Keep in mind that the shield of an unbalanced interconnect not only reduces emi/rfi pickup, but must provide a connection path that is as low impedance as possible, in order to minimize pickup of low frequency hum and high frequency buzz due to common impedance coupling from ground loops that may be present to some degree. And that requirement is generally much more important than shielding against airborne pickup, as explained in this paper:

The coiled construction of the return conductor of the Anti-Cables interconnects leads me to wonder if their impedance at high frequencies, due to the resulting inductance, may lead to unacceptable ground loop problems in some setups. Particularly if the cables connect components that are plugged into separate dedicated ac lines, or ac outlets that are independently filtered by power conditioners, and particularly if high frequency distortion components (such as may be caused by dimmer switches, for example) are present on the ac line.
