Just got the SRC-DX in this morning (thank you Nick!)Audiowise are claiming that bypassing the USB clock lowers the overall noise and that has an impact on sound quality. They also claim they are filtering the noise, but since people are still using Wave cables with them, or the Opto-dx, not that well probably. There is still probably less than non isolated usb power lines out of a gaming pc.
It sounds like an Intona in front of the SRC-DX might be the way to go unless you have any other suggestion. I was really hoping to get rid of the cables and boxes on my desk.
Confirmed that it does NOT have galvanic isolation internally and the USB input/BNC outs share a ground connection, so you may wish to add a galvanic isolator to prevent noise from the source/PC getting through.
The device itself is pretty low noise though so if you have a clean source to begin with or an isolator you're good
