Longest USB cable length to DAC for audio?


Recommended Posts

USB 2.0 specs state 16 feet is the longest the cable should be w/o a powered hub in between the lengths.

Strictly speaking, the limitation is 26 ns. With a typical signal propagation speed of 0.2 m/ns, the maximum length becomes 5.2 m or 17 feet.

 

😉You don't have to go all technical :D

Purchased a 3 meter Granite Audio USB to hook up quad core Mini and Mytek DSD192 and it had a very detrimental effect on sonics.

 

It worked, as in music played but sounded bad (messed with cymbals, other percussion...) versus a 1 meter cable.

 

Returned the 3 meter.

 

Just remember that a certified USB cable has specific characteristics and is tested to work the way it does. Might have been a bad USB cable.
