I own Bliss Hifi, a high-end audio boutique and authorized Synergistic Research dealer, and these Atmosphere SX Euphoria XLR Interconnects are being listed as a consignment sale on behalf of my client for whom I am selling his entire system. He is the sole owner and purchased these new from Bliss Hifi. They are in like new cosmetic condition and perfect working order.

These interconnects include the upgraded Synergistic Research SR20 XLR connectors, a factory upgrade that replaces the standard Neutrik connectors with SR’s proprietary high-purity, high-conductivity, low-mass silver XLR connectors with Teflon dielectric. These are the same connectors found on SR’s flagship Galileo and SRX cable lines, and they maximize contact area for more refined detail, greater information transfer, and lower noise. It’s a meaningful performance upgrade that elevates these cables closer to flagship territory. The cables also come with both the Gold and Silver Galileo SX Tuning Bullets and ship in their original SR packaging.

A ground plug is not included as SR stopped supporting and including them with the cables in early 2025. If desired, one can be ordered from SR for $25+shipping.

The Atmosphere SX Euphoria is SR’s most advanced Atmosphere-level interconnect, and these XLR versions are the most complex in the lineup with four separate runs of Tricon 5th Generation Silver Matrix geometries plus eight pure silver Air Strings in an air dielectric, all handmade in SR’s California factory. The sound is expansive, detailed, and musically engaging in a way that rewards long listening sessions. With the ability to voice the presentation via the Gold and Silver Tuning Bullets, plus grounding the shields to an SR Ground Block, these cables offer a level of tunability and system integration that no other cable brand provides. As an authorized SR dealer, I can say these are among the most versatile and rewarding interconnects in the Synergistic lineup.

Check my stellar feedback on popular marketplaces and buy with confidence. This listing includes free insured shipping across the CONUS. As this is a passthrough sale that I am brokering on behalf of my client, I can only accept payments via PayPal F&F, Venmo Gift, or personal check, but this also gives you the opportunity to attain this at my lowest possible price.

Happy to answer any questions. Thanks for your consideration.

More about the unit: The Synergistic Research Atmosphere SX Euphoria (Level 3) XLR Interconnects represent the pinnacle of SR’s Atmosphere SX cable series, incorporating technologies originally developed for the flagship SRX loom and applying them at a more accessible price point. Each pair consists of four separate runs of 5th Generation Tricon Silver Matrix cables with monocrystal conductors, a separate ground conductor isolated from the shield, Teflon dielectric, and Ground Plane Technology shielding, with each cable individually listened to for signal direction before assembly. Running alongside those are eight 99.9999% pure monocrystal silver Air String conductors in a sealed air dielectric with UEF Ground Plane Technology shielding, double the Air String count of the Excite SX level below. A Level 3 OTSP UEF Cell provides three-channel filtration for ground, signal, and shield simultaneously, housed within a carbon fiber enclosure containing precious metal foils with Teflon and Japanese Silk dielectrics for the lowest noise floor and most expansive soundstage in the Atmosphere SX range.

Exclusively developed for the Atmosphere SX series, carbon fiber UEF Tuning Discs are placed at strategic points along the cable’s shield and inside the connectors to lower the noise floor and increase resolution without introducing harshness. The entire cable assembly receives SR’s Long Duration High Frequency Conditioning Process, originally developed for the SRX cable loom, and Level 4 UEF Matrix Shielding applies two different UEF coatings with graphene directly to the UEF Cell, connectors, cabling, and ground for a significantly reduced noise floor. The Euphoria SX comes equipped with both Gold and Silver Galileo SX Tuning Bullets, allowing the listener to voice the cables on a component-by-component basis: Gold delivers greater warmth and liquidity, while Silver offers maximum detail and pinpoint spatial focus. For further performance gains, the cable’s shields can be grounded to a wall outlet via the included SR ground plug or to an optional Synergistic Research Ground Block for a dramatic lowering of the system noise floor with benefits including deeper bass, a more holographic sound field, smoother high-frequency extension, and increased tonal density.
