Hi Ozzy yes the lan rover send the signal from box to box but if like me your PC and your amp or preamo are close together then you will only need inches of cable. I will stess tough that Ps Audio say that you can use a mediocre cable from Pc to sending device but I will counter that by saying that two usb cables of the same quality give a marked improvement so I am using Telurium Ultra silver and once they are broken it they give a stunning sound . Just a little bit of patience is all that's needed, I stuck the device through my PC with internet radio playing continuously and after a fornight the sound just seemed to explode out of my phones, I now love it.
