Cardas Clear Power 2m

The Cardas Clear Power power cable is the result of more than 25 years of research and development in the field of power cables. An evolution of the Golden Reference Power model, it adopts a construction aimed at a neutral tonal balance, with an integrated filtering system designed to optimize dynamic handling. Its large-gauge conductors (3 x 11.5 AWG) make it equally suitable for high-current amplifiers and sensitive source components requiring stable, clean power.

Physical design mastered down to the smallest detail

The Clear Power stands out with its 15.49 mm outer diameter, reflecting the richness of its internal structure. At the heart of the cable, three multi-strand Litz conductors in OFC copper with an exceptional purity of 99.9999% are arranged in a twisted triad, a geometry that naturally minimizes electromagnetic interference. Each 11.5 AWG conductor is made up of multiple copper strands whose diameters follow the proportions of the golden ratio, a technique patented by George Cardas that limits micro-vibrational resonance phenomena.

The thermoplastic rubber (TPR) outer jacket offers remarkable flexibility that greatly facilitates installation, even in the tightest spaces. This flexibility contrasts pleasantly with the usual rigidity of large-diameter power cables. The Cardas Power connectors, entirely handmade in the Bandon, Oregon workshops, feature solid copper blades and clips plated with a silver/rhodium combination, ensuring optimal conductivity while preventing long-term oxidation.

The double shielding, combining tinned copper and magnetic wire, creates a particularly effective barrier against electromagnetic and radio-frequency interference. This protection is complemented by a complex internal structure including polyvinyl chloride (PVC) and polyethylene (PE) air tubes, bonded with a fluorinated ethylene propylene (FEP) tape, thus creating controlled air spaces that optimize the cable’s dielectric characteristics.

Exclusive technologies in the service of musicality

The multilayer internal insulation represents a technical tour de force. PFA (perfluoroalkoxy), a material with exceptional dielectric properties, envelops the conductors in a cross-field layer geometry. This architecture, combined with PE air tubes and PTFE tape, minimizes dielectric losses while maintaining constant impedance over the entire length of the cable.

The constant quality factor (Q), achieved through geometry based on the golden ratio, ensures balanced transmission across the entire frequency spectrum. This mathematical approach to cable design, inspired by the natural proportions found in the nautilus spiral (Cardas’s iconic logo), helps avoid the resonance peaks that usually color the signal.

The Clear Power’s integrated filtering system operates passively yet particularly effectively to eliminate high-frequency noise present on the electrical grid. Unlike active filters, which can sometimes compress dynamics, this approach preserves the full available current while cleaning the signal of unwanted interference. The result is an increased background silence that reveals musical details previously masked.

Remarkable versatility in use

The Clear Power demonstrates exceptional adaptability to different types of equipment. On high-power amplifiers, its generously sized conductors guarantee unrestricted current delivery, allowing the output stages to develop their full dynamic capacity during the most demanding musical passages. Transients gain impact and definition, while the bass acquires greater authority and control.

With source components CD players, DACs, preamplifiers the Clear Power reveals its finesse and ability to preserve micro-information. The separation of instruments in the soundstage becomes more precise, voices emerge with palpable presence from the sonic background, and sibilance loses its sometimes irritating character to regain striking naturalness. This dual character, both powerful and delicate, explains why this cable is equally well suited to systems based on tube amplifiers and those using transistor electronics.

The connectors are available in all international standards, including Schuko plugs for Europe and 20-amp IEC connectors for particularly power-hungry equipment. This configuration flexibility, combined with the possibility of ordering custom lengths, makes it possible to adapt the Clear Power to the specific needs of each installation.
