Solid Perfect-Surface Copper+ (PSC+) Conductors
Solid conductors prevent electrical and magnetic strand-interaction. PSC+ Solid-Copper minimizes distortion caused by grain boundaries and maximizes linear RF Noise-Dissipation.

Carbon-Based 3-Layer Noise-Dissipation
It's easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. NDS's alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.

Polyethylene Air-Tube Insulation

Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. AudioQuest, however, uses Polyethylene Air-Tube Insulation on both conductors, for increased geometry stabilization and improved clarity. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Polyethylene Air-Tube Insulation, with its high air content, causes much less of the out-of-focus effect common to other materials.

Asymmetrical Double-Balanced Geometry
Purpose designed for single-ended applications, Asymmetrical Double-Balanced Geometry offers a relatively lower impedance on the ground for a richer, and more dynamic experience. While many single-ended cable designs use a single path for both the ground and the shield, Double-Balanced designs separate the two for cleaner, quieter performance.

Cold-Welded, Direct-Silver Plated Pure Purple Copper Terminations
Direct-Silver Plating is optimized for sound, using no underlying layer of distortion-causing nickel, while the highly effective cold-weld process avoids sound-degrading solder.



  • Solid Perfect-Surface Copper+ (PSC+) Conductors: Solid conductors prevent electrical and magnetic strand-interaction. Solid PSC+ Copper minimizes distortion caused by grain boundaries and maximizes linear RF Noise-Dissipation. The result is clearer, cleaner, more naturally beautiful sound.
  • Asymmetrical Double-Balanced Geometry: While many single-ended cable designs use a single path for both the ground and the shield, Double-Balanced designs separate the two, providing a relatively lower impedance on the ground for cleaner, quieter performance.
  • Carbon-Based Noise-Dissipation: AudioQuest’s Noise-Dissipation technology significantly reduces the RF Noise that reaches active circuits and causes masking effects.
  • Polyethylene Air-Tube Insulation: Because air absorbs next to no energy and Polyethylene has a benign distortion profile, Polyethylene Air-Tube Insulation, with its high air content, causes much less of the out-of-focus effect common to other materials. The result is clearer, more coherent sound.

Andrew X. ★★★★★

Ran this from my phone to an old amp in the garage and the background hiss disappeared. The solid PSC+ conductors really keep the signal clean, and bass feels tighter than the stranded cable I used before.

Robert ★★★★★

The solid copper conductors really did clean up the lower end on my desktop setup. Bass lines through my old powered monitors sound tighter, and I'm not hearing that faint grain I used to get. Connectors fit snug too, no wiggle.

Scarlett ★★★★★

Swapped out the stock cable between my DAC and amp and the noise floor dropped noticeably—backgrounds are just blacker now. The solid PSC+ conductors seem to do what they claim, since I'm picking out little reverb tails I never noticed before. Build quality feels solid too, connectors seat with a sa
