Founded by George Cardas in 1987, Cardas Audio produces high performance audio cables, premium connectors, the world famous Quad Eutectic Solder, and the finest ultra-pure Copper and Silver strand available. 


George started the company to perfect audio cables using ultra-pure materials, innovative Golden Ratio resonance control techniques, and uniquely insightful solutions to transmission line problems. The legendary connections and craftsmanship at Cardas reflect George's pursuit of perfection.


The company began in Southern California. In 1992, Cardas Audio moved to Bandon, a small town on the southern Oregon coast. While George remains our head product designer, the company is now run by Angela, his youngest daughter. 


Cardas Audio serves musicians, music lovers, recording studios, and the rest of the high-end audio industry. Our cables are found on some of the finest sounding audio systems, and our wire & connectors are used in world class speakers and electronic components. Our copper & silver wire is even used by other cable manufacturers.

Cardas Cables are arranged into product lines, each of which contains a variety of cables designed to perform at a similar level. For example, the Parsec product line contains an interconnect, speaker, power, digital, and headphone cable.

Of course, you can mix & match, as all of our product lines play well together. For example system can use Parsec speaker cables, Clear Sky interconnects, and Clear Reflection power cables. Cardas cables also work well in systems that include cables from other manufacturers.

Cardas cables feature our own Grade 1, Ultra Pure Copper wire, produced using a proprietary method developed by George Cardas prior to founding Cardas Audio.

No other method of producing copper wire results in the purity and uniform grain structure. For this reason, our copper is used by many other manufacturers, and even in laboratories around the world for it superior electrical and thermal conductivity.

We also produce high purity silver wire. Although we don't use silver in our cables, it is used by many other cable and electronics manufacturers.

Cardas Ultra Pure Grade 1 Copper
Conductor multi stranded conductor cross section

Cardas Audio uses Golden Ratio scaled, multi-stranded Litz conductors in all of our cables.

The Golden Ratio (1:1618) is found in nature, music, and often used in architecture. Some of the best sounding listening rooms employ Golden Ratio dimensions. Physical dimensions that adhere to this ratio are asthetically pleasing. Rooms built to it eliminate resonances that take away from the listening experience.

In a cable, Golden Ratio scaling involves placing the smallest wire at the center of the conductor, with each subsequent layer stepping up in size at a ratio of 1:1.618. This micro-resonance control technique is the subject of one of George Cardas' first patents, US Patent 4,628,151.

Litz conductors use multiple strands of wire, each enameled to prevent crosstalk between strands. The enamel coating also prevents the copper wire from oxidizing.

Cardas Clear Interconnect 3D render

All of the cables in our Clear product line feature Matched Propagation Conductors, as described in George Cardas's US Patent 7,674,973. Matched Propagation Conductors offer unprecedented neutrality and clarity.

Cardas Audio terminator Shayla

Terminating is the technical (and cool) term for putting a connector onto a cable.


The Cardas Terminators are the dedicated and talented group of technicians responsible for terminating cables at our factory in Bandon, Oregon. Their quality work ensures that we're able to offer a lifetime warranty on our cables.

Working with Litz wire requires special skill and tools. Click here to see our video series, "Soldering With Jesus", featuring head terminator and shop manager Jesus Ornelas.

Cardas Connectors are found on our own cables, as well as cables made by other manufacturers, and on some of the finest speakers and electronic components in our industry.

Our connectors are machined from copper or brass billet, and plated with silver, and a flash of rhodium. This plating method not only creates beautiful looking parts, but it also ensures excellent conductivity, with no fears of oxidation.


Cardas bulk cable & chassis wires are used throughout high-end audio, as well as by DIY cable & component makers. All feature our Grade 1 Ultra Pure Copper, arranged in Golden Ratio scaled, multi-stranded Litz conductors.

Cardas connectors & wire are available to DIY enthusiasts through any Cardas dealer. Manufacturers purchasing in quantity can deal directly through Cardas Audio.

Cardas Quad Eutectic Solder

Cardas Quad Eutectic Solder is a proprietary blend of copper, silver, tin, and lead. Quad Eutectic Solder is used by the Cardas Terminators, and is widely regarded as the finest solder in our industry, and beyond.


The four elements in Quad Eutectic Solder are in specific proportion to melt and solidify at a temperature lower than that of any of the component metals! Thus the resultant joint is contiguous from wire to connector rather than slurry - this provides a perfect and permanent connection that will never breakdown over time.


Quad Eutectic outperforms high-silver-content solder in ease of use, reliability of connection, and audio performance. In fact, we developed it when it was apparent that high-silver-content solder was producing less than ideal results.
