It's an interesting question. All cabling is important obviously, but the tonearm cable is probably the one in my system where the differences in sound quality seem to be more extreme and easier to hear as opposed to speaker cabling, IC's or power cables.
And, incidentally, that is running fully balanced into a balanced/differential phono preamp with both balanced inputs and outputs so I don't buy into the idea that the cable is less critical in that application with a balanced phono pre. In my experience, that is not true.
