AudioQuest USB AB Coffee<\/strong><\/span><\/h3>\n

In 1982, Sony gave us \u201cperfect sound every time,\u201d along with the attitude that \u201call CD players sound the same because digital is digital.\u201d This has been refuted and differences in quality between CD players have been accepted as fact. Next came separate transport and DAC combos under the premise of \u201call S\/PDIF digital audio cables sound the same\u201d\u2026 until that too was disproved. Now the border has shifted again. Is digital audio really just 1s and 0s? We don’t believe that, and once you’ve had the chance to hear the Forest USB, you won’t believe it either.<\/span><\/p>\n

THREE-LAYER CARBON-BASED NOISE DISSIPATION SYSTEM (NDS).<\/span><\/strong><\/h5>\n
Achieving 100 percent shielding is easy. To prevent \u201ctrapped\u201d radio frequency (RF) interference from affecting the device\u2019s ground reference, the AQ Noise Dissipation System (NDS) is required. Conventional shielding absorbs noise\/RF energy and then dissipates it to component ground; this modifies and distorts the critical ground reference area, which in turn distorts the signal. The NDS \u201cshields the shield\u201d by absorbing and reflecting most of the noise\/RF energy before it reaches the ground-connected layer.<\/span><\/div>\n<\/div>\n<\/div>\n

DIELECTRIC BIAS SYSTEM WITH HIGH FREQUENCY NOISE TRAP<\/span><\/strong><\/h5>\n
The insulation between two or more conductors is a dielectric whose properties affect the integrity of the signal. If the dielectric is not biased, the dielectric’s involvement (absorption and nonlinear release of energy) causes different time delays (phase shift) for different frequencies and energy levels, which is a major problem for very time-critical multi-octave audio. The inclusion of an RF trap (originally developed for the AudioQuest Niagara Series power products) ensures that no high frequency noise from the DBS field elements enters the signal conductors. (DBS, US Patent Numbers 7,126,055 & 7,872,195 B1)<\/span><\/div>\n<\/div>\n<\/div>\n

HARD CELL FOAM INSULATION<\/span><\/strong><\/h5>\n
Hard-cell foam (HCF) maintains the critical conductor geometry. Any solid material adjacent to a conductor becomes part of an incomplete electrical network. Cable insulation and circuit board material absorb energy. Some of this energy is stored and then released as distortion. Hard cell foam insulation behaves similarly to the PE foam used in cheaper Bridges & Falls cables and contains nitrogen injections that create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release energy from or into the conductor, distortion is reduced. Additionally, the rigidity of the material ensures that the cable conductors do not change position relative to each other over the entire cable length, creating a stable impedance character and further reducing distortion.<\/span><\/div>\n<\/div>\n<\/div>\n

SOLID CONDUCTORS WITH 10% SILVER CONTENT<\/span><\/strong><\/h5>\n
Solid conductors prevent distortion caused by strand interaction and reduce jitter. Solid, silver-plated conductors are ideal for high-frequency digital audio and video applications. During transmission, these high-frequency signals move almost exclusively on the surface of the conductor. Since this is made of high purity silver, the reproduction is very close to that of a solid silver cable, while the price is closer to that of a solid copper cable. This is a surprisingly cost-effective way to produce very high quality digital cables.<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
