Audio cable (2 × RCA - 2 × RCA) with PSC+ copper conductors and NDS system

Towering over a majestic canyon spanning 190 miles south of San Francisco, the Bixby Creek Bridge is an essential part of the stunning California coastline. It can be seen on many posters and postcards around the world, and has been immortalized many times in a variety of TV shows and movies.

Big Sur is the ideal audio cable(2×RCA - 2×RCA). Audioquest has chosen solid copper wires with a perfect surface(PSC+) for its production, this material has an unprecedentedly fine and clean surface. Audioquest' s proprietary technology protects the surface of the material at all stages of production. By keeping the high purity oxygen-free copper soft, clean and smooth, it becomes an excellent low-loss PSC+ conductor during the process. The resulting sound is then much more focused on fidelity and clarity than when using conventional materials. For over 30 years Audioquest has been making advances in the use of select materials, yet the leap in quality made possible by PSC+ has been astoundingPSC+ technology simply offers incomparably better results compared to commercially available copper at any price point.

TECHNOLOGY

All Big Sur cable conductors are solid with a rigid core. The electrical-magnetic interactions between the fibers are the biggest source of distortion in conventional cables, resulting in an unclean, harsh sound. Solid conductors are essential on the road to achieving a perfectly clear sound.

Polyethylene foam insulation: any solid material near the conductor actually becomes part of the imperfect circuit. Cable insulation and circuit boards absorb energy and cause losses. Big Sur uses air-filled polyethylene foam for wire insulation (air absorbs almost no energy and polyethylene is low loss). Sound distortion is then absolutely minimal.

Metal layer for shielding and dispersion of external influences: or NDS system, perfectly shields the interference transmitted to the ground of the instruments and thus prevents any adverse influence on the sound.

Double-balanced asymmetrical geometry: specifically designed for single-ended applications, the double-balancedasymmetrical geometry provides relatively lower impedance for richer, more dynamic listening. While many single-ended cables use a single path for both grounding and shielding, the double-balanced design separates the two paths for much better performance.

Cold-welded, gold-plated RCA terminations made of purple copper: this solution does not involve solder, which is often a source of significant distortion. Because the connector bodies are molded, not machined, a metal that minimally affects the signal can be selected for manufacture instead of a metal that is easily machined. The use of purple copper then enhances the clarity of the sound even further.
