Here is what Chris at VH Audio says about the cable in balanced use:

There are so many options when building these that I could not tell you what you will like best. I personally prefer the somewhat larger 23-24awg wire size (over the 28awg some use) and I like using a single wire for pos and neg. Others like doubling up the negative run for single-ended cables, although you should use the same exact wire/awg for each run of a balanced cable. You can also space a shield away from the conductors if needed. Theories vary on whether to hook the shield at one end, or both ends. If you search here, Audio Asylum, Audio Circle and other sites, you will find more information than you need on diy cables.
IME, for a "made from scratch" diy cable, the configuration shown on Chris' website, when used with the caulk backer and high quality connectors, is hard to beat sonically. I used slightly larger caulk backer (I believe 1/2 inch) for even greater spacing of conductors. If you are worried about the durability of the caulk backer, then try Chris' soft teflon tubing.
This cable design also works excellent for balanced ANALOG cables. It is not neccesary (Most of the time) to ground a balanced connection, so you only need to use pins 2 and 3 on the XLR's. In some systems, Pin 1 will need to be connected at both ends, but this is rare....and here is a link to the information;
* In some situations, you may experience problems with RF interference, due to the lack of shielding on this cable. If think you may have an RF problem, check out the VH Audio Pulsar double shielded interconnect here. This interconnect is available assembled, or the wire is available for you to DIY.
