Heresy alert: depends on your electromagnetic environment.
If you get good cel phone reception, or there are radio or TV transmitters nearby, chances are that you have a lot of electromagnetic radiation in your environment. Some cables may act as antennas to pick this up.
This interference can be attenuated by a woven shield, by the tight winding of the individual wires, or the configuration of more than two wires. Penalty for this is higher capacitance, which can reduce the high frequency audio signal. For short runs of 6 meters or less, this penalty is insignificant; indeed, for many systems it is preferable in that it reduces high frequency glare.
I did not try to reinvent the wheel. I use shielded, 4 conductor microphone cable in a star-quad configuration: Mogami 2534 or Canare L-4E6S, terminated with ETI plugs. Very cheap and very effective.
