AudioQuest spent the last several years designing new replacements for its high-performance and high-value interconnects. Introducing Mackenzie . This cable is a magnificent performer and worthy of recommendation. New connectors and pins, all big improvements. A triple-balanced design, Mackenzie has a separate ground conductor to keep noise at bay. Polyethylene foam or air tubes insulate the conductors. And a new triple-layer noise dissipation system further protects the delicate signal from RF interference. Mackenzie uses Perfect Surface Copper+ (PSC+) , which has less grain structure and a polished surface to reduce distortion.
