Synergistic Research Ethernet Switch MKII UEF

Key Features: 

• Active EM Cell and UEF Signal Conditioning – Actively refines digital data for greater purity, reduced noise, and a more analog-like musical presentation.
• Solid Billet Aluminum and Carbon Fiber Chassis – Minimizes vibration and resonance to preserve signal integrity and enhance sonic realism.
• Integrated Tranquility Base Circuit – Functions as a built-in isolation platform to further lower the noise floor and increase resolution.
• Ground Block Connectivity – Provides a direct link to Synergistic Research Ground Blocks for star grounding and even deeper black backgrounds.
• Galileo-Level Engineering – Combines Synergistic Research’s flagship design standards and breakthrough technologies to deliver unprecedented digital performance.

Product Description: 

Throughout its history, Synergistic Research has pioneered technologies that have continually redefined what’s possible in high-end audio performance. The introduction of the original PowerCell, featuring the world’s first non–current-limiting EM Cell, established a new benchmark in AC power conditioning. This breakthrough technology later evolved into the Tranquility Base isolation platforms, which actively condition signal within a component, and into power cords equipped with built-in Active EM Cells, functioning as inline power conditioners.

The same EM Cell innovation has since been integrated into Active Ground Block systems for grounding optimization and into FEQ and Atmosphere ULF Field Generators that manage room acoustics without conventional treatments. Now, Synergistic Research continues this legacy by applying EM Cell technology to digital signal conditioning within an Ethernet switch—arguably the company’s most transformative advancement since the original PowerCell.

While digital audio has made tremendous progress since the early days of “Perfect Sound Forever,” many still cherish the organic warmth and spatial realism of analog playback. As the late Harry Pearson once said, “The best way to enjoy digital is to not listen to analog.” In that spirit, Synergistic Research’s latest developments aim to close the gap—bringing digital reproduction closer than ever to the depth, texture, and dimensionality of true analog sound.

Solid Billet Aluminum Chassis with Active EM Conditioning

The Synergistic Research Ethernet Switch UEF was engineered to bridge the final gap between digital playback and the rich, immersive realism of reference-level analog. This breakthrough component unites the company’s most advanced innovations—UEF and Active EM Cell technologies—with the elite construction standards of the Galileo series.

Inside, EM Cell and UEF circuits actively condition the digital signal for greater purity and musicality, while a dedicated EM Cell functions as an integrated Tranquility Base to reduce noise and enhance resolution. The chassis, precision-milled from a solid billet of aluminum and reinforced with carbon fiber, minimizes vibration and resonance, preserving signal integrity at every level. The result is an Ethernet switch that transforms networked audio into a more natural, analog-like experience—fluid, dimensional, and profoundly lifelike.

SR Ground Block—This Goes to 11.

The Synergistic Research Ethernet Switch UEF includes a dedicated port for direct connection to an SR Ground Block (sold separately), allowing for star grounding and an even lower system noise floor. When integrated into a reference system, it delivers a presentation of space, tone, and harmonic texture that evokes the finest qualities of LP and tape playback—while offering jet-black silence and dynamic range beyond what analog typically achieves.

With the Ethernet Switch UEF, Synergistic Research may have come closer than ever to realizing the promise of “Perfect Sound Forever.” The real question is whether it has finally surpassed analog altogether. Listeners are invited to experience the difference firsthand through a no-risk, in-home audition available from authorized Synergistic Research dealers.
