I was hoping to get a little confirmation from fellow owners of the DI-V3 and DI-PSU. I recently DIYed a usb cable with the VBUS or 5v wire severed. When I compared the diy wire to a standard usb cable the DI-V3 had a much more analog sound. I asked Kingwa about this since he told me before I bought the DI that it wouldn't use USB power if attached to the PSU:
"The DI V3 don't use the +5V wire while use extra PSU.
I was hoping we have a few diyers who can also test this out. The 5v wire is either red or orange in standard usb 2.0 cables. If we have enough confirmation of what I was hearing then we would have a real easy way to further isolate our dacs from computer noise since the DI truly needs no usb power to operate its clock unlike a lot of other USB audio solutions.
