They're just standard Canare 4S11 Star Quad cables. You can get the raw cable from most any place that sells Canare products. They can't do anything to it that you couldn't do yourself cheaper. Get some techflex and heat shrink tubing and you'll have that high-end / boutique look for much less. However, if you don't want to spend the time or the effort, they look like a pretty good deal.
