I also make most of my own cables. My studio is outfitted with Mogami, Canare and Horizon cables mostly. I also like Connectronics cables a lot, the Musi-Flex line.
My feeling about cables is that their effect is cumulative. If you only have a few cables, then you can get away with lower quality perhaps. But if you have a lot of cables, the quality has a bigger effect on the sound. It's subtle, but I certainly believe it's audible.
So the short answer is to get good cables, but don't go crazy buying ridiculously expensive audiophile stuff. Cables made with Canare or Mogami wire are going to be plenty good enough.
