I want to use my Nuforce Icon as my primary music system in my living room using a pair of Paradigm Atom speakers and therefore need to extend the length of the standard Icon speaker cable. I thought I should use a RJ45 coupler and buy new ready made cables instead of creating my own cables. My question is, what kind of cable should I use? CAT5, CAT5e, CAT6? UTP (unshielded) or FTP (shielded)? I have read somewhere that if the product is not connected to a grounded power outlet, using a shielded cable could result in even more noise/disturbance from the cable compared to an unshielded cable. Could the wrong type of cables even damage the Icon? What kind of cable do you recommend?
