The isolator needs USB compliant cables. Often, "audiophile grade" cables have the screen or even the ground wire disconnected on one side. This is not compliant at all and this cannot work with galvanic isolation because the isolator breaks the shielding and ground by design and doing this twice is impasse. Sometimes those cables have a wrong wave impedance (more than 50% deviation of 90 ohms differential mode and/or 30 ohms common mode).

Further, disconnecting the shield within cables is just silly because it does nothing, nothing, nothing for "better audio" but it rather acts as a very good RF antenna for both receiving and broadcasting noise (and your data as well. So it will become easy to intercept or spy out your most intimate secrets within at least 100 meters).
