    As he correctly points out, properly designed ones can be useful *if* there is no galvanic isolation on the DAC's USB input. If this part is well-sorted, then an extra box is only going to increase noise, even if slightly / inaudibly.

    I've even heard of people daisy-chaining these units together, oh dear!
