Analog-Audio Interconnect Cable named after the Sydney Harbour Bridge, which is the tallest and widest steel-arch bridge in the world, and the fifth longest.

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.

Note: All cables in our Bridges & Falls Series place their left and right channels in a single jacket, and feature our Asymmetrical Double-Balanced geometry with separate high-quality positive and negative conductors. This design allows for a thin, flexible, and uniquely versatile high-performance cable that can be terminated with a variety of today’s connections, including 3.5mm (male or female), DIN, and RCA. Do keep in mind, however, that, by necessity, the plugs on Bridges & Falls cables are fairly close together. If the L and R inputs of your components are more than 3″ (7.6cm) apart, please consider models from our Rivers or Elements Series.

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.

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.

CARBON-BASED 3-LAYER NOISE-DISSIPATION SYSTEM (NDS)
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.

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.
