| Conductors:
All four of CV-4's conductors are solid. Electrical and
magnetic interaction between strands in a conventional cable is
the single greatest source of distortion, often causing a somewhat
harsh, dirty and confused sound. Solid conductors are the most
important ingredients enabling CV-4's very clear sound. Whether
a conductor is solid or stranded, skin-effect is a prime distortion
mechanism in speaker cables. CV-4 very simply keeps this effect
out of the audio range by using conductor sizes that are below
the threshold for audible distortion.
SST (Spread Spectrum Technology):
Any single size or shape of conductor has a specific distortion
profile. Even though radially symmetrical conductors (solid round
or tubular) have the fewest discontinuities, any 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. SST has enabled CV-4
to be the biggest possible four conductor cable that avoids audible
skin-effect.
Metal: CV-4's 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 conductor. For fifteen years AudioQuest
has pioneered the use of superior metals; yet even we were surprised
by the huge leap in performance. PSC clearly outperforms previous
AQ metals that cost over ten times as much.
All drawn metal exhibits directionality, whether in hardware
store wire or in the best AQ cable. We wish we could design away
this awkwardness. Since we can't, we pay close attention to optimizing
performance by clearly marking the cables and our terminations.
Please watch for these markings when installing any audio cables.
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 effect the sound. The spiral
construction of CV-4 allows for significantly better dynamic contrast
and information intelligibility than if the same conductors were
run in parallel. The specific 4-cross geometry used in CV-4 maximizes
this advantage.
Insulation: In a low level
cable the insulating material significantly affects the cable's
performance. However, in a speaker cable the electrical effect
of insulation is almost only heard as a dry irritating sound prior
to a cable being fully "run-in" ...technically "adapting to a
charged state." The term "break-in" does not apply because taking
away the charge will slowly return the cable to its "new" condition.
The insulation's mechanical (hard vs. soft) properties make an
important difference in stranded cables. The harder the better
in order to minimize strand movement. Since solid conductors don't
need hard insulation, they can take advantage of the vibration
damping advantage of a softer insulation.
Terminations: AudioQuest offers
a wide range of high quality connectors that allow CV-4 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 a 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 spade lugs are
soft because better metal is soft, and facilitates a higher quality
connection. AQ Spades lugs are available in several sizes. AQ
Benda-Pins fit all equipment, except pieces requiring a banana
plug or BFA connector, in which case the AQ Crimp BFA/Banana provides
unprecedented performance at a fraction the cost of those not-so-good
sounding big eye-candy versions.
CV-4 Biwire Jumpers are available to use when a single CV-4
is used with a biwirable speaker. These Jumpers have 100% trade-in
value towards a second set of cable.
A combination of these major ingredients, and many more subtle
details add up to explain how even an afford able cable like CV-4
can sound so good. |
