Au24 High Resolution Audio Cables
We believe the Au24 cables
attain the elusive goal of combining exquisite sonic detail
with the beauty of true musicality. This is due in large part
to the Au24’s incredible time domain performance. One
look will tell you these are not "me too" products.
The materials, design and construction techniques utilized
in the Au24 cable line reflect the latest thinking in state
of the art, high-resolution technology.
Contributing to the excellent time domain
characteristics of the Au24 cables are high quality materials
and proper configuration. Most audiophiles are aware of the
importance of good insulating and conducting materials. The
Au24 cables are constructed of OHNO continous cast single
crystal copper conductors with polypropylene insulation and
cross-linked polyethylene jacket material. Relatively few
people are aware of the role geometric configuration plays.
If a given cable is not optimally configured to perform the
task it was designed to do it will never sound as good as
a cable with the correct physical/electrical characteristics
regardless of which exotic materials are used in its construction.
All Audience cables and especially the Au24 series are designed
for low eddy-current resistance. This is the key electrical
characteristic for good time response. Eddy-currents are created
by the magnetic field found around a cable when an electrical
signal is present. This magnetic field builds up and collapses
as the signal varies. When the field collapses it induces
an opposing voltage back into the cable. This opposing voltage
causes eddy-currents in the conductor. If they could be seen,
eddy-currents would look like swirling water in a river. This
late arriving, opposing voltage disrupts the original signal
by inducing a time-smearing artifact. These effects are clearly
audible. Cables that sound "detailed" or "powerful
in the bass" are usually victims of high eddy-currents.
Eddy currents plus high capacitance can cause a cable to sound
overly "relaxed." The particular type of coloration
caused by eddy-currents is dependent on the materials, construction
techniques and the geometric configuration of the cable. The
Au24 cables exhibit extremely low eddy–current resistance.
Many cables are designed for the lowest possible
capacitance. Other cables are designed for the lowest possible
inductance. Actually, for properly balanced sound reproduction
these inductive and capacitive values should both be minimized
and the ratio of inductance to capacitance (L:C) must be optimized.
By designing for the lowest possible eddy-current resistance
at the correct specific frequency, proper L:C ratio is naturally
arrived at and both of these properties are minimized. The
result is natural reproduction as heard in real life without
added emphasis or editorializing. The Au24 cables may not
sound as exciting at first but the virtues become apparent
as the listener becomes familiar with them. Perhaps even more
importantly, the musical overtones arrive in their proper
time relationship with the fundamentals. This creates a more
convincing illusion of reality and improves sound staging.
For example, when properly recorded, a drummer’s cymbals
will now be placed back with the rest of the drum kit instead
of appearing to emanate from the speakers.
There is a common misconception that loudspeaker
cable must be large in diameter and have a low DC resistance
in order to provide good bass response. DC resistance is relatively
unimportant. What really matters is the characteristic impedance
(AC resistance) of the cable. Music is an AC signal after
all. Most of these large diameter/low DC resistance cables
have excessively high characteristic impedance anywhere from
100 to 600 ohms with some measuring in the 1000’s of
ohms. The Au24 Loudspeaker Cable is only 4mm or 1⁄4"
in diameter. Although the DC resistance may be slightly higher
than the garden hose variety speaker cables the characteristic
impedance is only 16 ohms. Musical signals from the bass to
the overtones pass through this cable with less actual impedance
than a cable with a lower DC resistance. The Au24 Loudspeaker
Cable provides nearly perfect bass timbre and extension. Plus,
the low eddy-current resistance means the cable is very quick
and linear in the time domain. Voices and instruments sound
strikingly real with this loudspeaker cable.
In developing the Au24 line we discovered
how important simplicity is when highest possible performance
is the design goal. Fancier connectors and layers of cosmetic
sleeving would have made the cable look more expensive. However
every time we made it look better it sounded worse. We were
truly amazed at the sonically detrimental effects caused by
bulky, high-end connectors and decorative sleeving. The lessons
learned with the Au24 cables have now been applied to our
lower and mid-priced cables as well.
Audience exclusive Au24 RCA connectors are
used on all cables requiring RCA termination. These simple,
high quality connectors are far less colored than bulkier,
fancier connectors. They are an advanced, minimalist design
and have excellent grip and low contact resistance.
Audience balanced analog and AES/EBU digital
interconnects are terminated with Neutrik XLR plugs.
Audience loudspeaker cables are terminated
with rhodium plated spade connectors.
Audience will provide custom lengths and termination.
The Au24 cables will begin to sound good
after 2 to 3 hours playing time and will continue to improve
for approximately 50 hours.
