How important for the sound quality is the USB cable when using a USB/SPDIF converter like Audiophileo or JK HiFace?
I think you should go with the best USB/SPDIF converter you can afford (V-Link -> Audiophileo 2 / JK SPDIF mk 3 -> HiFace Evo + Evo Clock + PSU) and only after that try different USB cables. IMO this brings greater improvement that replacing the USB cable.
