Working principle

Without noticing we are in a very polluted environment. Everywhere around us fields arise from currents flowing through conductors, signals from radio stations/mobile phones and other communication networks. Electromagnetic interference is not visible to us,  it's just there. Each device using energy causes fluctuations on the network in the form of peaks or surges, or causes a variation in the electromagnetic fields in the air. The effects occur around the device itself and on its mains supply, but even far away from the device the fields are still measurable. This can only be measured with suitable equipment, not with our ears.

Common thought is that shielded power cords protect the connected devices better against influences from outside, and that is true. But much more important is that the field created by the fluctuating current inside the power cord itself does not reach interlinks in the neighbourhood. Interlinks transport small signals to audio devices with a high input resistance. This high input resistance makes equipment extremely sensitive to interferences.

​

Many power cords for audio purposes look beautiful, just like ours. But appearance is not all! The Current Conductor is a dual-shielded cable. The outside shield is NOT braided steel (a steel screening does not function as a shield but is meant to protect the cable against physical force). Instead, the Current Conductor has a braided high density COPPER screen with tin protection against oxidation. Under the tinned copper shielding lies a 100% closed aluminium foil for suppression of high frequencies. In contradiction to a synthetic foil, this solution works!

The OFC (Oxygen Free Copper) stranded wires are suitable to conduct high currents without resistive losses (the losses of energy in the form of heat). The earth wire is connected at both sides, the shield is only connected at the feeding side, as it is supposed to be. Finally, we gave the plug a nice CNC machined hood.
