    • Dielectric-Bias System 
    • Directionality 
    • High Speed Data Capacity

    The Coffee HDMI from AudioQuest uses 10% silver-plated solid core conductors, but also introduces AudioQuest’s Dielectric-Bias System. 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.

    All AudioQuest HDMI cables up to 8 meters meet or exceed the 18 Gbps maximum data rate for HDMI and are approved High Speed with Ethernet cables. This means that all AudioQuest cables up to 8 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.

    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.

    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.

    Carbon-Based 3-Layer Noise-Dissipation System

    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

    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.

    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.

    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 optimize 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. The most important thing to know and understand is that all AudioQuest HDMI cables up to 8 meters 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. 

    *Headphones.com is very pleased to announce that you have even more options to pay for your AudioQuest HDMI cables! Now when you hit the Pay with Crypto button, you have the option to pay with currencies such as NANO, Bitcoin, Litecoin, Ethereum and more! We are very excited to able to give you these options now and for the future!*
