The matched propagation design comes as close to perfection as any cable ever envisioned. The connectors and the connection techniques are unequalled in the industry. \u003c\/p\u003e\n\n\u003cp align=\"justify\"\u003eTermination consists of a USB connector on one end and a serial bus USB connector on the other end. For digital signal transmission, there is no better conduit of delicate high-frequency data streams than Cardas Clear. \u003c\/p\u003e\n\n\u003cp align=\"justify\"\u003eClear USB benefits from the benefits and discoveries that George Cardas brings to analog cables in the new Cardas Clear series. According to George, with Cardas Clear USB Cable, \"There is some optimization to the format the conductors have a damping strand incorporated to prevent the spread of unwanted computer clock signals into the audio portion of the system.\" \u003c\/p\u003e\n\n\u003cp align=\"justify\"\u003eThe following information applies primarily to Clear analog cables but still provides an insight into the innovative approach of the Clear series in general. \u003c\/p\u003e\n\n\u003ch5\u003eCardas Clear Technology\u003c\/h5\u003e\n\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\n\u003cp align=\"justify\"\u003e\"Clear represents the best of Cardas,\" reports Alan Sircom in issue 66 of \u003ci\u003eHiFi+\u003c\/i\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\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\n\u003ch5\u003eThe Trouble is Dielectrics\u003c\/h5\u003e\n\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\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\n\u003ch5\u003eThe Lagging Charge Problem\u003c\/h5\u003e\n\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\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\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\n\u003ch5\u003eThe Matched Propagation Solution\u003c\/h5\u003e\n\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\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 \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\n\u003ch5\u003eA Huge Dynamic Range of Resolution\u003c\/h5\u003e\n\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\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","brand":"Cardas","offers":[{"title":"New","offer_id":45981452697773,"sku":"NEW-CRCLESB-4.5","price":540.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3708\/1773\/files\/CRCLESB__47506.1690489249.386.513__27874.1697652141.1280.1280.jpg?v=1778110453","url":"https:\/\/www.audioadvisor.com\/products\/cardas-audio-clear-usb-cable-usb-a-to-usb-b-4-5-meter","provider":"Audio Advisor","version":"1.0","type":"link"}
