Clear offers superb dynamics, high frequency extension, and speed, along with perfect control over the entire frequency. Extractsing every detail while remaining musical, it works great in either long or short cable runs.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eClear brings a new approach to conductor technology, applying advanced design, engineering, and metallurgy for unprecedented performance. This same technology is used throughout the Cardas Clear family of cables.\u003c\/p\u003e\n\u003ch4\u003eAdvanced Conductor Design and Geometry\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eClear's conductors use a Matched Propagation Kevlar core, ultra fine Grade 1, 99.9999% pure oxygen free copper with SPN clear coat (Litz), and gauge sizes scaled to Golden Ratio proportions. The conductors range from 41 AWG to 39 AWG. Utilizing ross-field layer geometry, insulated in an ultra thin extruded PTFE jacket.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe advanced geometry features equilateral triad 3 conductors with anti-static LDPE air-tubes bound with carbon impregnated PTFE tape wrap. The outer layer uses PTFE air-tubes scaled 1.618 times larger than the core tubes to suspend the composite shield of tinned copper and magnet wire away from the signal carrying conductors. The cable is finished in an ultra-soft extruded TPR jacket.\u003c\/p\u003e\n\u003ch4\u003e\"The Best Copper on the Planet\"\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eClear boasts conductors made with Cardas Grade One copper, which George Cardas calls \"the best copper on the planet.\" This copper is mined in Arizona, then shipped to a New England factory where it is very S-L-O-W-L-Y drawn into conductors in a process that includes reduction annealing between steps to further purify and meld the copper into what George calls \"the most amazing audio conductor I have ever experienced.\"\u003c\/p\u003e\n\u003ch4\u003e\"Just Spot On\"\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003e\"The interesting thing about the Clear is that it not only sounds incredibly neutral, it manages to do this while maintaining the fulness of sound and the acoustically convincing midrange that the Hexlink did so well,\" observes Christiaan Punter, \u003cem\u003ehifi-advice.com\u003c\/em\u003e, September 21, 2014.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"Focus and soundstage layering is also much improved compared to the Hexlink… It’s not razor-sharp, but just right: not overcooked, not underdone. Some cables portray images so sharply delineated, so etched, that the music loses its natural cohesion and 3D effect. The Clear’s balance between accuracy and musicality really is just spot on.\"\u003c\/p\u003e\n\u003ch4\u003eCardas Clear Technology\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eCardas 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.\"\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"Clear represents the best of Cardas,\" reports Alan Sircom in issue 66 of \u003cem\u003eHiFi+\u003c\/em\u003e 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.\"\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eClear 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.\u003c\/p\u003e\n\u003ch4\u003eThe Trouble is Dielectrics\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eOne 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eWhile 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.\u003c\/p\u003e\n\u003ch4\u003eThe Lagging Charge Problem\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eAt 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eAt 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eSome 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.\u003c\/p\u003e\n\u003ch4\u003eThe Matched Propagation Solution\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eSince 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eA 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.\u003c\/p\u003e\n\u003ch4\u003eA Huge Dynamic Range of Resolution\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eClear 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.\"\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe insights and technology in all the Cardas Clear cables brings a new level of clarity and realism to your listening experience.\u003c\/p\u003e\n\u003ch4\u003eSignal Propagation in a Cable\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eAt 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.\u003c\/p\u003e\n\u003ch4\u003eInterconnects vs. Speaker Cables\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eBecause interconnect cables flow very little current, the 'magnetic shadow' from their magnetic field is tiny compared to their 'electrostatic shadow.'\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eSpeaker 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eHow 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.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eAs 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.\"\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eNulling 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.\u003c\/p\u003e\n\u003ch4\u003e\"They Do EVERYTHING Right\"\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003e\"From the time the first note started playing, I began to hear these cables start to do EVERYTHING right,\" observes Cardas Clear owner enjac26, \u003cem\u003eforum.audiogon.com\u003c\/em\u003e, April 30, 2016.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eSoundstage Width – Check.
