Just for information: the TotalDac D1 USB cable does not provide galvanic isolation. There's only two "ready" products at this moment (Intona and Coolgear) that offer full galvanic isolation for high speed USB 2.0 (480Mbps). Others (mainly DAC makers) that say they offer it don't isolate USB itself but somewhere upstream after the PHY and the USB chipset like XMOS for example in an I2S link tying into the DAC. Of course this is better than nothing but not not the same or as optimal.
If I'm not mistaken, the Mutec MC-3+ USB also offers complete galvanic isolation on its USB input.
