AudioQuest Oak BiWire speaker cable 8'

Gorgeous pair of Auqioquest Oak speaker cables 8' length - biwire cofiguration can be used with either biwire or standard speaker posts. Spade terminations work with virtually all speakers including Vandersteens.

These were purchased directly from Audioquest and are in excellent condition with barely a flaw upon close inspection. See photos.

Buyer pays actual shipping and PayPal fees. Local pickup and auditioning is welcomed in beautiful Walnut Creek, CA, a short drive from the Bay Area and Sacramento.

SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS
Solid conductors prevent both electrical and magnetic interaction strand-to-strand interaction, major sources of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the fields within a conductor, and for the magnetic fields that extend outside the conductor. The astonishingly smooth and pure surface of all AudioQuests’s Perfect-Surface metals nearly eliminates harshness and greatly increases clarity compared to lesser materials. Extremely high-purity Perfect-Surface Copper+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

MULTI-LAYER CARBON-BASED NOISE- AND CROSSTALK-DISSIPATION SYSTEM
This cable's negative conductors are covered with partially conductive Carbon-Loaded Polyethylene. This remarkable material reduces radio-frequency garbage being fed back into the amplifier. The sonic benefit is exactly the same reduction in "hash" and improved dimensionality that comes whenever RF interference is reduced in an audio circuit. In addition, a carbon layer damps interaction between positive and negative conductors, and an external Carbon-Based NDS System reduces external interference.

DOUBLE COUNTER-SPIRAL GEOMETRY
All AQ "Tree" Series cables have an inner circular array of positive conductors spiraling in one direction, around which the negative conductors spiral in the opposite direction. This makes possible the significant performance advantage of having the positive and negative conductors cross each other instead of being parallel. The critical need for positive and negative to have a fixed non-changing relationship is ensured as the negative and positive groups are in fact two tubes with a perfectly consistent relationship. The result is an astonishing clarity, like focusing a camera lens you had no idea was so far out of focus.

FOAMED-POLYETHYLENE INSULATION (FOR ALL POSITIVE CONDUCTORS)
FOAMED-POLYETHYLENE INSULATION (FOR ALL POSITIVE CONDUCTORS)
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Tower, however, uses air-filled Foamed-Polyethylene Insulation on both conductors. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.

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.
