AudioQuest Wild Digital Coax Cable
The S/PDIF (Sony/Philips Digital InterFace), which arrived in 1983 along with the CD, is still very much a part of our world today. S/PDIF is transmitted through digital coax and a 75Ω cable is like a conduit that has to carry relatively low-frequency analog video (composite video, up to 4.2 MHz), or super-sensitive digital audio (S/PDIF, up to 24.576 MHz), or uncompressed High-Definition video (up to 750 MHz), or cable TV/broadband (CATV, up to 1 GHz).

Solid 100% Perfect-Surface Silver (PSS) Conductors :
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 that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
Hard-Cell Foam Insulation :
Hard-Cell Foam insulation is used exclusively in most of AudioQuest’s 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 Coverage (Copper Foil/Perfect-Surface Silver Spiral) :
Shielding 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 shield’s metal quality and the fabrication techniques as both will affect the sound and the picture.
72V Dielectric-Bias System (DBS, US Pat #s 7,126,055 & 7,872,195 B1) :
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. 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.
Carbon-Based 7-Layer Noise-Dissipation System (NDS), 2 x EMI Absorption :
100% shield coverage is easy. 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 has been the largest cable supplier to the high-end specialist market for many years. AudioQuest is sold in several hundred outlets in the US and in over sixty countries. Bill Lowe (Founder) is especially pleased that this success has been possible despite his insistence that the foundation of the company, and the foundation of AudioQuest marketing, must be the performance of the product. In the audio world, many professionals have learned that it is not always convenient to listen to the products they sell … they might learn something they don’t want to know! Bill has always understood the challenge of basing the existence of AudioQuest on the performance of the product. However, to Bill, this is the only reasonable way to do business and the only acceptable way to combine his passion for music (and all things high performance), with his need to make a living.
