For a reason Clay stated and that is not using the shield as a current
carrying conductor in audio, I use a 3 wire shielded cable for all my
mike applications, ham radio and professional. There are several good
brands, Alpha, Belden, and others. Also Heil has some cable which is
suitable where audio and PTT circuits are required.
A single conductor shielded cable is not suggested. As to where to
find and buy a good Foster connector, I haven't found a good source. As
to other connectors such as the XLR series, I find Neutrik to be the
preferred brand or Amphenol as a 2nd choice.

In my experience, the best microphone cable stock currently existing is Canare
Star Quad cable.
I'm on my phone, so don't want tp peck out a complete answer here and now.
Star Quad cable has 2 twisted pairs and a shield and is nice and flexible
broadcast quality cable stock. Has great endurance.
I use it for my microphone, key, and any other cables I can. There are at
least 2 sizes now.... Get the largest wire gauge available. Consider putting
some on your shelf for future use too.
I use a condenser mic so my wiring may be different, but I would never use the
shield as a signal wire if I wasn't forced to.... Use the twisted pairs to
your advantage.
Can't help on the multi-pin connectors, as I don't use it at all. But find and
use the best ones tou can find.

[Elecraft] K3S Microphone Cable
I am remaking my SO2R control box cables and I need to purchase quality
microphone cable however I am not sure what to get. I am using an electret
microphone. I assumed that I would need a cable with a single conductor and
a shield but most mic cables that I see have two conductors. Belden has a
single conductor
http://www.awcwire.com/mfg/belden/product/belden-high-impedance-microphone-c
able but it's a high impendence cable and the Belden multi conductor cables
are all low impendence. Does that matter? What gauge wire should I use for a
5ft cable? I would appreciate any suggested cable models or feedback. I am
also having a difficult time locating brand name quality 8-pin Foster mic
plugs (I prefer using the front jacks).
