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.



  • Compatible with most audio equipment with RCA connectivity: Making it easy to integrate components.
  • Air-Tube PE insulation: Minimizes contact with the cable's conductors, reducing sonic smearing, preserving dynamic contrast and ensuring faithful audio reproduction.
  • Solid Perfect-Surface Copper+ high-grade purple-copper conductors: With cold-welded terminations deliver reliable signal transfer.

Customer Reviews (4.8 / 5 · 5 reviews)

Mia T. ★★★★★

Swapped these into my phono setup and the background got noticeably quieter right away—those solid PSC+ conductors really do cut the grunge I was hearing before. Bass lines feel tighter too, nothing bloated.

Harper Z. ★★★★★

I was skeptical about solid conductors until I actually heard how much quieter the background got on my turntable. The PSC+ copper really does seem to keep the signal cleaner, no grain or harshness in the highs. Two weeks in and I'm not swapping these out.

Amelia ★★★★★

Connected my turntable to the amp with this and the noise floor dropped noticeably — quieter between tracks than the cable it replaced. The solid copper conductors seem to do what they claim, and it feels sturdy without being stiff.
