======================================================

Again, there is much debate over the benefit of the various schemes

that are being used by different manufacturers. In general, however,

you will probably want to upgrade your speaker wire from the factory

~20 gauge to something bigger when you upgrade your amplifiers and

speakers. In most cases, 16 or 18 gauge should be sufficient, with the

possible exception of high-power subwoofers. According to an example by

Jerry Williamson, using 18 gauge instead of 12 gauge would only result

in a power loss of 0.1dB, which is essentially undetectable by humans.

Thus, other factors play more important roles in the selection of

speaker wire. One issue is that different wires will have different

line capacitances, which could cause the wire to act as a low pass

filter. Generally, however, the capacitances involved are so small that

this is not a significant problem. Be sure to heed the warnings above

regarding cable flexibility and insulation, especially when running

wire into doors and other areas with an abundance of sharp metal.
