Shunyata Research Hydra AV Awesome Conditioner nice condition

I have been working my way up the Shunyata conditioners. I went from the PS8, to the Hydra AV. Just purchased a Denati So I need to sell the Hydra Av. It is in good condition with minor scratches on the stainless steel. No deep scratches, dents or scratched paint. It is complete with the original box an all original packing and will be shipped in the Shunyata outer box I came in. (double boxed) Warranty card NO POWER CORD

The shipping cost does not include insurance when calculated by AudioGon. Shipping will be calculated after purchase. I will charge the exact shipping cost after the purchase.

Construction
Although there is a large physical difference between
the Hydra AV and its progenitor -the Triton- these two units are
actually nearly identical internally. Both feature Shunyata’s patented
MPDA, NIC & ZP-PDS technologies, Carling EM breakers, SR-Z1 outlets
and 20Amp IEC inlets. To keep the price of the Hydra AV down and
physical size to a minimum, Shunyata specified a folded 14Ga stainless
steel chassis. Strong and elegant, this chassis is vastly less expensive
than the Triton’s thick aluminum faceplates and multi-panel square
steel chassis parts. This makes the Hydra AV Shunyata’s biggest “bang
for the buck” power conditioner ever.

History
For over a
decade, Shunyata conditioners have graced the world's best systems, with
substantial and unabashed acclaim from critics, industry professionals
and music lovers. Introduced in 2011, Shunyata’s Triton delivers a broad
array of new technologies that are absolutely unprecedented in the
audio industry. Although these concepts are groundbreaking and
revolutionary, the underlying premises having been tested and refined
over 10 years. In 1999, Shunyata unleashed the original Hydra, turning
the entire audio world on its head and garnering dozens of accolades in
the process. Since then, Shunyata’s Hydras have dominated the power
conditioning market with an unbeatable combination of outstanding sound
quality, staggering dynamic range and unprecedented transparency and
tonal accuracy.

Caps & Coils
A typical power supply
generates noise at various frequencies. A typical power conditioner uses
a combination of capacitors or inductors in an array to attempt to
minimize noise. This is like using a chainsaw for brain surgery, a
clumsy brute force approach which has damaging and unintended side
effects. Capacitors, all of them, regardless of type, grade, material or
date of manufacture have a resonant point. In other words, at certain
frequencies, the capacitor starts to vibrate or ring. This can be heard
in recordings with sharp pitch signatures, such as a bell or a piano,
where the capacitor ringing appears as a pinging echo which follows the
original event. Ringing can even change the timbre and tone of the
system. Some manufacturers use inductors (coils) or ferrite elements to
dull the resonance of the capacitors, but this further complicates
matters by masking the problem, rather than solving it. Shunyata’s MPDA
solution is more elegant and effective.

Multi-Phasic Differential Array (MPDA)
MPDA
is an array of micro-filters, each element targets a very specific
noise component. Each element acts like a notch filter, eliminating very
specific frequencies of noise without affecting the broad spectrum; the
technical term is “High Q, Narrow Bandwidth Filter”. Using Surface
Mount Technology, Shunyata is able to place 30 of these high-powered
elements onto a circuit board smaller than a stick of gum, virtually
eliminating noise and without interfering with the conditioner’s massive
current delivery. Most importantly, MPDA eliminates the use of
capacitors and inductors.

Noise Isolation Chambers (NIC)
The
most visible and striking features inside the Hydra AV are the NICs,
three massive cylindrical chambers stacked in a pyramid inside the
chassis, which deliver an enormous step forward in power-line noise
elimination. NICs filter out noise in the megahertz and gigahertz range
without slowing down AC current delivery. Made from pure copper, a
single wire enters and comes out of each tube, one each for hot, neutral
and ground, one wire per cylinder. Each tube is filled with Shunyata’s
patented ZrCa-2000compound, a proprietary material whose unique
molecular structure literally devours noise. Shunyata previously used
this compound on both the Hydra 8 and the V-Ray, but these new NICs are
vastly more powerful as they encapsulate each wire, ensuring ideal
coverage and maximum contact area. The Hydra AV uses the NICs from the
Triton, shortened and stacked in a triangle to fit inside this narrower
chassis.

Zero Point Power Distribution System (ZP-PDS)
Shunyata
has always taken their conductive metals seriously, carefully
auditioning and testing every conductive element in the chain to ensure
proper signal integrity and durability. Shunyata now uses exclusively
high-copper content brass alloy for the conductive chain; every screw,
buss bar, fastener, custom termination and end cap. Although other
metals might have higher conductivity, each requires some form of
electro-plating to keep it from oxidizing or wearing. Plating materials
like gold, silver and rhodium each have their own sound; coloring and
distorting the signal. Brass is durable, highly conductive and most
importantly doesn’t need to be plated for corrosion resistance,
eliminating potential sonic character changes. Using a single metal
through the entire buss system also has substantial electrical benefits,
greatly reducing resistance and lowering the impedance to negligible
levels, thus improving conductivity and allowing power to flow freely.
This is especially important in a compact device such as the Hydra AV as
ZP-PDS improves conductivity and reduces parasitic losses due to excess
heat.

VTX Wire Geometry
Long known for ultra-complex wire
geometries which measurably improve conductivity and desirable
characteristics, Shunyata has developed a new geometry specifically for
use inside this new series of conditioners that greatly reduces the
so-called “skin-effect”. Skin-effect is a distortion caused by differing
speeds of conductivity between the center of the conductor (where the
bass travels) and the outer part or skin of the conductor where the
midrange and treble travel. Skin-effect plagues both stranded and solid
core wire, causing smearing, timing and phase errors, in some cases even
changes in tonal balance. The ideal conductor is a hollow tube, but
this is wildly impractical in the real world, so using DTCD analysis,
Shunyata created a new type of wire geometry which is a “virtual tube”
greatly reducing skin effect and improving conductivity.
