Cardas Audio Clear Beyond XL Power Cable - 4.0 Meter - 20 Amp

What You Need to Know

What Is This Cable and What Does It Do?

This is an aftermarket power cable. It replaces the cord that came in the box with your gear. Its job is to send clean, steady AC power from your wall outlet to your audio component.

Clear Beyond is one of the top two power cables Cardas makes. Only Clear Beyond XL sits above it. The Cardas line goes Iridium, Parsec, Clear Cygnus, Clear Reflection, Clear, Clear Beyond, and Clear Beyond XL.

What's Different About This One?

Clear Beyond is hand-built in Bandon, Oregon. George Cardas started the company in 1987. He used to work as a phone-line engineer. He holds three U.S. patents on cable design. His daughter Angela runs the company today.

Clear Beyond uses three 10-gauge tin-plated copper wires. AWG means American Wire Gauge. A lower number means a thicker wire. 10 AWG is heavier than the 11.5 AWG used in Clear and Clear Reflection. Heavier wire carries more power without strain. This matters for high-current amps.

The wires are pure 99.9999% Cardas copper. Cardas makes its own copper. They draw the wire slowly in a special hydrogen atmosphere. This keeps the copper very pure. Other top audio brands use this same copper. So do science labs around the world.

Clear Beyond uses Cardas Matched Propagation. This is a patented method (US Patent 7,674,973). Cardas mixes strand sizes inside each wire. This lowers internal noise. The strand sizes follow the Golden Ratio (1:1.618). Both ideas come from George Cardas's patents.

Each of the three wires gets its own shield. Then there's a second shield around all three. That's more shielding than the cables below it in the line. A toroidal filter sits on the ground leg to block more noise from the wall.

Clear Beyond uses Cardas's own E-5 connectors. They're solid copper plated with silver, then rhodium. The shells are metal with anti-resonant inner shells. A small filter ring sits at the IEC end for extra noise rejection.

Where Does This Cable Belong in Your System?

Clear Beyond is built for reference-level systems. Use it on the gear that matters most.

• Good fit: High-current power amps, monoblocks, large integrated amps, top-tier DACs, streamers, preamps, and reference source gear. Works on any component with a C13 inlet.
• Need 20-amp? If your amp uses a 20-amp inlet (the wider, sideways slot), see the Cardas Clear Beyond Power C19 version on its own page.
• Top of the line: For the most power-hungry amps, step up to Clear Beyond XL.

Length: Use the shortest cable that will reach. Measure the real path the cable will take, not a straight line. Add a foot of slack. Shorter is better.

Hand-Built and Backed for Life

Every Clear Beyond is built by hand in Bandon, Oregon. It comes with a Cardas lifetime warranty. Cardas can also re-end the cable if your system changes. They can swap connectors (such as C13 to C19) or change the length. Call us at 800-942-0220 for current re-termination pricing.

Features & Specifications

Three 10 AWG Conductors — Heavier than the 11.5 AWG wires in Clear and Clear Reflection. Built for the high-current loads of large power amps and monoblocks.

Tin-Plated Cardas Grade 1 Ultra Pure Copper — 99.9999% oxygen-free copper with tin plating. The plating slows tarnish and helps long-term stability.

Matched Propagation Conductors — Cardas patented method (US Patent 7,674,973) that mixes strand sizes to lower internal noise.

Litz Construction with Golden Ratio Strands — Many fine insulated strands per wire, sized to the Golden Ratio. A patented Cardas method.

Individual Shielding Per Leg Plus Overall Shielding — Each of the three wires gets its own shield. Then a second shield wraps all three. That's more shielding than any other Cardas cable except Clear Beyond XL.

Toroidal Filter on Ground Leg — A filter sits on the ground wire to block more noise from the wall before it reaches your gear.

PTFE Dielectric with PVC Air Tubes and FEP Tape — PTFE is the same plastic family as Teflon. Air tubes lift the wires apart for clean signal transfer.

Cardas E-5 Connectors — Pure copper plated with silver, then rhodium. Metal shells with anti-resonant inner shells. Includes Cardas's filter ring at the IEC end. The signature Cardas Nautilus logo is embossed on the shell.

Hand-Terminated in Bandon, Oregon — Every cable is built and tested at the Cardas factory.

Super-Flexible TPR Jacket — Soft deep-blue jacket. Stays manageable behind a rack despite the heavy wires inside.
