Monster Cable Products, Inc., a leading manufacturer of high-end speaker, audio, video cables and accessories has announced the release of Sigma Retro Gold speaker and interconnect cables. Monster says that Sigma Retro Gold cables are the result of years of exhaustive research to develop the very finest cable available for music reproduction. There are a large number of companies manufacturing cables today and each one has a story of what construction techniques result in the very best sound, but according to Monster Cable, very few of these stories have a legitimate technological basis. Monster Cable, says the company, is different because the company has developed the widest variety of audiophile cables available, packed with innovative, patented technologies. With the creation of Sigma Retro cables, Monster reports that it has combined comprehensive technological research with vast experience in developing and marketing cables to capture the flavor of a classic era, when the word music was synonymous with beauty. Sigma Retro Gold cables are beautiful to the ear and eye. They deliver the ultimate performance by using the finest materials with todayís cutting-edge technology. The design reflects a vintage look reminiscent of the Golden Age of Hi-Fi during the 1950s and 60s. Sigma Retro Gold is designer Demian Martinís latest achievement in an illustrious 20-year career, distinguished by innovative designs that have defined the future direction of audio.Monster says that in designing Sigma Retro, Demian and his team had one clear objective: simplicity and purity. They used only the finest materials and the best technologies from the most successful audiophile cables ever designed.Sigma Retro Gold cable uses ultra-pure copper, drawn to specification by custom machinery. It is put through a special annealing process to give it the finest conductive properties, while staying flexible and corrosion-resistant for the purest, most detailed midrange. Proprietary insulation materials, says the company, have been chosen with particular care. Monsterís patented MicroFiberÆ is wound around the different wire networks to provide proper isolation and protection from contact generated noise. This ensures, says the company, the quietest background and the greatest freedom from cable generated ""hash"" and noise. A special cross-linked polymer dielectric, PEX-2ô, is then pressure-extruded, says the company, using laser-controlled precision dies to the optimum dimensions to create the insulation. This reduces capacitance and ensures stability from the highest to the lowest frequencies. The result, according to Monster Cable, is the ultimate listening experience. Sigma Retro Gold speaker cables come terminated w/CNC machined copper connectors with white gold alloy plating. Sigma Retro Speaker Cables range in price from $1,250 per pair to $3,000 per pair according to length. Sigma Retro Gold Interconnects range in price from $750 per pair to $1,500 per pair. The Sigma Retro Speaker/Interconnect Kit with one 8ft pair of cables and a 3ft and 6ft pair of interconnects packaged in a classic brushed silver satin briefcase retails for $4,500.For more information on Monster Cable products contact Nicole Appleblum at 415 840 2000 or visit Monsterís Web site at wwwmonstercable.com.
