USB Cable Stage III Concepts XPHYNX USB
Description
A.S.P. Xphynx — reference USB cable with palladium conductors in a vacuum dielectric
Stage III Concepts A.S.P. Xphynx is a digital USB cable designed for the transfer of high-resolution audio between source and DAC, with its entire construction developed from the ground up around the specific demands of the USB interface. These differ from older digital links, which is why the cable's architecture deliberately suppresses jitter, timing errors and data-flow inconsistency. At its core is a combination of palladium-alloy conductors and a primary vacuum dielectric — an approach quite unlike conventional USB designs.
By its very nature, vacuum comes close to the ideal dielectric, minimising dielectric absorption and its influence on pulse timing. The electromagnetically optimised palladium conductors are complemented by highly effective multi-layer shielding and a mechanical damping system that limits the transfer of vibration and resonance into the signal path. The whole construction thus isolates the fragile digital signal from external EMI/RFI interference as well as from mechanical disturbance.
Every signal-carrying element — conductors and connectors alike — undergoes cryogenic treatment, which unifies the material structure and contributes to a more stable flow of current. The result of reduced timing deviation is more accurate sample reconstruction in the converter: clearer legibility of micro-detail, more stable instrument placement within the stereo image, and a calmer background free of digital hardness.
In keeping with the philosophy of the Stage III Concepts reference series, no mass-produced components are used in the cable — the cable is built by hand in the USA, including its proprietary connector solutions. This is a solution for top-tier systems, where the USB link is a fully fledged part of the signal path.

Stage III Concepts
The American company Stage III Concepts, founded in 1996 by the passionate audiophile and engineer Luis de la Fuente, represents the very pinnacle of the ultimate high-end cabling category. The brand has made history as the world’s first manufacturer to use pure silver ribbon conductors and air dielectric technology in its cable designs. Stage III Concepts’ philosophy rejects any form of mass production and relies exclusively on handcrafted manufacturing, proprietary patented solutions and uncompromising materials that ensure signal transmission without any electrical or mechanical distortion.
The brand’s comprehensive portfolio includes speaker, signal, power and digital cables designed for the most demanding audio systems on the planet. Stage III Concepts products utilise unique cryogenically treated monocrystalline silver conductors, advanced shielding comprising Teflon-air tubes, and solid protective sheaths filled with granules and mats that dampen micro-vibrations. The result is an extremely low noise floor, surgically precise spatial localisation, enormous dynamic headroom and sonic neutrality that allows the music to retain its full emotional impact. For listeners seeking a cable connection without any technical or acoustic compromises, Stage III Concepts cables represent the ultimate solution.
