The Purist Audio Design Power Extension Box has a chassis from a special aluminum alloy with dampening that limits mechanical vibration. PAD uses proprietary passive filtering to protect the sound and not interfere with it. In addition, resonator tubes are utilized and these are tuned to a frequency of 50 or 60 Hz depending on country. They help to passively filter out noises generated by electricity that is flowing through the outlet and does not limit voltage or current. The internal wiring is the same technology used in their upper line power cords connectors are carefully selected and matched Furutech outlets and an IEC inlet.
