Coffee HDMI uses 10% silver-plated solid core conductors, but also introduces AudioQuest’s Dielectric-Bias System (DBS, US Pat #s 7,126,055 & 7,872,195 B1). DBS provides a drop in the perceived noise floor and an increase in dynamic contrast, preserving all the subtle nuances and textures of the audio signal.

Main Features:

  • Solid 10% Silver Conductors

Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated conductors are excellent for very high-frequency applications, like HDMI audio and video. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of high-purity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. This is an incredibly cost effective way of manufacturing very high-quality HDMI cables.

  • 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 (organises) the molecules of the insulation. This minimises 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.

  • Foamed-Polyethylene Insulation

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. Coffee 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.

  • High Speed Data Capacity

HDMI standards and capabilities have improved significantly since DVI first evolved into HDMI. All generations are backward compatible. However, not all previous HDMI cables can transmit the full 18Gbps of data required to optimise today’s HDMI 2.0 equipment. While there is currently no 4K/60 4:4:4 software requiring the full 18Gbps capability of HDMI 2.0, some sources (UHD Blu-ray players) can be set to upsample, requiring 18Gbps capability. (Upsampling often should be done in the TV rather than in a previous component — but that’s your decision.)

It is important to understand that all AudioQuest HDMI cables up to 8 metres are guaranteed to exceed the requirements for all possible HDMI 2.0/HDCP 2.2 data streams, including 4K UltraHD, HDR, and Blu-ray Ultra HD. In addition, AudioQuest Pearl makes use of Active Frequency-Equalisation to enable full 18Gbps/4K UltraHD performance from 10 to 15 metres.

  • Ethernet and Audio Return Channel Enabled

All AudioQuest HDMI cables up to 10 metres are rated High Speed with Ethernet. From 12 metres to 20 metres AudioQuest HDMI cables are Standard Speed with Ethernet.

  • Directionality

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.

  • HDMI Active

Active frequency-equalisation enables 18Gbps over long distances.

  • AudioQuest HDMI Technology

AudioQuest has a well-earned reputation as a manufacturer of exceptional analogue video cables. However, the advent of HDMI in 2004 presented a new set of design challenges that needed to be solved. In order for AQ to maximise audio and video performance over HDMI, new materials and higher levels of manufacturing precision were employed to handle the high-speed, high-bandwidth signals of HDMI.

While the basic blueprint for HDMI cable construction was established by the HDMI steering committee (HDMI, LLC) AQ examined areas that could be optimised within the established framework. Several of the analogue audio and video design elements that have proven so important over the years turned out to be meaningful to HDMI cable design. Solid core conductors, conductor metallurgy, insulation material (dielectric) and overall precision of manufacture have all been carefully optimised to create a superior line of HDMI cables.

As part of AudioQuest’s re-examination of HDMI cable design, specific attention was paid to maximising the sonic performance of HDMI. Indeed, AQ’s HDMI cables push the sonic performance to new levels. AudioQuest begins with Long-Grain Copper (LGC) and adds increasing amounts of silver-plating culminating in Diamond HDMI, whose 5 primary signal pairs are made using solid Perfect-Surface Silver (PSS). AQ listens to each primary signal conductor in every HDMI cable to determine proper conductor orientation. Solid Polyethylene insulation ensures stable conductor geometry while minimising insulation-induced phase distortion. On the top two HDMI cables, Coffee and Diamond, AudioQuest’s patented Dielectric-Bias System (DBS) polarises the insulation on the five primary signal pairs, providing a drop in the perceived noise floor and an increase in dynamic contrast.
