Here's my version of a no-nonsense interconnect cable:
The real reason why I didn't use any nylon braid was that when I heatshrinked it onto the cable it wouldn't fit inside the connector

An excellent cable in any case, and although not as classy as it would be with nylon braid, I actually like the dark green colour.
Here's a short braided cable I made to find out if braided cables are any good:
The wire is 20 AWG tinned copper. My regular interconnects are made with the same connectors and Tasker C850 cable (two strands of 24 AWG silver plated copper wire and external shield). When I compared these two there was a slight difference, with the braided cable providing a bit more bass.
This cable was however too short for regular use, so I dismantled it and used the connectors elsewhere. I'll probably make a longer one sometime in the future and test it with my new CD player.
