Headphone cables

FOUNDATION

FOUNDATION Series headphone cables are handmade in our California factory with cutting edge Synergistic Research technologies including Air String Geometries with pure 99.9999% Silver. Another trickle-down technology is our UEF Matrix Shielding that dramatically lowers your perceived noise floor. With a full suite of SR Technologies, you hear resolution and holographic realism that’s never harsh or fatiguing, unlike most pure silver-based cables. In pulling all the stops, we applied a new High Voltage Treatment Process first developed for our Galileo SX World’s Reference Audio Cables. In short, we’ve created the worlds best headphone cables, and we’re confident you’ll love their sound over ANY headphone cable on the market regardless of price. That’s why we’re selling them with a no-risk money-back guarantee from participating SR Dealers. So whether you’ve got a state-of-the-art headphone rig including upgraded headphone cables or if you’re a cable skeptic, FOUNDATION Series headphone cables will prove Synergistic Research is building the highest performance headphone cables on the planet. Now is the time to step up and take the FOUNDATION Challenge and find out just how good your current headphone system sounds with Synergistic Research.

UEF Matrix Shield with Graphene

Matrix shielding.

Learn more about UEF Matrix Shield

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.

Build Notes:

  • 12 point-to-point hand soldered connections
  • Atmosphere Level 2 UEF 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: 2 hours
  • Quantum Tunneling: Post Production process, 1 million volts are passed through finished cable providing a “canal” that allows electrons to pass more freely through conductor material and connections
  • Secondary UEF Blue Treatment originally developed for SR Blue Fuses
  • 5 day Burn-in: 2 step process
  • Handmade in our California factory

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!
