Synergistic Research Atmosphere SX Excite Speaker Cables Product Description:
Excite SX expands on the dual Silver Matrix geometries found in Alive SX by introducing two additional hand-crafted Air String geometries made from ultra-pure 6-9’s silver for each speaker cable. This results in four distinct geometries per cable run, or eight total per stereo pair. The addition of Air Strings brings a noticeable increase in detail, spaciousness, and three-dimensional realism. To further elevate performance, the cable undergoes the same High-Frequency Long Duration Conditioning Process originally developed for the reference-level SRX series. This is the very process behind the acclaimed Purple Fuses, recognized as the highest-performing audio fuses available. For system matching, Excite SX includes two Galileo SX Gold UEF Tuning Bullets, giving listeners the option to fine-tune their system’s sound. Simply compare playback with and without the tuning bullets and select the presentation that best suits your musical taste.
UEF Matrix Shield with Graphene Matrix Shielding
Earlier Atmosphere X Series Cables pioneered the use of UEF Tech at carefully chosen grid points along the shielding, a method now known as Matrix Shielding. This design lowers the noise floor by dispersing UEF elements across a shield grid. Atmosphere SX builds on this by incorporating new Carbon Fibre UEF Tuning Discs, engineered specifically for the series, which enhance noise cancellation and prevent high frequencies from sounding edgy or fatiguing. The result is greater resolution, holographic imaging, and natural musicality, all thanks to continued advancements in UEF Shielding.
After perfecting the most lifelike and immersive cables in the line, the team pushed further with a newly developed high-voltage conditioning process. This technique uses an extended sweep of multiple frequencies applied over long durations, refined through extensive testing of combinations until the ideal balance was achieved. A new Tesla Coil was even engineered to withstand the heat from these extended sessions. The final SRX conditioning method delivers an unprecedented sense of realism, tonal accuracy, and three-dimensional presence, setting a new benchmark beyond previous conditioning protocols.
UEF Cell and Blue Tuning Bullets
EUPHORIA SX speaker and interconnect cables utilize Patent-Pending UEF Cell technology from the Galileo UEF series. These cells, housed in Carbon Fibre enclosures, combine precious metal foils with Teflon and Japanese Silk dielectrics. UEF elements, including Graphene, are applied directly to the signal and shield paths, reducing noise and preventing interference. The result is uncompressed, visceral, and lifelike musical reproduction.
Gold and Silver SX Tuning Bullets
Galileo Tuning Circuits have been fully re-engineered for the ultra-resolution EUPHORIA SX cables. Silver Bullets now provide increased detail with added warmth, while Gold Bullets deliver enhanced musicality, liquidity, and air. For optimal performance, allow cables to settle in the system for 72–96 hours without handling or bullets attached. Then audition Gold and Silver bullets to determine which setting produces the most musical results. Atmosphere Excite SX comes with the Gold UEF Tuning module, while EUPHORIA SX includes both Gold and Silver modules for maximum tuning flexibility.
