AudioQuest Coax Diamond

Solid conductors prevent the electrical and magnetic mutual influence of the individual strands. The high degree of purity of Perfect-Surface Silver minimizes the distortion caused by the grain boundaries existing in each metal conductor, almost completely eliminating harshness in the sound and greatly improving transparency compared to OFHC, OCC, 8N and other coppers.

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)

Achieving 100 percent shielding is easy. To prevent “trapped” radio frequency (RF) interference from affecting the device’s ground reference, the AudioQuest Noise Dissipation System (NDS) is required. Conventional shielding absorbs noise/RF energy and then directs it to component ground away; this modifies and distorts the critical ground reference area, which in turn distorts the signal. The alternating metal and carbon-containing plastic layers in the NDS “shield the screen” by absorbing and reflecting most of the noise/RF energy before it reaches the ground-connected layer.

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.
