Enjoy the benefits of advanced metallurgy and design with AudioQuest"s Diamond Lightning cable with solid 100% Perfect-Surface Silver (PSS) conductors and 72-volt DBS System. Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries, which exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. Diamond USB uses air-filled Foamed-Polyethylene Insulation because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials. 100% shield coverage is easy and commonplace with cables. But preventing captured RF Interference from modulating the equipment"s ground reference requires AQ"s Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipment"s ground plane. AudioQuest"s DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check. Precision direct-silver plated pins are carefully attached with the very best solder.
