Hi i would just explain better what i did
With reference to the picture i cut the shield, red and black wires leaving connected only the white and green and the dac worked without problem and i did not notice any difference in sound honestly
So i guess at least in that case a usb power supply will give no benefit.
Instead i am quite sure that it would give big benefits to those usb dacs relying only on usb power to work.
But if there is a galvanic isolation ... a better usb power maybe it is not needed.
Still i would like to have a usb dac able to work only with a usb data only cable ... as a principle.
Kind regards,
