Foundation SX Power Cable


Foundation SX Power Cords start with 3 x 12 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 competitor's 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.

MSRP: $599 / 5FT - 15A ($60 per additional foot)
