Power Cable Stage III Concepts LEVIATHAN
Description
Reference-class AC power cable with 3-in-1 architecture and silver-palladium ribbon conductors
The Stage III Concepts A.S.P. Leviathan is a reference-class AC power cable conceived as a current interface for the most powerful amplifiers and demanding audio components. At its core lies a 3-in-1 architecture formed by three entirely separate multi-conductor cables that together handle a current load of up to 80 A. The construction is based on "floating" ribbon conductor technology, which the brand was the first to apply to power applications and has been refining for nearly two decades.
The conductive array consists of ribbon conductors made from a silver-palladium alloy, positioned so as to minimise mechanical contact with the surrounding layers. Immunity to interference is handled by a combination of multi-layer proprietary shielding and a specific conductor geometry, complemented by extreme mechanical damping. This combination suppresses both microphony arising from vibration and the influence of airborne electromagnetic interference.
In transmission terms, this means a low-impedance, current-unrestricted path to the components' power supplies. The result is an exceptionally low noise floor, dynamic headroom free of compression in loud passages and a calm authority of presentation that comes to the fore above all with power amplifiers that place high current demands on the mains. Eliminating current throttling contributes to better legibility of detail and more stable localisation of instruments within the soundstage.
The cable is built entirely by hand, without commercially available or off-the-shelf components — every element is the manufacturer's own design. The Leviathan thus represents the pinnacle of the Stage III Concepts power cable family, building on the A.S.P. Kraken model and multiplying its solution in a triple configuration.

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.
