Shunyata Research Hydra Alpha Model 2 w/SSF spikes & rubber feet

I'm upgrading to a Shunyata Denali power conditioner so selling my Shunyata Hydra Alpha Model 2 with both the original rubber feet and the $200 upgraded SSF (stainless steel feet) spikes/cups. 

This is the newer Alpha Model 2 which uses the same case as the current Cyclops, rather than the older rectangular pre-alpha Model 2.

It is in perfect shape with only normal signs of use such as dust which sticks to the rubber feet and scratches on the cups from the spikes. The casework is perfect, as is the function. I stuck felt pads to the bottom of the cups, but those are easily removed if you wish. I have the original box for the SSF but not for the power conditioner.

If you need a matching 20A (C19) power cord I have a Shunyata Venom HC which I would sell for $145, but am not including in this listing so that you may choose your own cable.

Add any PayPal fees (2.9%) and shipping costs unless you want to fetch it in person.






Shunyata's writeup of the Hydra Alpha Model 2 was:

The Hydra Alpha 2 is Perfect for Amplifiers!

The Shunyata Hydra Alpha Model 2
incorporates the core MPDA (Multi-Phase Differential Array Filter)
technologies from the Hydra Triton and Talos to deliver exceptional
high-current performance to a wide variety of studio, home media and
entertainment systems. Any system; whether a modest two component system
or a massive studio or home theater set up can benefit from the Hydra
Alpha Model 2's modest size and flexible placement capability. Hydra Alpha Model 2 was designed using Shunyata Research's DTCD measurement analysis to insure that it offers the finest high-current capable performance in the industry.

The Hydra Alpha Model 2 was designed
to benefit ultra-high current amplifiers, projectors, flat screen
video, sensitive source electronics and two component systems of any
type. For those with multiple dedicated lines, the Hydra Alpha
Model 2 can be used to filter noise on second or third circuits that
have remote electronics such as projectors or amplifiers, subwoofers,
analog or digital electronics. From the simplest two-component system to
the most expensive and complex, the Hydra Alpha
Model 2 was designed to deliver high-current capable performance without
the noise and interference common in most home-entertainment
environments.

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.

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.

CDA-101 Copper

CDA 101 copper is the highest purity copper on the
metals market. It comes with papers that prove its authenticity. This is
the only type of copper that Shunyata uses in its electrical products, from signal cables to power cords and power conditioners.
