Ruby Signature analog interconnects are meticulously hand-crafted and are the pinnacle of Purist Audio Design's cables in luxury and sound! They are fashioned using 20 AWG silver-plated Oxygen Free Copper and surrounded by Purist Audio Design's proprietary Ferox® dampening material. Analog interconnects come in a stereo pair, one left cable and one right cable. They are available with RCA terminations or XLR terminations using Furutech’s Carbon Fiber Rhodium NCF connectors. Available lengths start at 1.0 M (3.3 Ft.) and increase by 0.5 M (1.6 Ft.) lengths. The Ruby Signature analog interconnects are directional, and the arrow indicates the direction of the signal.
