From Telephone Lines to Musical Truth

George Cardas didn't come to high-end audio through music or electronics - he solved transmission problems for the telephone company. This unique perspective revolutionized cable design when he founded Cardas Audio in 1979. While others focused on exotic materials, Cardas asked fundamental questions about signal propagation that nobody else was asking.

His breakthrough? Understanding that the speed of electrical signals in conductors doesn't match the charge propagation velocity in dielectrics. This mismatch causes temporal smearing - the digital equivalent of a blurred photograph. While other manufacturers tried band-aid solutions like network boxes, Cardas solved the problem at its source with his patented Matched Propagation technology.

Today, Cardas cables are found in mastering studios, concert halls, and reference systems worldwide. The Clear series represents four decades of refinement - cables that don't add or subtract, they simply preserve.

Why Digital Cables Matter More Than Ever

• Matched Propagation Design: Conductors are deliberately slowed to match dielectric speed, eliminating time-domain smearing that destroys micro-detail
• Golden Ratio Scaling: Conductor sizes from 41 to 39 AWG follow nature's perfect proportion, minimizing resonances
• Kevlar Core Technology: Military-spec aramid fiber prevents mechanical vibration from corrupting the delicate digital signal
• 99.9999% Pure Copper: Six-nines oxygen-free copper with SPN clear coat preserves phase coherence
• Damping Strand Integration: Prevents computer clock noise from contaminating the audio signal path

What the Golden Ears Are Saying

"It's an excellent, affordable baseline cable; well-executed in Cardas' inimitable fashion, has an easy, even-handed performance that doesn't try to highlight any particular aspect. If it errs, it errs on the side of sounding bigger and more refined than many of its rivals." - Hi-Fi+ Magazine

"The Cardas 'first do no harm' rule applies here, and the Clear USB manages to deliver a fine combination of honesty and integrity to the sound, without the artificial bloom of bass-heaviness or shrill treble commonly encountered in USB audio." - Hi-Fi+ Review

What Makes Clear USB Revolutionary

Most USB cables treat digital signals as simple ones and zeros, ignoring the analog waveform that actually carries those bits. Jitter, timing errors, and noise aren't just numbers on a test bench - they translate directly to harshness, flatness, and listener fatigue.

The Clear USB's genius lies in recognizing that digital audio transmission is ultimately an analog problem. Those square waves must maintain their shape through the cable. Any rounding, overshoot, or timing variation becomes audible distortion. The Matched Propagation technology ensures the leading and trailing edges of each bit arrive simultaneously, preserving the critical timing relationships that define soundstage width, depth, and instrument placement.

This cable doesn't make your DAC sound different - it allows your DAC to sound correct. The music emerges from a blacker background with improved spatial cues and natural decay. It's the difference between looking through a window and looking through clean glass you didn't know was there.

Perfect System Matching

Ideal for: Computer audio servers to DACs, streamers requiring USB connection, recording studios using digital interfaces, systems where USB is the primary digital connection, upgrading from generic cables, revealing what your DAC is truly capable of.
