New Product Announcements

Revelation Audio Labs "reverse" I2S cable
Empirical offers a custom version of Revelation Audio Labs I2S cable. This cable can
be used between Off-Ramp I2S or Pace-Car and a Northstar DAC. Improves on detail and
liveness over our own twisted-pair cable and it's actually longer for more convenience.

Top Fuel Power Cable
Empirical offers a new reference power cable, the Top Fuel. This is the one we bundle
with our Spoiler DAC. Superb, uncolored power cable. Highly recommended for DAC's
as well as amps and preamps.

Empirical donates a Pace-Car for AirPort Express to the Enjoy
the Music Audiophile Equipment contest:

Pace-Car reclocker for Squeezebox, Sonos, Northstar Transport,
AirPort Express, Olive and All Empirical USB converters
The Pace-Car Type 1 and 2 are available. Type 1 can be used with Squeezebox,
Sonos, Olive, Northstar Transport and other Transports and PCI cards
that have Master, Bit or Word Clock inputs. This transforms a Squeezebox into a
world-class contender.

Type 2 can be used with USB converters including the Freeway I2S, Freeway 2,
Off-Ramp I2S, Off-Ramp Turbo 2 and AirPort Express. It can even be used straight
from a S/PDIF from a laptop. The Type 2 versions must be tuned to the particular
laptop and may not work with other laptops.

All things that go through the Pace-Car end-up the same high-quality at the outputs.

Rev 3 of the board can support inputs including:

I2S or Toslink and S/PDIF or AES

Outputs are:

I2S and S/PDIF or AES

Freeway 2 and Freeway I2S getting new clocks
A new oscillator with extremely low jitter will be going in all new Freeways.
This oscillator adds $10 to the price of a new Freeway and the benefits are
worth at least $200. Really outstanding. Existing Freeway 2 and Freeway I2S
can be upgraded for $125 including shipping. Older Freeways based on the
Transit are not compatible. The Off-Ramp is still a bit sweeter sound with the
Superclock4, but the Freeways are getting closer.

"Driverless" Firmware now available for Off-Ramps/Spoiler
We have finally licensed our own version of the "driverless" firmware made
famous by Benchmark Media Systems. This requires no driver on either PC or
MAC and is Vista compatible. It supports 24/44.1 through 24/96 transparently.
All new Off-Ramps and Spoilers will have the new firmware installed. It does not
support AC3, so if you want to use it with movies, then we can still provide the
M-Audio driver and firmware. Upgrades to existing Off-Ramp I2s, Off-Ramp
Turbo 2, Freeway2 and Freeway I2S can be made for $125 including shipping.
Older Off-Ramps and Freeways based on the Transit board are not compatible.
Please schedule the upgrade by email. We will try to knock-out 1-2 per week
between mods and in our "spare-time", which is non-existant ;>)

For those that do not upgrade, please try out this new method for playback:

Update Turbomod for the Benchmark DAC-1
This one is a must-have. It eliminates much of the vocal harshness of the DAC-1
as well as improving the depth of image. 6-moons review did not have this mod.
Vocal smoothness is similar to the Northstar DAC after this mod.

Northstar 192 DAC and transport mods added
The Northstar 192 DAC is based on the Crystal D/A chip. This implementation
uses the best currently available 24/192 upsampler chip and has discrete
transistor output. The real interesting thing about the Northstar is the native
I2S interface. It is compatible with the Off-Ramp I2S and an I2S-output Northstar
Transport. It allows one to get into I2S interfaces using either Transport or
Computer. The mods for the DAC-1 are also simpler and less expensive, making
it the most cost-effective world-lcass solution.

USB extensions
We recommend active UBS hubs or the Opticis at this time:

http://usb-shop.com/opticis.html

The Belkin Wireless USB Hub is available now as well as the WiRanger.
Both of these add significant jitter, so we recommend a Type 2 Pace-Car
if you plan to use either one.

The coolest interface is to use Mac and control iTunes to drive USB using your
iPhone or an iPod Touch. See our forum on Audiocircle.com for more info.

Positive Feedback Review

"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"

Why choose Empirical Audio for Mods?
  • Experience - 30 years digital design
  • Education - EE degree - Analog
    and Digital emphasis
  • Knowledge - Industry training on
    power delivery, transmission-lines,
    grounding/shielding, ESD, signal
    integrity and rework techniques for
    surface-mount and through-hole.
  • High-quality professional rework

Empirical mods combine an engineering knowledge of power
delivery, signal transmission, circuit analysis and cable
design to deliver significant audible improvements to you
at an excellent value. We are able to leverage almost 30 years
design experience (as a EE) with signal transmission,
interface design and digital electronics. This is how we are
able to improve nearly any component, including crossovers
and even PCI cards. We are uniquely qualified to reverse-
engineer component designs and make them better. Our
mods typically make dramatic improvements because they
are holistic changes.

Our mods are different because they are wholistic in nature. We
evaluate all of the compromises that were made in the original
design and redesign these. Typical consumer products are
designed to a "price-point", which results in compromises and
trade-offs that ultimately impact the quality of the sound.
Consumer gear is also designed for high-volume manufacture
which usually means circuit board wiring and minimizing hand-
soldering and cabling. Circuit-boards are made of inferior
dielectrics and the current paths are less than optimum due to
ground-plane construction and routing constraints. In most
cases, external cabling will improve these. Because hand-
soldering is eliminated in most consumer products, high-quality
"through-hole" components are sometimes avoided. All of
these compromises can be reversed with appropriate mods.
In addition, we have found that even the best analog circuit
designers tend not to be proficient in the more esoteric areas
of design, namely power delivery, grounding, return paths,
wiring, shielding and transmission-line effects. It is in these
areas that we make significant sonic improvements and these
areas where Empirical Audio has extensive training and
experience.

Experience the difference with an Empirical Audio mod. You
do not see very many EA modded items for sale on Audiogon.
The reason is that most customers keep them. In fact, we have
helped many customers reach their personal audio nirvana and
then we never hear from them again, even on the discussion
groups. They are finally able to transition from critical listening
to enjoyment listening. They stop listening to the components
and start listening to the music. This is what we are about.

 
"the improvement was
immediate, noticeable,

in all its glory like spring
flowers bursting forth
in mountain rocks.

Bare Wire Technology
Unlike other designs, Empirical Audio cables utilize
Bare
Wire Technology (BWT)
. BWT is a result of ten years of
developing methods to process and suspend bare wires.
Bare wires significantly reduce signal dispersion (smearing).
Signal dispersion is caused by the dielectric absorption of
solid insulating materials that are used in conventional
cables, such as Teflon or PVC.
Dispersion can cause:
  1. Haze and lack of image focus
  2. Bloated bass, not "tight"
  3. Not enough impact from kickdrum and Bass
  4. Lack of soundstage width and depth
  5. Poor dialogue and lyric intelligibility
  6. Acoustics, particularly guitar, harp
    and mandolin just don't sound live

If your audio system is suffering from the above symptoms,
Empirical Audio is your solution. Our cable designs combine
optimized electrical characteristics with BWT and smart
metallurgy
to bring you dynamics, inner detail and
soundstaging beyond anything you have experienced.

Our philosophy is to make the selection of cables easy for
our customers. In order to enable this we simply offer our
best current designs. We may continue to offer older or less
expensive products if they are very popular, but in general
when we develop a superior design, we discontinue the
current version. We have found that most of our customers
want the best we can offer and tend to upgrade anyway.
Our goal is to deliver the most accurate, musical sound that
we can to our customers.

Empirical sells both direct from this website and through
select Dealers. Special orders (lengths and terminations etc.)
are accepted by Email. Email us for Dealer locations.

                 
  We Have Moved

We have relocated the business to central Oregon, a place called
Black Butte Ranch. BBR is in the Cascade mountain range of
Oregon at an altitude of 3300 feet. It is a full-service resort
complete with golf courses, bike trails, horse stables and great
fly-fishing. BBR has hundreds of great rental houses and condos
for vacationers. Here is their link:

  Grand Slam Power Cord

This is the power cord we had been hoping for. It has the low-
inductance of the Magnum2 combined with the clarity of the
Clarity7 speaker cable. It is our first power cord to use
BWT
(Bare Wire Technology). For amplifiers, it takes them to a new
level. The Grand Slam improves clarity, dynamics, background
quietness and coherence. The coherence and background
blackness are the big improvements over our original Magnum2
power cord. The Grand Slam comes equipped with a silver-plated
AC plug, which synergizes beautifully with Acme silver-plated
outlets. The IEC is UP-OCC copper, with direct 24 karat gold plating.
Its a lot fatter than our original Magnum2, but it flexes just as
well and bounces right back. Like all Empirical Audio products,
it is built to take abuse.

 
  Silver Bullet Plugs for Holophonic-PC

Empirical has added these outstanding plugs from Eichmann in
Australia. They are truly a breakthrough, being the only solid pure
silver plugs on the market. We noticed an improvement in sound
clarity compared to the standard Bullet Plugs.
