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 Alpha v2 NR
cable to previously unattainable
levels of performance.
Application
The Alpha 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 Alpha v2 XC is the
ideal mate to the Alpha 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. And finally every cable
undergoes our proprietary KPIP™
process.
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. The best qualities of
silver and copper combined.
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.
Certified by ASTM F68 C10100.
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.
Crystal clear transient detail
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. Superior contact and wire
connections.
Kinetic Phase Inversion
Processing was developed by
Caelin Gabriel after years of
research into the underlying causes
of various effects such as burn-in,
wire directionality and the effects
of cryogenic treatment. He
discovered that there was an
underlying core principle that
burn-in and cryogenics only
partially addressed. Once the
governing principle was understood
it became possible to create a
processor that reduces the need for
long burn-in periods and eliminates
the effects of cryogenic treatment.
Four-days of continuous KPIP™
processing dramatically reduces the
sonic ups and downs associated with
burn-in, delivering a relaxed and
natural presentation.
