Gauge really only matters for current. Things like stranding, cladding, core materials, etc can matter more for other usage.
But for audio, use whatever you feel like. I typically buy used snake cables so I can remove the smaller differential cables out of it and use them for wiring stuff with shielded wire.

When does the wire require shielding? |

When does the wire require shielding? The really short answer is, I'd do it whenever you're wiring a lot of stuff inside the box. The longer answer is, it's hard to say. It depends on the noise, the EMI/RFI fields, the installation location, the type and power of the signals, etc. If you're wiring something like an 1176, with lots of wires and high impedance audio signals, then it's almost required to use shielded cable. |

Got a shielded cable that you recommend...other than used snake cable? I need to extend some leads from my output transformer to a T-Pad in my Sta Level. Then from there to the resistor attenuator network. |

I just use shielded everywhere, and i also cordon off my PS section with some ferrous metal, it's a tiny bit of extra work, and cost, but it's miniscule for the peace of mind, and resultant low noise floor, i hate PCB layouts with the PS on the same board as the audio, a daughter card is the way to go, i often wonder why i don't just build the PSU completely outside of the rig in it's own box...

Then from there to the resistor attenuator network. I don't have a specific one, but I always use cable that has both a stranded ground and foil shield. Seems to work in pretty much all cases. |

For hook up wire I use military surplus silver/teflon or Kimber pure silver. Shielded wire is Mogami AES/EBU mini pure copper stranded. It has lower stray capacitance than audio grade wire. I also have some silver/teflon shielded cable from Rockwell, it was used on the space shuttle.
