It's not an isolator, it's a power source and filter for 5V USB power. Sometimes Schiit takes them selves too unseriously. To call this an isolator is a mistake, and they even mention it in the self-deprecating description/specs:
What about galvanic isolation?
When you talk about galvanic isolation, you’re talking about USB 1.1. There is no galvanic isolation that works at full USB 2.0 speed (480Mbps).
Wait, what?
Oh, you haven’t heard this? Funny how the buzzwords change. There was recently an AES paper about galvanic isolation at full USB 2.0 speed, but there are no commercially available solutions for it. Don’t worry, when and if it’s ever available, we’ll make sure we’re fully buzzword compliant.
This thing is a $99 filter and somewhat upgraded 5V source, an iFi Power without the dual outputs. Not bad I'm sure....just not a galvanic isolator.
Thanks for the heads-up.
That leaves us with the USB3 fibre cable as a galvanic isolator. Should get mine today, as well as the Wyrd.
