Synergistic Research Foundation XL AC Power Cable

Benefitting from learnings upon the development of our flagship SRX XL cable line, our new Foundation XL power cables deliver notably improved performance above the Foundation SX series and continue to be offered at attractive price points. While the line as a whole can be thought of as an evolution from the Foundation SX, the cable has been rethought holistically, applying the same improvements we’ve made to our new flagship SRX XL cable series. For each cable type, we’ve doubled the 6N pure silver Air Strings to portray music with more immediacy and resolution, improving upon dynamics and transient response in a completely non-fatiguing way. We apply the same SRX XL UEF compound as described above to improve shielding. And finally, the cables are run through the same SRX XL High Voltage Conditioning treatment that we use for our flagship SRX XL cables. With Foundation XL, you’ll notice an improved dynamics and a more natural timbre, all with a reduction in noise floor to keep details of the music smoother and more realistic than its predecessor.

In our journey to design our latest flagship SRX XL series, we developed an entirely new UEF compound to elevate the performance of our previous Matrix Shielding, which further lowers each cable's noise floor while lessening restraints a shield may have on signal transmission. We apply this highest level of SRX XL Matrix Shielding to our new Foundation XL cables for a significant jump in performance over the previous generation Foundation SX. Carbon Fiber UEF Tuning Discs developed for the Foundation SX and Foundation XL series cables further refines and enhances the loom's ability to cancel noise that would otherwise cause high frequencies to sound harsh or fatiguing.

While voicing the Foundation XL, we found that doubling the 99.9995% Pure Silver Airstrings resulted in a cables that are faster and more resolving, adding texture and body while improving dynamics and transient response without adding fatigue.

The new SRX XL High Voltage Conditioning is our most advanced process for treating cables with 1,000,000 volts of electricity at specific frequencies and pulse modulations for long durations, creating a canal in the conductor material and contact points at the molecular level that allows electrons to flow more freely. This new process improves upon the SRX High Voltage Conditioning process by employing new extended duration sweeping frequency plots and advancements to our Tesla Coil, resulting in SRX XL cables to sound even more open and accurate than the cables before them. For Foundation XL, we utilize this exact conditioning process, which we found to contribute to the large performance improvement in this series, bringing the voicing of the Foundation XL closer to that of the SRX XL.

Included with Foundation XL interconnects, speaker cables, and power cables, Carbon Tuning Discs 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.

Synergistic Research is an American high-end audio manufacturer founded in 1992 by Ted Denney in California, recognized for its handcrafted power conditioners, active cables, acoustic treatments, and UEF tuning accessories. The brand rejects the idea of passive connectivity, employing a holistic "total system approach" that relies on active electromagnetic biasing, 1,000,000-volt Quantum Tunneling material treatments, and advanced graphene integration to optimize the electrical and acoustic environment. Their premium product ecosystem—ranging from the single-outlet PowerCell ONE and multi-outlet PowerCell SX line to their widely utilized Purple and Master UEF fuses—is engineered to aggressively lower the system noise floor and maximize dynamic range without introducing traditional current-limiting restrictions.
