Synergistic Research Element Tungsten AC Power Cord

Element Tungsten was the first power cord in the Element Series to feature tungsten in the signal path.  It is the first power cord in the world to use pure tungsten as a conductor. Tungsten has unique sonic characteristics.  To summarize, during our 6-month double-blind listening test, we discovered Tungsten to be the most holographic sounding of all elements tested.  Listening  revealed exceptional high frequency extension and note decay that comes from a lower perceived noise floor. Perhaps this is why  tungsten’s sound is so holographic. In fact, many people feel the real magic starts with Tungsten due to its amazing portrayal of live music, presented in realistic space and scale, with note decay that is closer to a live event than any other single element.
