Audioquest Bigsur RCA Interconnect Cable

AudioQuest : Big Sur (RCA to RCA) สายสัญญาณ

Spanning
a creek and a formidable travel-impeding canyon the Bixby Creek Bridge
compliments and counterpoints the majestic beauty of Californias
spectacular coastline just north of Big Sur 190km (120 miles) south of
San Francisco. As an integral part of this stretch of landscape the
bridge has been featured in numerous TV shows and movies and is seen on
travel posters all over the world
SOLID PERFECT-SURFACE COPPER+ CONDUCTORS (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 PSC+ conductor. PSC+ is manufactured by
applying the same exceptional technology to an ultra-pure copper. The
resulting sound quality is even more focused and simply less in the way.
For over 30 years AudioQuest has pioneered the use of superior metals;
yet even we were surprised by the huge leap in performance made possible
with Perfect-Surface Technology. PSC+ simply outperforms all previously
available copper metals at any price. All of Big Surs conductors are
solid. Electrical and magnetic interaction between strands in a
conventional cable is the greatest source of distortion often causing a
somewhat dirty harsh sound. Solid conductors are fundamental toward
achieving Big Sur’s very clean sound.
FOAMED-POLYETHYLENE INSULATION:


Any solid material adjacent to a conductor is actually part of an
imperfect circuit. Wire insulation and circuit board materials all
absorb energy (loss). Some of this energy is stored and then released as
distortion. Big Sur 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. Thanks to all the air
in Foamed-PE it causes much less of the out-of-focus effect common to
other materials.
METAL-LAYER NOISE-DISSIPATION SYSTEM (NDS):


100% shield coverage is easy. Preventing captured RF Interference from
modulating the equipment’s ground reference requires AQ’s
Noise-Dissipation System. Noise-Dissipation System prevents a
significant amount of RFI from reaching the equipment’s ground plane.
DOUBLE-BALANCED ASYMMETRICAL GEOMETRY:


Purpose designed for single-ended applications Double-Balanced
Asymmetrical Geometry offers a relatively lower impedance on the ground
for a richer and more dynamic experience. While many single-ended cable
designs use a single path for both the ground and the shield
Double-Balanced designs separate the two for cleaner quieter
performance.
COLD-WELDED GOLD-PLATED PURE PURPLE-COPPER RCA PLUGS:


This plug design allows for a connection devoid of solder which is a
common source of distortion. Because the ground shells are stamped
instead of machined the metal can be chosen for low distortion instead
of machinability. Purple-Copper offers a cleaner clearer sound than the
nickel-plated or OFHC metals commonly found in competing manufacturers
plugs.
