AudioQuest Coffee Digital Coax

AudioQuest Coffee Digital Coax

The AudioQuest Coffee Digital Coax is a 6-layer carbon shielded digital interlink with DBS and uses more silver than the Carbon.

Digital Coax cables from AudioQuest are designed to minimize distortion over an extremely wide bandwidth. In many applications, the speed of digital communication is important. This is most obvious if you want to transport large files as quickly as possible, or if you want to view large HD Video files. With Coaxial Digital cables, speed is important not only to transport as much data as quickly as possible, but much more so because the time relationship within a digital stream is incredibly important to reconstruct the analog waveform that must convey to our ears all the information, the music, and the enjoyment we derive from it. Distortion in the time domain (jitter) of the signal makes the sound sound small and flat instead of three-dimensional or sharp and enveloping instead of smooth and transparent.

MASSIVE 10% SILVERED GUIDERS: Solid conductors prevent mutual interference between wires in twisted pair cables and reduce jitter. Solid silver-plated conductors are perfect for high-frequency applications. Those signals, because they have such a high frequency, transport themselves almost exclusively over the surface of the conductor. Because this surface is made of a very pure grade of silver, the performance is almost equal to that of a solid silver conductor, but is much closer to solid copper cables in terms of pricing. This is an incredibly cost-effective way to produce high-quality Digital Coax cables.

HARD-CELL FOAM INSULATION: Hard-Cell Foam insulation is used exclusively in most of AudioQuest’s video and digital audio cables. Similar to Foamed-PE, it is nitrogen injected to create air pockets. “Hard” foam is used because the stiffness of the material allows the conductors in the cable to maintain the same relationship with each other along the entire length of the cable, thus ensuring that the characteristic impedance of the cable is consistent.

100% Shielding (FILE + SILVER SPIRAL): Shielding plays an important role in any cable design, but the shielding of coax interconnects is extra important because it acts not only as a shield but also as a return path. Therefore, AudioQuest pays extra attention to the quality of the metals used and the manufacturing techniques used for shielding, as both have an effect on picture and sound quality.

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.

COOLSTON-BASED 6-LAY NOISE-DISSIPATION SYSTEM (NDS): 100% shielding is easy. Preventing captured RF disturbances from modulating equipment ground potential requires AQ's Noise-Dissipation System. Metal- and carbon-enriched plastics prevent much of the captured RFI from reaching equipment grounding.
