Performance Very Close to Top-of-the-Line Cardas Clear
Cardas Light interconnect cable uses an elegant application of the breakthrough technology that George Cardas has designed for his top-of-the-line Clear series cables. Compared to Clear interconnect, the conductor used in Light is actually scaled up so that the twists per inch (TPI) can be reduced. This technique halves the construction time compared to Cardas Clear.
Light's dielectric consists of more Teflon and less air than Cardas Clear, eliminating the cost of the thin wall Teflon tubes and associated construction costs. This allows the entire package to be scaled down and overall construction time significantly reduced.
The result with Cardas Light is what George Cardas calls "an interesting product that actually show gains in some areas, such as less dielectric involvement. At the end of the day, we have a streamlined product whose performance is very close to Clear." But Light costs far less!
As part of the Clear family, Light interconnect brings a brand new approach to conductor technology, applying advanced design, engineering, and metallurgy for unprecedented performance. This same technology is used throughout all of the Cardas Clear cables.
Cardas Clear Technology
Cardas Clear cables use newly applied technology that is George Cardas' breakthrough solution to the smeared, unfocused sound that's inherent in standard cable designs. Cardas Clear uses Matched Propagation Conductors to deliver what George calls "an unprecedented window of clarity."
Clear technology is scientifically demonstrable. It presents a 'clear' technical solution to a core problem that is intrinsic to signal-carrying cables (speaker cables, interconnects, etc.) and will quite 'clearly' improve the sound of connected hi-fi and home theater components.
The Trouble is Dielectrics
One problem with standard audio cable designs is that the cable dielectric (also known as cable insulation) produces an electrical effect that interferes with the audio signal. While there is no current flow in dielectric materials, the dielectric accumulates and releases an electrical charge in response to the current flow in the conductor, much like the charging and discharging of a capacitor. But the electrical discharge from the dielectric is out of sync with the electrical signal in the conductor.
While the electrical signal in the conductor moves at the speed of light, the charge propagation in dielectric material is limited to approximately 78 percent of the speed of light. The discharge of the dielectric lags behind the charge in the conductor, causing a smearing of low-level information in the cable.
The Lagging Charge Problem
At very high frequencies, cables can appear to propagate faster because the slower dielectric materials don't have the time to charge at very high frequencies, and the lag is diminished.
At audio frequencies, however, this lag creates a noticeable problem. That's why dielectric manufacturers may brag about what their dielectrics will do at a million cycles per second, but don't talk about what they do at a thousand cycles per second, where the negative effects are audible. Jitter is one directly observable artifact of this conductor/dielectric relationship.
Some cable manufacturers try to compensate for this differential lagging in a cable by adding an electrical network (for example, by using a load coil), but the damage has already been done. Once the low level information in the signal has been smeared, it is lost and cannot be recovered.
The Matched Propagation Solution
Since the so-called 'charge propagation velocity' of the dielectric can never equal the speed of electrical changes in the conductors, George Cardas' ingenious solution with Cardas Clear cables is to slow the conductor to match the rate of the dielectric.
In a concentrically stranded conductor with individually coated strands (such as the constant "Q" conductor used in Cardas cables) the vector velocity and decay time of the conductor can be matched to that of the dielectric by controlling the lay length progression (twists per inch or TPI) of successive strand layers.
A matched propagation velocity conductor of this type, as used in Cardas Clear cables, mitigates the effects of capacitance much as a load coils do, but it does this continuously in the cable rather than at intervals. Eliminating the time delay between storage elements in the cable itself eliminates the bandwidth and dynamic range limitation seen in periodically loaded cables.
A Huge Dynamic Range of Resolution
Clear has a constant transfer characteristic, exponentially lower resonance, and a huge dynamic range of resolution. Its Matched Propagation Conductors maintain low level information and natural transients in a way that no other cable can. It does not exaggerate the leading edge of the signals or smear low-level information as conventional conductors do. Clear maintains the overall time signature of the original sound elements making it easier to pick out what George Cardas calls "the head in the choir or the emotion in the individual voice."
The insights and technology in all the Cardas Clear cables brings a new level of clarity and realism to your listening experience.
Signal Propagation in a Cable
The signal in a cable is propagated two ways: electrostatically and electromagnetically. At high impedances, problems are predominantly related to electrostatics through the transfer of charge in the dielectric. As we've seen, George's matched propagation conductor resolves that issue.
At low impedances, the situation changes. The signal is also transferred as current, because you need current to do work such as moving speaker drivers. So here the magnetic fields are the analogous issue.
Interconnects vs. Speaker Cables
Because interconnect cables flow very little current, the 'magnetic shadow' from their magnetic field is tiny compared to their 'electrostatic shadow.'
Speaker cable problems tend to fall in both worlds, though. That's because the impedance circuit can run from as little as 2 ohms or less in a loudspeaker to as much as 1000 ohms or more in a headphone.
How the magnetic fields interact with their surroundings is affected by the geometry of the cable. This is where Cardas Clear's constant "Q" conductors and Perfect Mirror Quadaxial (an application of Matched Propagation Technology) construction come into play.
As George explains it, "Perfect Mirror Quadaxial construction nulls the magnetic field of the cable from the perspective of the universe that surrounds the cable, so that the shadow of the cable's electromagnetic activity is not reflected in the signal."
Nulling the effect of the magnetic field removes one more cause of distortion from the musical signal. Combined with their groundbreaking elimination of differential lagging in a cable, Cardas Clear's constant "Q" conductors and Perfect Mirror Quadaxial construction create a cable that is breathtakingly clear, as the name suggests -- a cable that will let the full potential of your source material and system shine through.
