Although building your own power cables won't really save you money, it can increase the efficiency of your system, at far less than professional prices.
One of the less known, but well-respected, terms in home theater is clean power. That's usually the term reserved for high-end power cables that are getting the maximum amount of power to your components, in the most efficient way. Of course, the cables that come with most components don't function at this level, and it's incredibly expensive to buy power cables that do. For the electrically inclined, though, the DIY route provides a great alternative: make your own power cables!
There are a variety of approaches to power cables; several different designs are supplied here, each optimized for different applications. Additionally, a fair bit of electrical knowledge is assumed. If the instructions confuse you, you're probably not to the point where you should be playing with power cables anyway!
The parts list is identical for both flavors of power cables.
