Foundation SX Power Cords start with 3 x 12 or 3 x 10-gauge copper alloy conductors, more than enough to handle your system’s power needs, including power-hungry amplifiers and line conditioners. We then add 2 x pure silver Air String geometries handmade in our California factory for increased air, image focus, and dynamic impact. Next, we upgraded Foundation SX with brand-new technology first developed for our SRX cable loom and Purple fuses. This new UEF compound delivers a lower noise floor than the original Foundation power cords. Next, we apply a novel long-duration multi-channel high-frequency conditioning process also developed alongside our state-of-the-art cable loom, SRX. All told, Foundation SX upgrades give your system a lower noise floor from which springs a new level of detail, dynamics, and soundstage. No cable at Foundation SX’s price level can match, not even close. But, of course, hearing is believing, so we invite you to experience a massive leap in performance over one of the most popular power cables in SR’s 30-year history.
Originally developed for the flagship SRX series cables, the new high voltage conditioning process applies a sweeping frequency plot for an extended duration. We experimented with dozens of frequencies in different combinations over a prolonged time period before landing on just the right mix. We even built a new Tesla Coil to handle the excess heat generated during long conditioning sessions. Once finalized, the SRX conditioning process created holographic realism and timbrel accuracy far beyond our previous Tesla Coil conditioning protocol.
