Ultra-High Purity, Audiophile Interconnect Cable Designed by Demian Martin

Sigma Retro™ Gold: A Truly Advanced Audio Cable
A superior audio system needs superior cables to reproduce music as it was initially created. And today's most discriminating audiophiles expect nothing short of perfection in the form of tight bass, rich tonal balance, and a nearly 3D-quality soundstage. To satisfy these expectations, Monster Cable has created Sigma Retro Gold Interconnect Cables — the pinnacle of Monster's achievements in audio technology. Beautiful to the ear and eye, they deliver the ultimate performance by combining the finest materials with today's cutting-edge technologies.

Construction Without Peer
Sigma Retro Gold Interconnect Cables were crafted with a dual objective: simplicity and purity. To recreate sound as it was heard in its original environment, the designers explored the three major elements of cable construction that determine performance — the conductor, the insulators, and the geometry — to control the propagation of the entire musical signal intact as it passes through a fine audio system.

Ultra-Pure Copper Conductor. Sigma Retro Gold Interconnect Cables are carefully manufactured with 99.9999% copper, drawn to specification by custom machinery. They are then put through a special annealing process to give it the finest conductive properties while staying flexible and corrosion-resistant for the purest and most detailed midrange.

Advanced Proprietary Insulation Materials. Sigma Retro Gold's insulation materials have also been chosen with particular care. First, patented MicroFiber^® is wound around the various wire networks to provide proper isolation and protection from contact generated noise, to ensure the quietest background and the greatest freedom from cable-generated noise. Then a distinct cross-linked polymer dielectric called PEX-2^® is pressure-extruded using laser-controlled precision dies to the precise dimensions to produce the insulation, which reduces capacitance and ensures stability for a wide range of frequencies. Since PEX-2 does not chemically react with copper, it guarantees that the impeccable high frequency performance will not degrade by corrosion at the copper surface. Lastly, the Super MultiTwist™ construction rejects audio bandwidth distortions for greater clarity and imaging.

Geometry Based on Decades of Experience. To ensure overall consistency and excellence in performance, Sigma Retro Gold's patented proprietary technologies represent the best in winding methods, gauge selection, and twist design. Speaker terminations feature 24k platinum/gold contact alloy spade connectors that are flat on one side for maximum contact area and Turbine^® textured on the other side for a secure clamp to the binding post. The finished cable is covered in an elegant woven fabric reminiscent of the Golden Age of Hi-Fi during the 1950s and 60s.

Performance Synonymous with Monster Cable
With the creation of Sigma Retro Gold Interconnect Cables, Monster has combined comprehensive technological research with vast experience to capture the flavor of a classic era, when the word music was synonymous with beauty. Packed with innovative, patented technologies, Sigma Retro Gold Interconnect Cables deliver superior bottom-end definition and punch, high-frequency air and extension, nicely detailed midrange with rich tonal colors, an expansive soundstage, and solid three-dimensional images. From a dinosaur's roar to an elf's whisper to the softest cord in your favorite concerto, you'll hear every nuance of sound and music with maximum articulation and sonic accuracy.
