AudioQuest Yosemite Interconnect Cable

Analog-Audio Interconnect Cable is named after Yosemite Valley in California's Sierra Nevada Mountains. In all Bridges & Falls, you’ll find better metals and more sophisticated technologies — including Air-Tube insulation, Dielectric-Bias System, and Noise-Dissipation System — at lower prices than ever before.

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+ 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. 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 that saturates and polarizes (organizes) the molecules of the insulation. This minimizes energy storage in the insulation and the multiple nonlinear time-delays. 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:

Purposely 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, a common distortion source. 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.
