We have a pair of Audioquest Oak Speaker Cables, 10ft / 3m, Terminated in Spade / Spade.
They are in great condition, with a few very minor flaws in the outer sleeves near the terminations, as shown in the photos. Terminations are in excellent condition.
These do not include original packaging.
Details from the manufacturer:
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
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.
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.
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.
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. (DBS, US Pat #s 7,126,055 & 7,872,195 B1)
