Digital coaxial advice needed

Can you rephrase your question? Not sure what you are asking. PC's? Personal computers, power cords or?

I look for a coaxial cable first hand. To connect the devices.
I have other balanced IC’s, so i am set here. Perhaps i look in to PC’s later, but there are other things first.
I have been looking at rows of cables, but Lessloss seems interesting.
Perhaps a bit expensive

Sorry, PC's = power chords 

I'm still lost with your request?  You have 2 pc's that you want to connect to your nuprime, correct?  Your nuprime only has 1 usb input.  Why not pick up a SPDIF converter.  One of your pc's will go directly to the nuprime. The other pc will go to the SPDIF and then into either the coax or toslink.
