Foundation SX

Digital Interconnects.


Foundation SX Digital cables start with geometries and materials like pure silver plus Teflon and air dielectrics that are perfect for transferring digital signals without loss or jitter. We then apply technology initially developed to elevate our cost-no-object SRX cable loom for maximum resolution paired with musicality, so you enjoy long listening sessions without fatigue. Next, SRX UEF compound is applied in a grid pattern to the shield of Foundation SX digital cables to reject noise while expanding your system’s holographic potential in a not-so-subtle way. Lastly, we hit each digital cable with a five day multi-step High Current Long Duration Conditioning Process initially developed for the SRX cable loom. The inclusion of cutting-edge SRX technology gives Foundation higher resolution with a lower noise floor plus musicality that was not possible with the original Foundation Digital Cables. And to voice Foundation SX Cables to blend perfectly with your system and personal tastes, we include UEF Carbon Tuning Discs so you can custom tailor the sound of your cable to compliment your stereo. For improved image focus and clarity, apply a Purple Tuning Disc or select a Gold Tuning Disc when greater warmth and liquidity are needed. Of course, you can also run Foundation SX Digital straight without the included Tuning Discs. The choice is yours.

    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. 



    Foundation SX Digital Interconnect Specifications:

    Global MSRP
    US $449/1m  - SPDIF / AES/EBU ($110 per addl .5meter)


    1 each RCA, 2 each XLR Silver Matrix Conductor:

    • Silver Matrix Signal conductor: Monocrystal conductors with copper core
    • Dielectric: Solid Polytetrafluoroethylene (PTFE)
    • Maximum Frequency: 12.4 Ghz
    • Geometry: SPDIF single run / AES/EBU double run

    RCA and XLR Connectors:

    • Silver Teflon SR 20 SPDIF or Neutrik NC3FX-BAG, NC3MX-BAG, AES/EBU connectors

    Build Notes:

    • 4 (RCA) 6 (XLR) point-to-point hand soldered connections
    • SRX Matrix Shielding: UEF coating with Graphene is applied directly to connectors significantly reducing the noise floor and allowing a purer signal to transfer with less grain providing more warmth and detail
    • Silver Solder: 4%
    • Hand build time: 1.25 hours
    • SRX Quantum Tunneling: After the cable is completely assembled all connections and cabling are treated with 1,000,000 volts of electricity at specific frequencies and pulse modulations, creating a canal in the conductor material and contact points at the molecular level that allows electrons to flow more freely. This allows the maximum amount of low level information through the conductors and provides for the highest amount of realism in your music
    • Secondary UEF Blue Treatment originally developed for SR Blue Fuses
    • 5 day Burn-in: 2 step process
    • Hand crafted in our California factory




    Atmosphere acoustic field generator

    Supercharge your cables.

    Imagine listening to Charlie Parker at Birdland, then walk into Carnegie Hall to be seated at the best place in the house. This is can all be possible in your listening room by adding Atmosphere. No other product allows you to tailor the size and depth of your soundstage with stunning realism to accurately match the type of music you are listening to. Atmosphere is a multi-wave RF generator that has the ability to change your listening environment. Simply place it your room, turn it on, and let yourself be amazed.



    Carbon Performance Elevators

    Elevate your system.

    UEF Carbon Elevators lift your cables from the floor as they uplift fundamental aspects of system performance, including low-frequency weight and control, mid-range clarity, and high-frequency extension. Perhaps most dramatic is the effect on your system’s ability to portray soundstage scale with improvements in front to back, side to side, and verticle image placement, all with a greater sense of the sound field wrapping around your listening position. Our first cable elevators were made from aluminum after extensive double-blind listening tests, where aluminum exhibited superior sound quality compared to materials like plexiglass, wood, and ceramic. The one material we did not test was Carbon Fiber due to its difficulty to cut and fabricate. Fast forward two years, and we have perfected the use of carbon fiber in SR products, including our state-of-the-art SRX cable loom, Galileo Active Ground Block, Active Ethernet Switch, and MiG SX footers. So we built a set of carbon fiber elevators and compared them to our Aluminum cable risers. We found the same improvements as all SR products using carbon fiber, namely, increased resolution, inner detail, and clarity. The included HFT’s (Red Dot visible in photographs) use a new UEF compound first developed for SRX speaker cables and Purple fuses enteract with your cables EM fields for life like soundstage scale with enhanced dynamics and high-frequency extension. Of course, cable elevators are a controversial upgrade for many, so we make it easy to try a set in your system risk-free. Audition in your system, and if you disagree, return them to your dealer for a full refund.
