Ieales is right. Just plain right.
Take, for example, my ESL speakers. They come with a resistor in series with the cable to tune the transformer. So, you might ask, why bother with an ultra-low resistance cable? Answer: you shouldn't. You should lose that resistor and engineer the cables to have the required resistance (and other properties). Good luck with getting that off-the-shelf, but you'll find lots of people who have firm opinions on the 'best' cables for all speaker/amplifier combinations.
As for starting with something good, why? By which criteria are they good? I say start with lamp cord, and make every upgrade prove itself in your system. But if you must spend money for whatever reason, try Goertz cables - they are most nearly neutral (by Maxwell's Equations - but then who cares about the science), and can best withstand long runs.
