"Instrumental tones seemed
purer and more direct with the
Empiricals"

"... because of the clarity
between the players, as well
as of the space surrounding the
orchestra the overall sonic
picture seemed more realistic."

"I heartily recommend giving
the Empirical Audio Holophonic
interconnects and Clarity
speaker cables a try.. What
they are is very, very good and
well worth a listen."

 Holophonic-PCTM Single-Ended Interconnects
Holophonic-PC interconnects are our new reference for SE analog
interconnects. This is absolutely the best sounding interconnect
that we have ever developed. The bare conductors cause less
dispersion (smearing) in the audio signal than fully or partially
insulated conductors, improving both high and low-frequency
resolution, focus and dynamics. Holophonic interconnects have
bare conductors with air dielectric between them, achieving the
extremely low capacitance per unit length. The low capacitance
of the Holophonic prevents degradation of dynamic, transient
music passages, while preserving detail. This makes the
Holophonic exceptional for use with passive line-stages and tube
equipment. 99.99% pure Silver conductors in a custom stranded
configuration optimize high and low-frequency response by
minimizing skin-effect and stranding effects. If you are looking for
the ultimate in detail without high-frequency brightness or
sibilance, this interconnect delivers this in spades.
Perfect Crystal (PC)
Perfect Crystal silver is created by using more processing steps in the
fabrication of the conductors and assembly of the cables. Perfect
Crystal provides extremely low sibilance and improved focus resulting
in more bass impact. PC silver also makes female vocalists sound
liquid and live, not hissy. Systems that are already overly bright are
excellent candidates for PC silver. PC silver does not have that
characteristic high-frequency brightness or sharpness generally
attributed to silver wires. This results in detail and blackness between
instruments without sibilance.
"There is no haze. The image
is totally focused. Bass is
just slammin’. The soundstage
is unbelievable."
 Holophonic-PC unshielded interconnects are terminated with
Eichmann Bullet* RCA-type connectors which have heavy direct
gold-plated Tellurium-Copper contacts or in the Solid Silver version.
Both types insure reliable long-term connections. The center connector
contact is hollow, further reducing skin-effect.
"The song was alive, the
instruments were alive.
Strings were perfectly
reproduced, with that shimmer
of vibrating air you normally
only hear at live concerts."

 Oxidation of bare-wire conductors is a concern of some audiophiles.
We have never experienced any degradation of our interconnects over
time due to oxidation. This is because silver oxides are generally good
conductors. However, just to insure that more harsh environments do
not cause degradation over time, the conductors in Holophonic interconnects
are sealed in an air-tight chamber with corrosion inhibitors inside. Holophonics
require 10-20 hours of play-time to fully break-in.
Silver Bullet Plugs are available at extra cost. We found these to raise
the performance of the Holophonic-PC to a new level. The Silver Bullet Plug
is truly a breakthrough technology because it is the first solid silver RCA
connector that solves the problem of the outer contact spring. Since solid
silver is so soft, it needs a separate spring in order to allow multiple matings.
The Silver Bullet Plug solves this by supporting the outer contact with
springy plastic.
"I have found the sound of
the Empirical Audio custom
cables to be faultless,
without any sonic anomaly
that I have been able to
detect. Given the fact that
the EMM Labs is my current
reference for SACD/DSD,
and given the fact that my
other cables are the likes
of reference-grade JENA
Labs, Cardas, and Kimber,
this is very high praise for
Empirical Audio and their
"Bare Wire Technology"

 Holophonic-PC's simply bring the music to life, even mediocre recordings.
The highs are like a breath of fresh air and the bass is tight, articulate
and punchy. If you don't feel the bass guitar and kick-drum in your gut
now, you will with these interconnects. CD's, DVD's and SACD's simply
sparkle with clarity. Those lyrics that you never could understand in
your favorite recordings will become highly intelligible, even the lyrics
that the backup singers are singing. No more need to pull-out the CD
jackets to understand the lyrics anymore. Holophonic interconnects
are so spectacular that it is difficult to put it into words. Holophonics
will unlock the performance potential of your components!

Holophonic-2SPCTM Single-Ended Shielded Interconnects
Holophonic-2SPC shielded interconnects are identical in design to
the Holophonic-PC, but are double-shielded (2S) and terminated with
shielded RCA-type connectors. In addition to all of the advantages
of the Holophonic, the Holophonic-2SPC lowers the noise floor achieving
the "jet-black" background that many audiophiles desire. To minimize
the capacitance, a double-layer of shielding (foil and braid) is spaced
away from the conductors. Like the Holophonics, bare conductors are
spaced in an air dielectric which causes less dispersion in the audio
signal than fully or partially insulated conductors, improving both high
and low-frequency resolution, focus and dynamics. Pure 99.99% Silver
conductors in a custom stranded configuration optimize high and low-
frequency response by minimizing skin-effect and stranding effects.
Top of the line machined OFC (Oxygen-Free Copper) RCA connectors
with heavy direct gold-plating terminate the ends, insuring reliable long-
term connections.
  Holophonic-2S is recommended for systems that have radio and
TV transmission towers in close proximity. It is also an excellent choice
for phono to preamp interconnects, since this connection usually
requires shielding due to the high-gain required. The combination of
excellent shielding and extremely low capacitance achieves a level of
impact, detail and pitch-black background that makes them worth 5
times more than our asking price, so our customers tell us. If your
location does not require shielded interconnects, we recommend the
unshielded Holophonic-PC above because their capacitance is even lower.
Since the shield is only connected at one end, this makes them
directional. They are marked to indicate the usual best direction when
used from preamp (source) to power-amp (destination). However, since
this is somewhat system-dependent, we recommend that customers try
them in both orientations to achieve the best results.
  Oxidation of bare-wire conductors is a concern of some audiophiles.
We have never experienced any degradation of our interconnects over
time due to oxidation. However, just to insure that more harsh
environments do not cause degradation over time, the conductors in

Holophonic-XPC Balanced Interconnects
Holophonic-XPC is truly a breakthrough in balanced interconnects.
Our customers have told us that the Holophonic-XPC competes with
interconnects costing 5-10X more, giving it an excellent price/
performance ratio. We believe Holophonic-XPC is the most resolving,
accurate balanced interconnect on the planet.

Holophonic-XPC Balanced XLR interconnects are identical in design to
the Holophonics, with addition of a third heavy copper ground conductor.
The Holophonic-XPC is terminated with silver-loaded solder to Neutrik XLR
connectors with gold-plated contacts. The ground wire is connected at
both XLR connectors providing a ground connection through the
interconnect.
"Details, there are tons
of new details. Treble is
sweeter and more extended.
In my system your cable
does wonders with voices,
they become natural,
present, and you can hear
all their nuances without
being overly analytical in
the process. I am surprised
how musical the
Holophonics are..."

 Holophonix-XPC uses bare conductors which are spaced in an air
dielectric. This causes less dispersion in the audio signal than fully or
partially insulated conductors, improving both high and low-frequency
resolution, focus and dynamics. The low capacitance of the Holophonic-
XPC prevents degradation of dynamic, transient music passages, while
preserving detail. 99.99% pure Silver conductors in a custom stranded
configuration optimize high and low-frequency response by minimizing skin-
effect and stranding effects. Holophonic-XPC signal conductors are also
identical in geometry and length equalized. This is critical in a balanced
interconnect because any skew, material or geometric differences
between the two conductors can cause continuous distortion in the
signal. This is because balanced signaling derives the signal at the
destination by subtracting the two signals electrically. If the two signals
are not in phase, the resulting signal will contain significant distortion
products not present in the original signal.
  Oxidation of bare-wire conductors is a concern of some audiophiles.
We have never experienced any degradation of our interconnects over
time due to oxidation. However, just to insure that more harsh
environments do not cause degradation over time, the conductors in
Holophonic-XPC interconnects are sealed in an air-tight chamber with
corrosion inhibitors inside.
  Balanced Interconnect Basics:
Single-Ended interconnects have a two-wire system as opposed to the
Balanced three wire system. In Single-Ended interconnects, the signal
wire and the ground wire (or shield in the case of coaxial construction)
form a complete circuit, so both conductors carry signal currents. The
ground wire or shield also serves the purpose of bringing the potential
of the two components to the same level.

Balanced interconnects have three conductors, two for carrying signal
currents and one for grounding the two chassis together. Current flows
in the two signal conductors, but not in the ground conductor. One
signal conductor carries a plus signal and the other a minus signal. The
two signals are inverted versions of each other. Both + and - signals
are used at the component input to resolve the signal by subtracting
the two signals. The advantage of this subtraction is that any noise
that is common and the same polarity on the + and - signals will be
subtracted-out. This is know as "common-mode" noise. Most 60 Hz hum
and sytem-caused hiss is common-mode as well as some RF that might
be picked-up. Balanced connectors also have the advantage that there
is a male and a female connector, so they cannot be plugged in wrong
and the connectors themselves are mate-able allowing longer lengths to
be built from shorter lengths. The pin convention most often used is +
on pin 2, - on Pin 3 and ground on pin 1. This is the way that stock
Holophonics are wired.

Our experience in testing a variety of different components with
balanced inputs and outputs has convinced us that low-capacitance
interconnects are just as important in balanced configurations than in
unbalanced (single-ended) configurations. It is a widely held perception
that balanced IC's can be longer than SE without degradation. This is
simply not true. The only advantage of balanced over SE is the inherent
noise rejection properties. Whether balanced is the optimum solution for
your particular system is dependent on the design of the balanced inputs
and outputs of your components. We recommend that you audition both
configurations and choose the one that sounds better.
