About this product:Soaring to New Heights of Clarity and MusicalityThe AudioQuest Wild Blue Yonder interconnects are among the worlds very best. These cables contain the finest materials: superior conductor metals, shielding scheme and connectors, and termination process. Wild Blue Yonders low inductivity and impedance offer an immensely pure, detailed, and natural sound. It is simultaneously dynamic and lush, and purely neutral. This cable is a both a work of art and a labor of love for Bill Low, AudioQuests president. In our opinion, and in terms of our recent listening tests, these high-priced cables are worth every penny. If your reference system demands the best, you need to hear AudioQuest Wild Blue Yonder!...anyone looking for unbridled quickening of the pulse with totally reliable tracking or thrilling musical experiences without any distracting smoke and mirrors is right on the money...I know of similarly excellent cables – but none better.—Lothar Brandt, AUDIOphileSolid 100% Perfect-Surface Silver Conductors (PSS)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.Hard-Cell Foam InsulationHard-Cell Foam insulation is used exclusively in most of AudioQuests video and digital audio cables. Similar to Foamed-PE, it is nitrogen injected to create air pockets. Hard foam is used because the stiffness of the material allows the conductors in the cable to maintain the same relationship with each other along the full length of the cable, thus ensuring that the characteristic impedance of the cable is consistent.100% Shield CoverageShielding always plays an important role in any cable design, but the shield on coax interconnect plays an especially important role because it functions not only as a shield but a return path as well. Because of this, AudioQuest pays special attention to the shields metal quality and the fabrication techniques as both will effect the sound and the picture.72V Dielectric-Bias System (DBS)All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuests 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.Carbon-Based 7-Layer Noise Dissipation System (NDS)100% shield coverage is easy. Preventing captured RF Interference from modulating the equipments ground reference requires AQs Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipments ground plane. SKU: UTRA1958335 Warranty: This unit comes with a 30 day Music Direct warranty.
