Philistine-
Phil said it much better than I could... next application is 3M mounting taped over the spare receptical of the AV duplex. You can expect the same effect he had at the same location. After that, pick up two more and add it to the AC and IEC shell of the main power cord. A good tip is to remove the crystal from inside the box, pour it inside the Wattgate-style AC and IEC shell for an additional 10-15% improvement. From there, you can add them to every power cord that allows. You can also use them inside components - we recommend them over the transformer(s) or choke(s), other folks tell us they place it directly on the processor chips of their digital players and receive supurb results. Each AC addition will yield additional benefits, and each application does something different. Circuit breaker deals with soundstage size, receptacle intensifies the sound quality, and the AC/IEC provides a purer tone to the musical presentation. The upcoming wire-in increases detail and further enhances tonal reproduction.
Enjoy!
