Editors' Choice Award 2019 – The Absolute Sound
Beyond Any Performance You Thought Possible
Clear Beyond speaker cable is simply that, it is beyond the demands of any loudspeaker or amplifier combination imaginable. No impedance dip or current flow demand is a challenge in any way. Clear Beyond is simply overkill for all but the most extreme systems.
Award-Winning Performance
England's hi-fi+ magazine honored the Cardas Clear Beyond Speaker Cable with an Editor's Choice Award for 2024.
"In our test, everything about Clear Beyond was a revelation. We reviewed Clear Beyond interconnects, loudspeaker cables, and standard and XL power cords separately. However, combined in a system, their organic, lithe, and effortlessly fluid qualities worked in perfect harmony."
"The balance and poise of a system sporting Cardas Audio Clear Beyond is remarkable. Detail, dynamics, and soundstaging are excellent, but articulation and coherence are class-leading. Cardas Audio's Clear Beyond unlocks the full potential of high-end audio systems, allowing listeners to experience a more immersive and enjoyable audio experience. The name is apt… there's nothing more Clear than Cardas."
Editors' Choice Award, The Absolute Sound
"This thick blue cable takes the patented technologies in Cardas cables to new heights," reports The Absolute Sound, March 2019, which gave Clear and Clear Beyond an Editors' Choice Award. "The balanced and single-ended interconnects and the loudspeaker cable are functionally identical in sound. But that doesn’t mean a ‘house’ sound; instead, Clear sounds as close as you can get to having no sound. [Clear is] eclipsed in performance only by Cardas Clear Beyond. Where Clear used four conductors, Clear Beyond features eight, meticulously built up using multi-gauge in a 'Golden Section' symmetrical tri-axial design."
"A Dose of That Cardas Magic"
"So transparent is the Clear Beyond, it is the perfect interface for those who want as little between their components as possible," notes Gregory Petan, Positive Feedback Issue 19, June 24, 2022.
"In conjunction with the Clear Beyond's neutrality and the fire hose full of information that it flushes through the system, it also manages to maintain a dose of that Cardas magic that those who are familiar with the brand, have so valued over the years. This may seem to contradict all the above talk of neutrality, implying there is a "sound" related to the Clear Beyond. On an absolute level, that would have to be true. But this is one of those times where I gladly accept the paradox of neutrality and implicit "magic" while sitting back, throwing on some beloved music, and counting my blessing."
"If I had to provide one sentence to describe the Clear Beyond, it would state the greatest attribute was its clear, enveloping, natural musical presentation. Very impressive results indeed," notes Brian Boehler at StereoMojo.com, which honored Clear Beyond its Maximum Mojo Award. While not inexpensive, it represents a 'clear' value among state-of-the-art speaker cables."
Clear Speaker Cables
As standard termination, Clear Speaker Cables use pure billet copper, rhodium plated spade connectors, 'crush forged' onto the cable with a new two-stage process developed by George Cardas.
Clear speaker cables graduate progressively in size from Clear M to Clear to Clear Beyond. The larger cords have more layers and progressively greater lay length variation.
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 represents the best of Cardas," reports Alan Sircom in issue 66 of HiFi+ magazine, "so if you are already impressed with Cardas but want more, Clear could be the first, 'last' upgrade you make, sure in the knowledge that however high up the audiophile ladder you climb, Clear will be there, waiting for you to catch up."
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.
