AudioQuest Cappucino uses solid-core, 10% silver-plated conductors to ensure that every bit of picture and sound information reaches its destination. Silver is the most conductive metal; silver-plated copper conductors are ideal for very high-frequency applications, like HDMI audio and video. Because these signals travel mostly on the surface of the conductor, Cappucino's high-purity silver plating provides performance that's close to that of a solid silver cable, but at a lower price.
