USB standard allows for hot-swapping. There are 4 wires in the USB cable/connector - 2 for power (+5V, GND) and 2 for differential signal (D+, D-). If your DAC is self powered than it will be better to use 2 wire USB cable with signal wires only (to reduce electrical noise). In any case +5V is short circuit protected.
Connecting laptop to dac via usb- gear on or off?
I’ve been told to only connect my laptop, a MacBook Pro, which is where all my hi res music is, to my dac, with both the computer and dac off. Connection is via usb.
Anyone else heard that or do that? I was advised that plugging in the computer while on can cause dac issues-
thanks!
