Audioquest K2 Speaker Cables (8FT)
At the peak of AudioQuest’s Flat Rock series sits K2. Just like the
mountaintop, from this vantage point there are very few options to look up
toward. K2 combines Solid Perfect-Surface Silver Conductors with DBS and
AudioQuest’s most successful Double Star-Quad Geometry. K2 will lift the sound
of your system to near tropospheric heights.
SOLID 100% PERFECT-SURFACE SILVER (PSS) CONDUCTORS:
Solid conductors prevent strand interaction, a major source of cable distortion.
Extremely high-purity Perfect-Surface Silver minimizes distortion caused by
grain boundaries that exist within any metal conductor, eliminating harshness
and greatly increasing clarity compared to all other conducting materials.
CARBON-BASED NOISE-DISSIPATION (INSULATION):
The negative conductors in K2 are insulated with partially conductive
Carbon-Loaded Polyethylene. This remarkable material damps radio-frequency
garbage from being fed back into the amplifier. The sonic benefit is exactly the
same reduction in “hash” and better dimensionality that comes whenever RF
garbage is reduced in an audio circuit. K2 uses 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
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, 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
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 K2
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 K2 allow an exceptionally clear, clean
and dynamic sound.
K2 is an exceptional Single-BiWire cable. When the halves are separated at the
speaker end, the Double Star-Quad Geometry turns K2 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 K2 to be a maximum-performance Double BiWire in a single
AudioQuest offers a wide range of high-quality connectors that allow K2 to be
securely attached to any type of equipment. Quality is in the low-distortion
sound, not necessarily in the eye-candy effect. AQ ends are either dull looking
gold or silver because these metals are plated directly over the connector.
There is no shiny and harsh sounding nickel layer underneath. AQ PK-spade lugs
are soft because better metal is soft, and facilitates a higher quality
connection. For pieces requiring a banana plug or BFA connector the AQ PK-BFA/Banana
provides unprecedented performance over conventional brass versions.
The metal breakouts on either end of K2 are marked “Speaker End” or “Amp End.”
