From the beginning, AudioQuest has been a pioneer in using superior quality metals, but we were surprised by the leap forward in performance achieved with the incredibly smooth and pure surface of Perfect-Surface Copper (PSC). PSC clearly outperforms previous AQ metals that cost more than ten times as much. The exclusive metal processing technology protects the wire surface at every stage of drawing and manufacturing. When the high-purity, low-oxide copper is as soft, pure and smooth as possible, it becomes a very low distortion conductor. In a conventional cable, the electrical and magnetic interaction between the strands is one of the biggest sources of distortion, often resulting in a somewhat harsh and dirty sound. Solid conductors are fundamental to achieving the natural, clean sound of the Red River.
Cold-Welded Gold-Plated Termination
This plug design allows for a solder-free connection, which is a common source of distortion. Instead of soldering, the process uses a high-pressure technique. Because the molded shells are stamped rather than machined, the metal used can be chosen for low distortion instead of machinability.

The listening quality is quite good and matches what you’d expect after reading reviews and comments in the press and specialized forums (product not auditioned before purchase).

la qualité d'écoute de bon niveau correspond bien à ce à quoi on pouvait s'attendre à la lecture des avis et commentaires dans la presse et les forums spécialisés (produit pas écouté avant son achat) .
