AUDIOQUEST Red River RCA Cables

The AudioQuest Red River RCA analog-audio cable is designed to provide premium performance at outstanding value. Perfect for connecting audio source components to amplifiers and receivers, it features Solid Perfect-Surface Copper+ (PSC+) conductors that reduce distortion for precise signal transmission. The inclusion of Foamed-Polyethylene insulation maintains dynamic contrasts, while a Metal-Layer Noise-Dissipation System effectively eliminates high-frequency noise. The result is a richer, clearer sound that brings out the natural beauty of music with remarkable accuracy.

Solid Perfect-Surface Copper (PSC) Conductors

The AudioQuest Red River RCA cable utilizes Solid Perfect-Surface Copper (PSC) conductors, offering a significant leap in audio performance. Thanks to proprietary metal-processing technology, the copper’s surface remains exceptionally smooth, pure, and free from distortion-causing imperfections. This ultra-smooth surface minimizes grain boundaries, allowing for cleaner signal transmission and a more natural, detailed sound. Unlike conventional cables that use stranded conductors, which can introduce electrical and magnetic distortion, solid conductors eliminate strand interaction, reducing harshness and delivering clearer, more accurate audio reproduction.

Direction-Controlled Conductors

The AudioQuest Red River RCA cable features Direction-Controlled Conductors designed to optimize audio performance by effectively managing noise dissipation. All drawn metal conductors possess a non-symmetrical grain structure, which can impact signal transmission. To counter this, AudioQuest carefully determines the correct conductor direction by listening to every batch of metal used, ensuring that RF noise is directed away from areas where it could cause distortion.

Arrows clearly marked on the connectors indicate the optimal signal path, aligning with the precise conductor direction and the non-symmetrical attachment of the shield and ground. This attention to detail is a key element of AudioQuest’s Noise-Dissipation technology, resulting in a cleaner, clearer sound and improved full-system performance.

Metal-Layer Noise-Dissipation

The AudioQuest Red River RCA cable incorporates a Metal-Layer Noise-Dissipation System that ensures cleaner, distortion-free audio by effectively managing radio-frequency interference (RFI). While achieving 100% shield coverage is straightforward, preventing RFI from affecting the equipment’s ground reference requires more advanced solutions.

Unlike traditional shield systems that absorb and drain noise to the ground—potentially distorting the critical reference ground plane—AudioQuest’s Noise-Dissipation technology goes a step further. This system "shields the shield" by absorbing and reflecting most RFI before it reaches the ground layer. The result is a cleaner signal path, delivering clearer, more accurate sound with minimal distortion for an enhanced listening experience.

Hard-Cell Foam Insulation

The AudioQuest Red River RCA cable uses Hard-Cell Foam (HCF) Insulation to ensure precise signal-pair geometry and minimize distortion. In any cable, materials surrounding the conductor can absorb and release energy, causing signal distortion. To counter this, AudioQuest employs nitrogen-injected Hard-Cell Foam, which forms air pockets within the insulation.

Since nitrogen, like air, does not absorb energy, it prevents energy transfer from or into the conductor, thereby reducing distortion. Additionally, the rigid structure of Hard-Cell Foam maintains the stable positioning of conductors along the cable’s entire length, ensuring consistent impedance and cleaner, more accurate sound reproduction.

Triple-Balanced Geometry

The AudioQuest Red River RCA cable features Triple-Balanced Geometry, ensuring exceptional signal integrity and low-distortion audio performance. Unlike conventional cables that use the shield as part of the signal path, this design incorporates a dedicated ground-reference conductor, ensuring the shield is never relied upon as an inferior conductor.

Whether terminated with RCA or XLR connectors, the three-conductor configuration guarantees that both the positive and negative signals benefit from equally superior, low-distortion pathways. The result is a cleaner, more accurate sound, with improved dynamics and clarity across the entire audio spectrum.

Cold-Welded, Gold-Plated Terminations

The AudioQuest Red River RCA cable is equipped with Cold-Welded, Gold-Plated Terminations to ensure optimal signal transfer and minimal distortion. Traditional soldered connections can introduce distortion due to the inconsistent properties of solder. To avoid this, AudioQuest uses a high-pressure cold-weld process that creates a secure, distortion-free connection without the use of solder.

Additionally, the ground shells are stamped rather than machined, allowing the use of metals selected specifically for their low-distortion properties rather than ease of manufacturing. The gold plating further enhances performance by providing superior conductivity and resistance to corrosion, ensuring long-lasting, high-quality audio reproduction.
