The Magic Reference II Special Edition Power cord is unique by filtering both high/low frequency noises as well as noises in the middle frequency range without any interference from the most desired levels of power. The "PureAC module" also filters the most undesirable DC component interference (that may occur) in an AC source. The final touch added to the Magic Reference II Special Edition Power cord is its ability to distinguish and filter all low amplitude noise to deliver the most uncolored and articulate power cord available.
