Foundation SX 

Power Cables

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.

UEF Matrix Shield with Graphene

Matrix shielding.

The previous Atmosphere X Series Cables started as an experiment to explore ways of improving UEF Shielding by placing UEF Tech at strategic grid points on the shields of Atmosphere cables, now called Matrix Shielding. Matrix Shielding arranges UEF elements on a grid pattern of the cable shield to lower its noise floor. Atmosphere SX refines Matrix Shielding further by using new Carbon Fibre UEF Tuning Discs developed expressly for Atmosphere SX to enhance the loom's ability to cancel noise that would otherwise cause high frequencies to sound harsh or fatiguing. As a result of our ongoing research into UEF Shielding, we have pushed the resolution envelope when voicing Atmosphere SX by developing new Carbon Fibre UEF Tuning Discs for a more holographic sound with enhanced resolution and musicality.

Included Carbon Tuning Discs

Tune to perfection.

Included with SR30 interconnects, speaker cables, and power cables, Carbon Tuning Discs ($199.95 MSRP) are a spinoff of our new Atmosphere SX Loom where they are placed inside cables at key locations and are instrumental in creating the SX sound. Based on our patented UEF technology, each disc gets treated with a unique UEF compound that interacts with EM fields wherever you place them in your system or on cables to improve sound quality. The conductive carbon fiber material of the disc enhances the interaction between the UEF compound and the surrounding EM fields where it is placed.  The Gold- Carbon Tuning Discs flesh out rich harmonics combined with a clarifying effect in the sound field for a more lifelike and holographic presentation. Purple- Carbon Tuning Discs get treated with a UEF compound that enhances clarity and extension in the soundstage even beyond Gold.

Quantum Tunneling

SRX Long Duration High Voltage Conditioning.

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.
