Perfect-Surface-Copper+ has a surprisingly smooth and clean surface. Proprietary metal processing technology protects the surface of the wire at every step of drawing and manufacturing. When high-purity, low-oxygen copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor.

PSC+ is manufactured using the same exceptional technology as ultra-pure copper, resulting in a sound quality that is even more focused and unobtrusive. AudioQuest has been a pioneer in the use of high-quality metals for over 30 years, but even we were surprised by the huge leap in performance made possible by Perfect Surface technology. PSC+ outperforms all copper metals available to date at any price point. All conductors in Yukon are solid. The mutual electrical and magnetic influence of the strands in conventional cable construction is the greatest source of interference and often causes an 'impure', 'harsh' sound. Solid conductors are the fundamental basis for Yukon's pure sound.

Any solid material adjacent to a conductor becomes part of an incomplete electrical network. Wire insulation and circuit board material absorb energy (losses). Some of this energy is stored and then released as distortion. In the Yukon, PE air tube insulation is used for all conductors because air absorbs almost no energy and polyethylene has low losses and a benign distortion profile. PE air tube insulation causes significantly less blurring than other materials.

Achieving 100% shielding is easy. To prevent 'captured' RF interference from affecting the device's ground reference, the AQ Noise Dissipation System is required. Metal and carbon-containing plastics prevent most RF interference from reaching the device's ground plane.

The three conductors in Yukon 'Triple Balanced' cables, whether terminated with RCA or XLR connectors, ensure that positive and negative signals have equal, low-distortion paths. The 100% shielding is never used as an inferior conductor.

This connector design allows the connection to be made without solder, a common source of interference. Because the ferrules are stamped rather than machined, the metal can be selected for low distortion rather than machinability. Purple Copper offers a purer, clearer sound than nickel-plated or OFHC metals often found in competitor connectors. Direct silver plating is another important step toward greater clarity without compromising the signal.
