I've never been one of those audiophile types who felt like I needed all my cables to be super expensive one gauge 2" thick cables that cost $35 a foot. But when I had the opportunity to try some of these pricey Zaolla cables I figured, "Why not?" The packaging that came with it extolled the virtues of Zaolla's solid silver in it's cabling. Apparently copper has only 29 electrons to silver's superior 47 electrons which means it's less resistant to current flow. Their 99.9997% pure silver cable is also resistant to corrosion on the planet Earth while copper isn't. Zaolla cable is only corroded by sulfur, which I'm pretty sure is only found on the planet Mercury, but then again I never did well in science classes.
