The Yosemite Valley in California’s Sierra Nevada Mountains is world famous for its beauty, for naturalist John Muir’s work to preserve the Valley, and for Ansel Adams astonishing black & white photographs (“Yosemite and the Range of Light”). Like other glacier-carved fjord-type valleys, such as the famous fjords of Western Norway, the Yosemite Valley is graced with gorgeous waterfalls along both sides. Giant Sequoia trees, the largest trees in the world, further enhance Yosemite as possibly the most beautiful of all US National Parks.

SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS: Perfect-Surface Copper+ has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire’s surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor. PSC+ is manufactured by applying the same exceptional technology to an ultra-pure copper. The resulting sound quality is even more focused and simply less in the way. For over 30 years AudioQuest has pioneered the use of superior metals; yet even we were surprised by the huge leap in performance made possible with Perfect-Surface Technology. PSC+ simply outperforms all previously available copper metals at any price. All of Yosemite’s conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the greatest source of distortion, often causing a somewhat dirty, harsh sound. Solid conductors are fundamental toward achieving Yosemite’s very clean sound.

FEP AIR-TUBE INSULATION (FEP is a Fluoro-Polymer): Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then later released as distortion. All of Yosemite’s conductors use Air-Tube insulation because air absorbs next to no energy, and FEP is the best extrudable solid insulation and absorbs less energy than other materials. The FEP Air-Tubes used in Yosemite have almost nothing but air around the solid PSC+ conductors.

DIELECTRIC-BIAS SYSTEM (DBS, US Pat #s 7,126,055 & 7,872,195 B1): All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuest’s DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.

CARBON-BASED 3-LAYER NOISE-DISSIPATION SYSTEM (NDS): 100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipment’s ground plane.

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 RED COPPER RCA PLUGS: This plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion instead of machinability. Red Copper offers a cleaner, clearer sound over nickel-plated or OFHC metals commonly found in competing manufacturers’ plugs. Direct-Silver Plating offers one more important step toward greater clarity and doing no harm to the signal.


The pioneering cable designer and manufacturer AudioQuest has been the largest cable supplier to the high-end specialist market for many years. Created in 1980 by Bill Low, AudioQuest is focused on the design and development of cables and is well known for the use of multiple connectors in their range of speaker cables. These high-end cables have been built using Bill’s understanding of the mechanisms that cause distortion in cable and have used technology to create superior sounding cables. 

AudioQuest has always based its products on performance and sound quality and have taken the design and development of cables and turned it into an art form. Over the years the range of cables has evolved from audio only to data cables, video and digital cables. These cables have been built from the ground up based on the same low distortion principles as the original audio cables. 

The results are truly superb with cables that are able to elevate a sound system by reducing distortion and providing a much clearer, harmonious and expressive tone. AudioQuest is sold in over sixty countries worldwide and is the cable of choice for professionals and enthusiasts alike.
