Product Description: 

The Atmosphere X EUPHORIA is hand-built in Synergistic Research’s California factory, featuring 2 × 4th Generation Tricon and 2 × 99.9999% pure silver handmade AirString RCA connectors, alongside 2 × 4th Generation Tricon Geometries and 4 × 99.9999% pure silver handmade AirString XLR geometries. Performance is elevated with the same UEF Technology that makes SR BLUE Fuses a breakthrough in musicality. Additional design innovations include a passive UEF Filter in a carbon-fiber housing, the Quantum Tunneling 1,000,000-volt conditioning process, Graphene Shielding for the quietest Atmosphere phono cable, and Red and Blue UEF Tuning Modules, allowing users to choose between detailed or liquid sonic balance entirely outside the signal path. Further enhancements include multi-layer mechanical resonance rejection for improved clarity and detail, as well as Ground Plane coupling that redirects shield noise away from the phono preamplifier, sending RF and EMI safely to wall ground via the supplied connection.

UEF Matrix Shield with Graphene Matrix Shielding

The Atmosphere X Series originally explored ways to improve UEF Shielding by positioning UEF Tech at key grid points along cable shields—a method now known as Matrix Shielding. This design lowers the noise floor and enhances clarity. Atmosphere SX refines the concept further by incorporating newly developed Carbon Fibre UEF Tuning Discs, which improve the loom’s ability to cancel noise that could otherwise make high frequencies sound fatiguing. The result is greater resolution, a more holographic soundstage, and improved musicality.

Quantum Tunneling SRX Long Duration High Voltage Conditioning

After perfecting highly natural and holographic cables, Synergistic Research introduced a new high-voltage conditioning process for Atmosphere SX. This process applies a sweeping frequency plot for an extended duration. They experimented with dozens of frequencies in different combinations over a prolonged time period before landing on just the right mix. They 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. conditioning sessions. The final SRX conditioning process delivers exceptional timbral accuracy, holographic realism, and three-dimensional presence, surpassing previous Tesla Coil protocols.

Gold SX Tuning Bullet—Redefining Refinement

Synergistic Research has completely redesigned and re-voiced its Galileo Tuning Circuits, incorporating technology developed for the ultra-resolution, highly musical Galileo SX cable line. The updated Silver Bullets now deliver increased detail while adding greater warmth compared to the previous Galileo Silver Bullets. The Gold Bullets enhance musicality even further, offering liquid smoothness, a touch more air, and improved detail. For optimal results, it is recommended that any Synergistic Research cable first settle into the system for 72 to 96 hours without removal or handling, and without Gold or Silver Bullets attached. Listeners should then audition with the Gold Bullets first, followed by the Silver, selecting the option that best enhances musical enjoyment in their system.

Atmosphere Excite SX provides the Gold SX Tuning module while Atmosphere Euphoria SX  comes equipped with both the Gold and Silver SX Tuning Modules.

Gold Tuning Module’s Sonic Characteristics:

• Greater Musicality
• Greater Liquid Smoothness
• Air and Detail

Silver Tuning Module’s Sonic Characteristics:

• Greater Air and Detail
• Musicality
• Liquid Smoothness

UEF Cell—Filter Noise, Feel the Music

Atmosphere X Euphoria interconnects and speaker cables integrate the same Patent-Pending UEF Cell technology used in our Flagship Galileo UEF series. Within Carbon Fiber enclosures, these Unified Energy Field Cells are comprised of precious metal foils with Teflon and Japanese Silk dielectrics. UEF components, including Graphene, are applied directly to the signal and shields, lowering the noise floor and allowing the musical information to move through the cable unimpeded by spurious interference and signal reflections. The result is music that is uncompressed, visceral, and live.
