Picked these up. Very impressed in every way. Packaging, substantial cable, connectors all top quality. The sound impressive nice throat of bass down low, fantastic separation and detail. Here is the blurb. Now I come from double helix Chaperone 3, a no slouch interconnect. Now direct a/b is not possible but am I pleased with what I hear, very much. It feels more impressive although why is more difficult to explain. I’d recommend fire when budget is not a consideration, an extremely well put together cable.
SOLID PERFECT-SURFACE SILVER (PSS) CONDUCTORS
Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest's highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
FEP AIR-TUBE INSULATION (FEP IS A FLUORO-POLYMER)
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then later released as distortion. Air, however, absorbs next to no energy, and FEP is the best extrudable solid insulation, absorbing less energy than other materials. The use of FEP Air-Tube insulation, with almost nothing but air around the solid PSC+ conductors, improves the sound of an audio system's focus and dynamics.
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.

TRIPLE-BALANCED GEOMETRY (SEPARATE GROUND-REFERENCE CONDUCTOR)
Our Triple-Balanced Geometry uses a separate ground-reference conductor, so the cable's shield is never used as an inferior conductor. Whether prepared with RCA or XLR plugs, the cable's three conductors ensure that the positive and negative signals have equally superior, low-distortion conducting paths.
CARBON-BASED 8-LAYER NOISE-DISSIPATION SYSTEM (NDS)
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.
WEL-TYPE DOUBLE-CONTACT COLD-WELDED REUSABLE PLUGS, HANGING-SILVER PLATING DIRECTLY OVER MACHINED SOLID EXTREME-PURITY RED COPPER
This plug design enables a perfect heat-free connection between cable and plug. The connection between the plug and conductors is made using AQ’s Cold-Welded System, which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Welded System refers to a combination of high pressure at the point of contact and the use of copper- or silver-impregnated paste. (Wild Blue Yonder’s silver conductors get silver paste.) XLR plugs are also available.
