Columbia improves upon one technology and introducesanother. AudioQuest’s Noise-Dissipation System receives an additional layer, which further reduces the modulation of noise on the ground plane. Next, weintegrate Dielectric-Bias System (DBS, US Pat #s 7,126, 055 & 7,872, 195 B1). DBS reduces the loss and distortion of the audio signal, preserving the subtlenuances and textures. Your music will appear from a blacker background withgreater dimensional space. SOLID PERFECT-SURFACE COPPER+ CONDUCTORS (PSC+):Perfect-Surface Copper+ has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire’s surface at everystage of drawing and fabrication. When high-purity low-oxide copper is kept assoft, pure and smooth as possible, it becomes a wonderfully low-distortion PSC+conductor. PSC+ is manufactured by applying the same exceptional technology toan ultra-pure copper. The resulting sound quality is even more focused andsimply less in the way. For over 30 years AudioQuest has pioneered the use ofsuperior metals; yet even we were surprised by the huge leap in performancemade possible with Perfect-Surface Technology. PSC+ simply outperforms allpreviously available copper metals at any price. All of Columbia’s conductorsare solid. Electrical and magnetic interaction between strands in aconventional cable is the greatest source of distortion, often causing asomewhat dirty, harsh sound. Solid conductors are fundamental toward achievingColumbia’s very clean sound. POLYETHYLENE AIR-TUBE INSULATION: Any solid materialadjacent to a conductor is actually part of an imperfect circuit. Wireinsulation and circuit board materials all absorb energy (loss). Some of thisenergy is stored and then released as distortion. All of Columbia’s conductorsuse PE Air-Tube Insulation because air absorbs next to no energy, andPolyethylene is low-loss and has a benign distortion profile. PE Air-TubeInsulation causes much less of the out-of-focus effect common to othermaterials. 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, abig problem for very time-sensitive multi-octave audio. AudioQuest’s DBScreates a strong, stable electrostatic field which saturates and polarizes(organizes) the molecules of the insulation. This minimizes both energy storagein the insulation and the multiple nonlinear time-delays that occur. Soundappears from a surprisingly black background with unexpected detail and dynamiccontrast. The DBS battery packs will last for years. A test button and LEDallow for the occasional battery check. CARBON-BASED 3-LAYER NOISE-DISSIPATION SYSTEM (NDS): 100%shield coverage is easy. Preventing captured RF Interference from modulatingthe equipment’s ground reference requires AQ’s Noise-Dissipation System. Metaland Carbon-Loaded synthetics prevent most RFI from reaching the equipment’sground plane. TRIPLE-BALANCED GEOMETRY: The three conductors inTriple-Balanced Columbia cables ensure that whether prepared with RCA or XLRplugs, the positive and negative signals have equally low-distortion conductingpaths. The 100% coverage shield is never used as an inferior conductor. COLD-WELDED DIRECT-SILVER PLATED PURE OCC COPPER SYSTEM: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-WeldedSystem, which provides a superior connection that ensures that the structuralintegrity of the conductor is kept completely intact.   The Cold-Welded System refers to acombination of high pressure at the point of contact and the use of copper- or silver-impregnatedpaste. (Columbia’s copper conductors get copper paste. ) XLR plugs are alsoavailable. ]]>
