For well below $100 there can be made many feet and many lengths of DIY power cords in excellent quality. For some years now I've been happily using PC's throughout my entire system comprising 16AWG solid-core copper installation wires, bought at the equivalent of Home Depot for a measly $3 per 5x1 meter(where each wire is individually insulated and then bundled under one outer sturdy insulator, which requires some stripping/cutting work to free the individual wires from the outer "casing"). The coppper quality is top notch, despite what may be claimed to the contrary, and though the insulator is PVC I'd not worry about it, seriously; much more important is that the wires are not stranded but SOLID-core. The lead and return wires are twisted(~3 twists per 4 inches) and the ground wire is then twisted around these in the opposit direction. Each length of power cord is a little over 7 feet. The power cord from the outlet is heavier gauge 14AWG solid-core installation wire due to some 15 feet run, constructed the same way.
I urge you to try out the above. It requires a little work, but it's cheap as hell and I'm fairly certain the sonic result won't disappoint, making for a true cable-bargain and loosing no sonic face to much more expensive alternatives I've tried.
