I actually think power and speaker cables are fun to build. Others not as fun. For power I use DH Labs (Silver Sonic) top-end red bulk cable for amps and the one-rung down "Power Plus" for everything else. Wattgate connectors appropriate for the usage. I don't put braided sleeving on them because the stock cable's finish is easy to wipe down and power cables tend to get dustier than others.
