Audioquest Castle Rock, 6ft pair, Single Ended to Bi-Wire Spades

About this product

Castle Rock represents the culmination of Gibraltar's long-term evolution along with performance- enhancing new systems and materials. These ingredients add up to important audible improvements and more pleasurable listening!

SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS:
Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Copper+ minimizes distortion caused by grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

CARBON-BASED NOISE-DISSIPATION and CROSS-TALK-DISSIPATION SYSTEMS (INSULATION):
The negative conductors in Castle Rock are insulated with partially conductive Carbon-Loaded Polyethylene. This remarkable material damps radio-frequency garbage from being fed back into the amplifier. Castle Rock uses Nitrogen-Injected Foamed-Polyethylene Insulation on its positive conductors because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials.

DIELECTRIC-BIAS SYSTEM:
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 very time-sensitive multi-octave audio. AudioQuest's DBS creates a strong, stable electrostatic field which 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 will last for years. A test button and LED allow for the occasional battery check.

DOUBLE STAR-QUAD GEOMETRY:
The relationship between conductors defines a cable�s most basic electrical values (capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly affect the sound. The Double Star-Quad construction of Castle Rock allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel.

SPREAD-SPECTRUM TECHNOLOGY (SST):
Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid or tubular) have the fewest discontinuities, any conductor of a particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors. The different SST-determined conductor sizes used in Castle Rock allow an exceptionally clear, clean and dynamic sound.

BIWIRING:
Castle Rock is an exceptional Single-BiWire cable. When the halves are separated at the speaker end, the Double Star-Quad Geometry turns Castle Rock into a true Double-BiWire set thanks to the magnetic autonomy of each Quad-conductor section. On its own, one Star-Quad conductor group would be a little lightweight in performance as it is biased towards treble finesse. The other Star-Quad conductor group is biased toward the bass; it�s more forceful and lacking ultimate resolution. Together they form a completely optimized full-range design. When separated, the Double Star-Quad design allows Castle Rock to be a maximum-performance Double BiWire in a single cable.
