The basic building blocks
of a Cardas cable have been constant since day one:
Our own, Ultra Pure Copper, produced using our proprietary method. Multi-stranded Litz
conductors, with strand size varying in Golden Ratio steps. Top quality dielectric ma-
terials and innovative air-tube dielectric suspension techniques. Premium connectors
machined from copper & brass, plated with silver, and a flash of rhodium. Terminations
performed by skilled craftsmen, using Cardas Quad Eutectic Solder and Cardas Rosin
Flux Soldering Paste. These design elements were present in the original Cardas
cables, like Quadlink & Hexlink, and former flagships such as Golden Cross & Golden
Reference.
Our Clear cable line combines all of this with Matched Propagation Technology, the
subject of George’s most recent patent (US Patent 7,674,973), which matches the propaga-
tion rate of the conductor to that of the dielectric, eliminating time-smear distortion, improving
musical integrity and dynamic range.
Cardas Copper
At the heart of a Cardas cable is
our Ultra Pure Cardas Copper. Mined
in the Southwest USA and processed
in
the Northeast, we employ proprietary
drawing and annealing techniques
to create the highest quality, purest
copper strands. A Single Poly-Nylon
coating is applied to prevent oxidation,
and eliminate crosstalk between strands.
Viewed through a microscope, typical copper wire appears
shredded and interleaved with impurities.
Cardas Copper, however, is drawn & annealed very slowly
through Silver dies, in an Oxygen free, Hydrogen reduction
atmosphere. The result is grain free, perfectly smooth and
99.9999% pure Copper strands.
In addition to our own cables, Cardas Copper is used by other
high-end audio manufacturers, and in scientific applications.
Matched Propagation
The subject of George’s 2008 US Patent (7,674,973), our
Clear product line features Matched Propagation Technology,
in which the propagation rate of the conductor is controlled
through its internal geometry to match that of the dielectric
material. These conductors overcome
challenges dating back to the early days
of the telephone. However, whereas
those conductor/dielectric mismatches
were dealt with using network boxes,
Matched Propagation Conductors
solve the problem within the cable itself
- keeping the signal intact the entire
way, rather than attempting to fix it
after the fact.
Terminations
Terminating, or “putting a connector on” a Cardas multi-strand-
ed Litz conductor requires skill and special equipment. We
use our own Cardas Quad Eutectic Solder and Cardas Rosin
Flux Soldering Paste, along
with 800ºF (427ºC) irons
& 700ºF (371ºC) solder
pots. Our flagship speaker
cables are terminated with
a solder-less, compression
die forging process in which
the copper of the conductor
and connector fuse together as one. These procedures are
performed by our talented staff of Cardas Terminators, with
decades of combined experience.
Golden Ratio Scaled Conductors
As implied by our Nautilus Shell logo, the Golden Ratio is ap-
plied to many Cardas products, including our Litz conductor
designs. In a Cardas multi-
stranded Litz conductor, the
smallest wires are at the cen-
ter, with each layer increasing
in size at a Golden Ratio step
(1:1.618). This innovative
micro resonance control
technique was the subject of
one of George Cardas’ first US patents, and is present in all of
our cables & chassis wires.
Cardas Connectors
Cardas connectors are machined from billet copper or brass,
and plated with silver and a flash of rhodium. In addition to
our own cables, Cardas connectors can be found on some of
the finest equipment in the world.
