Foundation SX

Headphone Cables.

Foundation SX headphone cables are handmade in our California factory from core Synergistic Research technologies, including handmade Air String Geometries made or pure 99.9999% Pure Silver conductors in an Air Dielectric for unmatched resolution. We then add UEF Matrix Shielding with a new UEF Compound first developed for our SRX cable loom for a dramatically lower noise floor. Next we include a new Long Duration High Voltage Conditioning Process, initially engineered for our flagship SRX cables, making Foundation SX the most musical and highest resolution headphone cables you can buy. With a full suite of SR Technologies, you hear inner detail and holographic realism that’s never harsh or fatiguing, unlike most pure silver-based cables. And to make voicing them to your headphone rig easy, we include UEF Carbon Tuning discs to strike the perfect balance of musicality and resolution. In short, we’ve created the world’s best headphone cables, and we’re confident you’ll love their sound over ANY headphone cable on the market, regardless of price. So step up, take the Foundation SX Challenge and discover how good your current headphone system actually is.

 

 

UEF Matrix Shield with Graphene

Matrix Shielding

Atmosphere X began when we started exploring ways to improve our UEF Shielding by applying UEF Technology first developed for our BLUE Fuses to Atmosphere Series cables. By placing UEF Tech in a grid pattern on the shields of Atmosphere cables we were able to dramatically lower the noise floor with a surprising increase in musicality or the subjective enjoyment of music. We then began a painstaking double-blind 6-month trial where we would listen to seemingly identical cables marked with random alphanumeric codes to conceal differing patterns of UEF Tech inside each prototype cable and record which options elicited the strongest responses among a control group of listeners. By gauging actual emotional response, we were able to isolate grid patterns that better conveyed the essence of music. We would then build on these patterns to find additional patterns that performed better than the last. In this way, our latest shielding technology is highly evolved from anything we have ever done before with each shield pattern selected for its ability to not only lower a cable’s noise floor but to also convey a greater sense of musical enjoyment. The net result is the most advanced shielding technology we have ever developed with each model in the Atmosphere X Series gaining a special shielding pattern that best compliments the geometries of ALIVE, EXCITE and EUPHORIA.

 

 

Quantum Tunneling

SRX Long Duration High Voltage Conditioning.

After perfecting the most natural-sounding and holographic cables in our history, we set out to take them further with a new high voltage conditioning process that 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.

Adapter cables

FOUNDATION

Built with the same Pure 6N Silver geometries, UEF Matrix Shield, Blue Fuse Treatment and Two-stage Quantum Tunnel Treatment as the foundation headphone cables for best possible performance.

 

 

Synergistic Research

CanJam2019

The first sneak peeks of Synergistic Research Foundation headphone cables were on display at CanJam this year. Audiophiles were blown away by the performance of the soon to be released Foundation headphone cable by a simple A/B tests of Foundation vs. the standard headphone cables provided with Sennheiser HD800s and Mr.Speakers Ether 2 headphones. With two identical sources, amps and headphones on display, customers could also easily compare a system with a full treatment of Synergistic Research Technology vs. one without. See the great reactions we received!
