If shielding is a concern, and it should be, look for a foil shield for any reasonably permanent installation. Even the best braided shield tops out at about 95% enclosure, foil (properly implemented) is 100% and, if a drain wire is supplied, makes soldering much easier. The downside is that if the foil ever separates (from excessive flexing, etc.) it makes a wonderful antenna thus defeating its purpose.

I roll all my own interconnect, but I tend to stick with (foil) shielded twisted-pair for my baseband audio. This allows me to use the same stuff for balanced and unbalanced connections and since the package is thinner it looks and routes better. At work, we have to concern ourselves with fill density; at home, it's more about "that rats' nest behind the stereo."
