Strømkablet til dig som ønsker det optimale. Shunyata Sigma V2 NR er strømkablet som får det bedste ud af dine CD-afspiller, DAC, tuner, forforstærker, men gør det
desuden fantastisk som strømkabel til power conditioners.
Shunyata Research’s new Reference NR Line power cords were developed using the
same materials science and technologies that make the Omega QR the market’s
ultimate cost-no-object power cord. The Reference Line power cables are designed
to be used with the worlds finest audio components.
There are three
levels of performance in the Reference Line starting with the Delta v2 NR and
Delta v2 XC models. The Alpha v2 is a level up from the Delta v2 and represents
the best price-to-performance in the lineup. The Sigma v2 takes top honors in
the line for those that must have the best. All three Reference models feature
Shunyata Research’s exclusive VTX-Ag conductors that combine an ultra pure
silver with a concentrically wound layer of OFE copper. This provides the speed
and transparency of silver with the richness, tonal color and power of pure
copper.
Using proprietary conductors and parts developed for the Omega
QR, the Reference NR Series delivers pace-setting performance in each product
category. Noise reduction technology and Shunyata Research’s own CopperCONN™
connectors propel the Sigma v2 NR cable to previously unattainable levels of
performance.
Application: The Sigma v2 NR is an ideal power cable for
source equipment like CD players, DACs, tuners, preamplifiers and it makes an
excellent amplifier cable with its high-current conductors and exclusive noise
reduction capabilities. The Sigma v2 XC is the ideal mate to the Sigma v2 NR to
power your Shunyata Research power conditioner.

EXCLUSIVE NR TECHNOLOGY
Power line noise is an insidious problem that
originates from many sources including the audio components themselves. Shunyata
Research power cords employ proprietary internal noise reduction filters that
measurably and dramatically reduce noise on the power line and and noise that is
produced by the component power supplies.
Shunyata Research’s NR power
cords are used within the scientific community, medical imaging and heart
surgery labs, and many world-renowned recording studios. This noise-reduction
technology was developed by Shunyata Research’s medical division, Clear Image
Scientific, to improve the performance of medical imaging systems in cardiology
and neurosurgery
NR filters are specifically engineered to be
non-reactive and are compatible with all components and power supply designs
including high-power amplifiers.
DTCD™ Analysis is a technique that
measures instantaneous current through low impedance electrical conductors and
contacts. Shunyata Research uses it to optimize the design, specification and
construction of parts and materials to ensure maximum current delivery
performance. Each part, conductor, noise circuit and material inside the Delta
allows for maximum throughput of instantaneous current.
Listeners will
experience earth-shaking low-frequency performance from even the highest-current
amplifiers as well as dynamic contrasts unheard of outside of a live event. More
than any other design parameter, Shunyata Research’s skill at reducing impedance
and improving dynamic instantaneous current is unparalleled.
CopperCONN™
Carbon Fiber
Shunyata Research has developed its own line of CopperCONN™
connects that feature true carbon fiber head-shells. The internal contacts are
culled from solid OFE copper and feature a high-tension, spring-loaded contact
for a vice-like grip. This contributes to a measurable improvement in DTCD™
performance and a correspondingly obvious difference in audible performance.
CopperCONN™ connectors have a measurably lower contact-junction resistance
and are hermetically sealed with an inert compound that protects the contacts
and wires from corrosion. This also ensures that the wires cannot become loose,
fray or pull out from the head shell. This guarantees a lifetime of reliable
performance that does not degrade over time.
ArNi® wire was designed by
Shunyata Research to be the finest quality wire available. It begins with the
highest purity of copper and silver metals available, including Ohno (single
crystal), PCOCC silver and OFE C0101 conductors. Fluorocarbon dielectrics,
usually only found in aerospace applications that have exceptional electrical
characteristics including extremely low dielectric absorption, high dielectric
strength and superb heat resistance. When used in digital wiring it
significantly reduces transient energy storage and release which affects phase
noise performance.
VTX-Ag cables are uniquely constructed with both an
inner, center conductor made of pure silver and an outer concentric ring
conductor made of pure copper. It is made using the finest fluorocarbon
insulation to minimize dielectric absorption and re-radiation which translates
to an improvement in resolution and clarity. VTX-Ag delivers the speed and
clarity of silver and the midrange warmth and three dimensional power in the
lower octaves of copper without imparting any of the negatives associated with
either metal.
Shunyata Research uses only the highest purity of copper
available for the production of its wire products. OFE Alloy 101 or C10100 is
the highest grade of copper with a minimum 99.99% purity and a conductivity
rating of 101% IACS. OFE stands for oxygen-free electrolytic and supersedes the
term OFHC (oxygen-free high conductivity). C10100 is the only grade of copper
that comes with a written certification of purity.
Fluorocarbon
dielectrics are usually only found in wire used in the aerospace industry,
satellites and only the most expensive audiophile cabling. It has special
electrical characteristics; very low dielectric absorption, high dielectric
strength and exceptional heat resistance. When used in audio and power cables is
reduces the perception of dynamic compression and it improves sonic low-level
resolution and clarity.
Simple crimping, soldering, brazing and screws
are all inferior methods of joining two wires or terminals together. Sonic
welding uses high-energy sonic waves to literally join two metals together at a
molecular level and cold-welding uses high-energy pneumatic pressure to bond
metals. Shunyata Research uses both methods to secure connections that do not
degrade over time.
