Your best bet with anything like this is to leave that choice to the professionals. In other words do not look for shielded or unshielded. Don't give it a moments consideration. Look only for what sounds good.
Other than phono cables where the signal is in millivolts so must be shielded its unlikely you'll find a shielded interconnect you prefer. But if you do, buy it. Buy the sound not the theory. Every. Single. Time.
