AudioQuest 65-090-13 1.5 Meters Coffee USB-A > B High-Definition Audio Cable
The AudioQuest Coffee USB-A to B High-Definition Audio Cable is designed for listeners who want a cleaner, more refined digital audio connection between a computer-based source and compatible USB-B audio components. Built with solid 10% silver conductors, silver-plated long-grain copper, and AudioQuest’s Carbon-Based Noise-Dissipation technology, this cable is engineered to help minimize noise and distortion while preserving signal integrity. A 72V Dielectric-Bias System further supports clearer, more dynamic sound by reducing the effects of insulation interaction. Whether you're connecting a laptop, desktop, music streamer, USB audio interface, or other compatible source, the Coffee USB cable is made to support high-performance digital audio systems with precision and reliability.
Features
Solid conductors minimize the harmful effects of both electrical and magnetic strand-to-strand interaction. For digital cables, whose signals are of such high frequency that they travel almost exclusively on the surface of the conductor, increasingly thick layers of silver plating are applied to AudioQuest’s Long-Grain Copper (LGC) conductors to further improve Noise-Dissipation. Placing the superior metal on the outside of the conductor produces the greatest benefit on overall performance—a superbly cost-effective way to maximize a digital cable.
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.
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.

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 minimizing distortion.
All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. For most models of AQ cable, the arrows not only indicate the direction that optimizes metal-directionality as part of Noise-Dissipation, but also indicates non-symmetrical attachment of shield and GND in order to optimize full-system performance. A fundamental aspect of AudioQuest's multifaceted Noise-Dissipation technology, Direction-Controlled Conductors ensure induced noise is dissipated and drained properly.

Frequently Asked Questions
-
The cable uses solid 10% silver conductors and silver-plated long-grain copper (LGC) conductors, which help maximize signal integrity by minimizing electrical and magnetic interference. These high-quality materials are chosen to provide cleaner and more refined digital audio connections.
-
It employs AudioQuest's Carbon-Based 3-Layer Noise-Dissipation technology, which uses alternating layers of metal and carbon-loaded synthetics to absorb and reflect radio frequency interference (RFI) before it distorts the signal. Additionally, the cable has a 72V Dielectric-Bias System (DBS) that helps maintain signal integrity by reducing phase shifts caused by the cable's insulation.
-
Hard-Cell Foam Insulation stabilizes the signal-pair geometry within the cable, reducing distortion by preventing energy absorption and release around the conductors. Its nitrogen-injected air pockets avoid energy absorption and the stiffness of the material helps maintain consistent impedance along the cable.
-
Yes, the cable features direction-controlled conductors due to the non-symmetrical grain structure of the metal strands. The direction is optimized to drain noise away from the signal path, enhancing sound quality. Arrows on the connectors indicate proper orientation for installation.
-
The cable is compatible with most computer-based audio systems including laptops, desktops, music streamers, and USB audio interfaces, facilitating high-quality digital audio connections between these sources and compatible USB-B audio components.
