You are picking up electrical noise from the USB power from the PC to your DAC, and the SP200 is amplifying it. The DX7 is doing a better job of filtering it.
Solution: a USB power isolator, like the iFi iDefender3.0. Or connect the DAC to a self-powered USB hub. (This will most likely just lower the noise)
If I connect to a self powered USB hub, then don't I still need to connect it to my PC? Don't you have this issue too ? My motherboard is the Asus Rampage Extreme VI Encore
