HDMI can output 24/192 without a problem, this is something than NO motherboard spdif output can do or any usb that I know of...
Now-a-days many motherboards have a HDMI out, so how about using a HDMI to SPDIF converter instead of a USB to SPDIF converter?
After all HDMI is "made" for audio and video, unlike USB which has only been adapted to serve the needs for audio, but was made for keyboards, printers, cameras, etc.
Like this....HDMI in one side and video out for your computer monitor out the other side "Plus" 24/192 audio out for your Dac.
