Synergistic Research Atmosphere SX Euphoria Speaker Cables

Euphoria SX is a closely scaled-down expression of SR’s flagship Galileo SX cables, making it the most complex speaker cable in the Atmosphere SX lineup.

EUPHORIA SX speaker cables start with Alive SX’s twin Silver Matrix geometries in parallel, plus Excite SX’s two hand-made pure silver Air Strings. We then added two additional pure silver Air Strings plus two Silver Matrix 5th-Gen Tricon geometries for a total of eight parallel speaker cable geometries per speaker wire run, or sixteen total for the pair. The inclusion of four Air Strings and two 5th Gen-Tricon’s per channel means you hear increased detail in a larger and more expansive sound field. Euphoria SX is a closely scaled-down expression of our flagship Galileo SX speaker cables, making it the most complex speaker cable in the Atmosphere SX lineup with 4 x 2nd Gen- High Current Silver Matrix Geometries, 4 x 5th Gen-Tricon Geometries, 4 x 99.999% Pure Silver Air String geometries hand made in our California factory. Exclusive to Euphoria SX is the inclusion of our patented SR Ground Plane technology first developed for PowerCell line conditioners and later adapted for cable applications in our Galileo SX Series Cables and SRX power cords to deliver a lower noise floor with an impressive holographic scale. Expressly developed for the Atmosphere SX loom are small Carbon Fibre UEF Tuning Discs placed along strategic points on the cable’s shield and inside connectors to lower the noise floor and increase resolution without harshness. Euphoria SX further builds on Excite SX’s system matching versatility with the addition of a Silver Galileo UEF Tuning Bullit for more detailed sound with air, to the included Galileo SX Gold UEF Tuning bullet’s warmth and liquidity. Listen to EUPHORIA speaker cables in your system with the Silver and then with the Gold filter and select the option that creates music in your system. Lastly, EUPHORIA’s 16 cable geometries are individually isolated from mechanical resonance and vibrational feedback to enhance clarity in the sound field. User Tip: very few systems, if any, benefits from all one color or another. Most systems will sound best with a majority of either Gold or Silver bullets, but with a component or two that perform best with the opposite color. Gallio SX Gold Tuning Bullets capture warmer sound with liquidity over pinpoint spatial detail. Galileo SX Silver Tuning Bullets are detailed and dynamic with a pinpoint focus at the expense of liquidity. All systems benefit from a majority of either Gold or Silver with a component or two that will sound best with the other option. Tuning individual cables with Galileo SX Tuning Bullets achieves the best sound characteristics of both Gold and Silver with a bespoke balance unique to your system.

SR BoFa Banana and SR Silver Spade Connectors:
Build Notes:
  • 36 point-to-point hand soldered connections
  • Individual EXP Isolated cable geometries for improved vibrational isolation of each geometry
  • Atmosphere SX UEF 4 Treatment: 2 different UEF coatings with Graphene are applied to UEF Cell, connectors and cabling and ground significantly reducing the noise floor and allowing a purer signal to transfer with less grain providing more warmth and detail. The conductors and ground plane and UEF Cell also benefit from dampening effect that UEF provides
  • 1 Termination for Atmosphere Tuning Module (Red) and (Blue)
  • Silver Solder: 4%
  • Hand build time: 5.5 hours
  • SRX Long Duration 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
