AudioQuest Colorado 1M

Ive Scaled back my digital front end and system in general (went from 4 mono separates to SET integrated/high efficiency). I still use the Colorados (prefer them to Sky) however the change has left me with extra cables. These cables show the usual signs of wear that one would expect from careful use. Here is a little info from the web:

AudioQuest Colorado Interconnects: Hear the Added Sonic Detail, Dynamics, Transparency, and Body From Today's Cutting-Edge Analog and Digital Sources

As significant advances in both the analog and digital realms continue to bring more detail, transparency, dynamics, and body to music playback, the importance of placing high-resolution interconnects like AudioQuest Coloradoin your system cannot be overstated. What was once considered by some serious listeners to be a luxury is now an indispensable part of experiencing soulful, emotional, lifelike, cannot-leave-your-seat sound. Akin to the western state from which it takes it name, the Golden Ear Award-winning Colorado is gorgeous, constructed to the highest-possible standards and possessing an array of patented technologies responsible for its seemingly effortless, indisputably neutral performance.

AudioQuest's Noise-Dissipation System provides shielding that practically eliminates airborne noise that leads to three-dimensional spaciousness, imaging, and soundstaging. FEP Air-Tube insulation defeats distortion and allows for reference-level timing, speed, cohesiveness, and energy. Colorado's triple-patented Dielectric-Bias System allows music to emerge with the colorful detail and dynamics displayed by pointillist masterpieces hanging in the Art Institute of Chicago. Indeed, hearing music through the ultra-transparent and non-impeding Colorado will make all your records and files appear museum-quality-worthy. Experience what audiophile sound really means in 2015 with Colorado. At these special prices, you can't afford not to act. 100% Music Direct Guaranteed.

"The Colorado offers substantially greater low-level definition and clarity. The core of this improvement lies in added detail at all levels, revealing very-low-level musical sounds. This new generation does, however, provide a level of musically natural detail that is truly exceptional. I'm using them as one of my key references."
– Anthony Cordesman, The Absolute Sound

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 every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure, and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor. PSC+ is manufactured by applying the same exceptional technology to ultra-pure copper. The resulting sound quality is more focused and simply less in the way. PSC+ simply outperforms all previously available copper metals at any price. All of Colorado's conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the greatest source of distortion, often causing a somewhat dirty, harsh sound. Solid conductors are fundamental toward achieving Colorado's very clean sound.

FEP (Fluoro-Polymer) Air-Tube Insulation
Any solid material adjacent to a conductor is part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and later released as distortion. All of Colorado's conductors use Air-Tube insulation simply because air absorbs infinitesimal energy. FEP is the best extrudable solid insulation and absorbs less energy than other materials. FEP Air-Tubes used in Colorado have almost nothing but air around the solid PSC+ conductors.

Dielectric-Bias System (DBS)
All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for time-sensitive multi-octave audio. AudioQuest's DBS creates a strong, stable electrostatic field that saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs lasts for years. A test button and LED allow for the occasional battery check.

Carbon-Based 3-Layer Noise-Dissipation System (NDS)
Preventing captured RF interference from modulating the equipment's ground reference requires AQ's Noise-Dissipation System. Metal and carbon-loaded synthetics prevent most RFI from reaching the equipment's ground plane.

Triple-Balanced Geometry
The three conductors in "triple-balanced" Colorado cables ensure that whether prepared with RCA or XLR plugs, the positive and negative signals have equally low-distortion conducting paths.

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-Welded System, which provides a superior connection that ensures that the structural integrity of the conductor remains completely intact. The Cold-Welded System refers to a combination of high pressure at the point of contact and use of copper-impregnated paste.
