In my experience with USB C - 6 feet is fine but a 10 ft cable apparently starts to weaken the needed signal and you may start to see issues.
Does USB cable length make a diference?
I'm not talking a super long USB cable. I'm looking at a short usb cable from my Streamer to Dac (1 foot would even work). However if I got a more standard length (2 to 3 ft) would I lose anything? A longer cable would be more versatile if I ever needed it for soemething else.
