You can absolutely go to Home Depot or Lowes and get the wire you need,
economically, and it will work every bit as good as the "audiophile" stuff.
Wire, is wire as long as the gage is sufficient for the distance of the
runs.

Now I have not shopped either store for a while (still have plenty from my
last wire shopping visit), but you may wish to consider that one of the two
stores (can't remember which, I think it was Lowes), sells their 12 gage
speaker wire wrapped in thicker insulation with thinner strands than the
other vendor. This serves two purposes: a bit easier to work with and it
looks "cooler" laying on your floor giving your installation that "with it"
high-end audiophile look much sought after in some circles. Alternatively,
you can buy either wire and run it through some garden hose where it's
visible to get the "very serious audiophile" look.

In addition, get the speaker cable that Quad recommends... Black &
Decker extension cord. Of course, you will have to "mod" it. Cut off the
electrical ends and add your own speaker connectors. Of course, you'll
have to like the color...
