Audioquest Digital cables are designed to minimise distortion across an extremely wide bandwidth. For many applications, the speed of digital communication is important. Most visibly, “speed” is about transferring large files as quickly as possible, or carrying enough data for HD audio.
AES/EBU, developed jointly by the Audio Engineering Society and the European Broadcast Union, established a two-channel digital standard for interconnecting digital devices in the professional world. But, AES/EBU also has its application in the domestic environment as well. While AES/EBU can be single-ended, balanced, or optical, here we refer to the balanced-digital interconnect version.
The Audioquest Diamond AES/EBU cable features 100% Silver Conductors and cold-welded, hanging silver directly over pure red copper connectors.
CARBON-BASED 7-LAYER NOISE-DISSIPATION
It’s easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical “reference” ground plane, which in turn causes a distortion of the signal. NDS’s alternating layers of metal and carbon-loaded synthetics “shield the shield,” absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP
All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio-frequency noise will not be induced into the signal conductors from the DBS field elements.
SOLID PERFECT SILVER CONDUCTORS
Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest’s highest-quality metal. 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.
COLD-WELDED, HANGING-SILVER DIRECTLY OVER PURE PURPLE COPPER TERMINATIONS
This plug design allows for a connection devoid of solder, which can be a common source of distortion. Instead of solder, the process employs a high-pressure technique often referred to as cold welding. Because the ground shells are stamped instead of machined, the metal used can be chosen for low distortion instead of machinability.
HARD-CELL FOAM INSULATION
Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Hard-Cell Foam Insulation is similar to the Foamed-PE used in our more affordable Bridges & Falls cables, and is nitrogen-injected to create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release any energy from or into the conductor, distortion is reduced. In addition, the stiffness of the material allows the cable’s conductors to maintain a stable relationship along the cable’s full length, producing a stable impedance character and further minimising distortion.
