AudioQuest Big Sur RCA-RCA Cable

Big Sur
Analog-Audio Interconnect Cable named after the Bixby Creek Bridge and the majestic beauty of California's spectacular coastline at Big Sur.
In all Bridges & Falls, you will 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
Solid conductors prevent both electrical and magnetic interaction strand-to-strand interaction, major sources of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the fields within a conductor, and for the magnetic fields that extend outside the conductor. The astonishingly smooth and pure surface of all AudioQuests’s Perfect-Surface metals nearly eliminates harshness and greatly increases clarity compared to lesser materials. Extremely high-purity Perfect-Surface Copper+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
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.
METAL-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. 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. Noise-Dissipation "shields the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.

FOAMED-POLYETHYLENE 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. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.

“Our connection with the music grew stronger yet when we switched to Big Sur. Bass control, high-frequency extension, transient articulation, overall clarity, and all that good stuff were all improved, but now the musicians seemed to play with even greater purpose and intensity. We felt as if we were in a jazz club, watching rapt, following the many careful twists and turns as Cannonball Adderley, John Coltrane, and Miles took their memorable solos.” – Stereophile Magazine
