Description
We are selling the Coffee USB A to B digital cable from Audioquest, in a 1.5 m or 5 ft length. This comes with Audioquest’s signature DBS system that keeps out noise, making sure you have the crispest, cleanest signal. This cable was gently used in a home studio setting, has been tested, and works great. There is no corrosion present in the battery compartment of the DBS unit, and the batteries have been removed from the DBS unit to prevent corrosion from starting. Item retails for $479.95. From a non-smoking home studio.We ship with tracking within two days of payment.We do our best to represent items accurately. Please look at the photos closely.Returns not accepted.We pack items with great care. However, as the seller, we are not liable for any products damaged or lost during shipping. If your item is damaged, please contact the shipping carrier. In 1982 Sony gave us Perfect sound forever, along with the attitude that, its just digital, so all CD players sound the same. That was disproved and qualitative differences between players became accepted truth. Next came separate transport and DAC combos, which brought with it the attitude that all S/PDIF digital audio cables sound the same... until that too became disproved. Now the frontier has moved once again. Is digital audio really just ones and zeros? We dont believe so, and once youve had a chance to listen to Coffee USB, you wont think so either…CARBON-BASED 3-LAYER NOISE-DISSIPATION SYSTEM (NDS): Its easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipments ground reference requires AQs 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. NDSs 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.DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP: 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. (DBS, US Pat #s 7,126,055 & 7,872,195 B1)HARD-CELL FOAM INSULATION: 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 cables conductors to maintain a stable relationship along the cables full length, producing a stable impedance character and further minimizing distortion.ALL CONDUCTORS CONTROLLED FOR RF NOISE DIRECTIONALITYSOLID 10% SILVER CONDUCTORS: 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.
