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\r\n\r\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.

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.

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.
