passive" trick for anything more sophisticated or expensive than a light bulb. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=68178
