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 greatest sources of distortion, often causing a somewhat hard and dirty sound. Solid conductors are fundamental to obtaining the natural, clean sound of the Red River.
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.

Good sound and good build quality. This cable maintains the level of quality between the devices it connects.

After two months of use, I can confidently say that this RCA cable represents a significant improvement over entry-level "red and white" cables. Additionally, I have other devices connected with QED Reference 40i cables, which perform identically to the Audioquest.
Conclusion: Excellent product.

Very good balance, treble, midrange, and bass.
