Diamond HDMI incorporates AudioQuest’s highest-performance, lowest-distortion Perfect-Surface Silver conductors. Silver is known for its high conductivity and its “colorless” sonic presentation.
Solid 100% perfecr-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.
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 HDMI 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.
Carbon-based 3-layer noise-dissipation system (NDS)
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.
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.
High speed data capacity
All AudioQuest HDMI cables up to 10 meters meet or exceed the 10.2 Gbps maximum data rate for HDMI and are approved High Speed with Ethernet cables. This means that all AudioQuest cables up to 10 meters are capable of transmitting 100% of the data required for all of HDMI’s current audio/video features including multichannel high-resolution audio, 1080p and 4k video, and 3D video from Blu-ray. All AQ HDMI cables will deliver 100% of the data required for 120Hz/240Hz/600Hz displays.
Ethernet and audio return channel enabled
All AudioQuest HDMI cables up to 10 meters are rated High Speed with Ethernet. From 12 meters to 20 meters AudioQuest HDMI cables are Standard Speed with Ethernet.
All audio cables are directional. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. All signal conductors controlled for digital-audio direction in AudioQuest HDMI cables, and care is even taken to run the conductors used in the Audio Return Channel in the opposite direction to ensure the best performance for that application. Arrows are clearly marked on the connectors to ensure superior sound quality.
