From the manufacturer:
This is among the world's finest cables! How can I make such a claim? One listen and you will know why. Active cables are dead quiet due to an electrical charge which is applied to the shield surrounding the signal wires. The shield acts as an electro-magnetic device, pulling in unwanted RFI/EMI pollution. Removing this pollution creates a black background which allows minute details which you have never heard before. Holographic is the best way to describe the effect. Three dimensional with exact instrument placement and the blackest background that you have ever heard, guaranteed!
Many audiophiles mistakenly believe that by using an active shield, the resulting sound is manipulated and will sound artificial and colored. Just the opposite is true. By surrounding the signal with an active shield you are preserving the intended signal with no outside interference. You will be surprised by how much electrical pollution is in the air once it is removed.
As you can see, the box houses an actual 12AU7 twin triode tube amplifier. It is powered by a DC-DC converter and the output of the tube amp charges the shield to about 50 volts. The tube amp samples the audio signal for it's input section and uses that signal to control the charge to the shield. What is created is a pseudo balanced interconnect, as the shield is effectively neutral relative to both conductors. Relative to the equipment ground, the shield sees half the signal voltage swing. Einstein would ponder the following question, what if the wires do not know that ground is ground? The results are stunning! 99.99% pure Copper twisted pair wires are used for a huge sound stage but still with great inner detail.
