Cardas Copper

At the heart of a Cardas cable is Our Ultra-Pure Cardas Copper.

Mined in the Southwest USA and processed in the Northeast, we employ proprietary drawing and annealing techniques to create the highest quality, purest copper strands. A Single Poly-Nylon coating is applied to prevent oxidation and eliminate crosstalk between strands. The basic building blocks of a Cardas cable have been constant since day one: Our own, Ultra-Pure Copper, produced using our proprietary method. Multi-stranded Litz conductors, with strand size varying in Golden Ratio steps. Top quality dielectric materials and innovative air-tube dielectric suspension techniques. Premium connectors machined from copper & brass, plated with silver, and a flash of rhodium. Terminations performed by skilled craftsmen, using Cardas Quad Eutectic Solder and Cardas Rosin Flux Soldering Paste. These design elements were present in the original Cardas cables, like Quadlink & Hexlink, and former flagships such as Golden Cross & Golden Reference.
Our Clear cable line combines all of this with Matched Propagation Technology, the subject of George’s most recent patent (US Patent 7,674,973), which matches the propagation rate of the conductor to that of the dielectric, eliminating time-smear distortion, improving musical integrity and dynamic range.

Performance

Cardas Clear USB is a musically neutral cable and sounds the same at any usable length. Clear USB is optimized for constant transfer impedance rather than a full wave characteristic impedance.

Standard Terminations: USB A to B. Some custom terminations available. Hand terminated in Bandon, Oregon

Design/Construction

Conductors: Matched Propagation Kevlar core, ultrafine Grade 1, 99.9999% pure oxygen free copper with SPN clear coat (Litz), gauge sizes scaled to Golden Ratio proportions.
