Synergistic Research
Ethernet Switch UEF MKII
HUGE June 2025 promo!

Switch to Digital like no other

The Synergistic Research Ethernet Switch MkII represents a significant leap forward in network audio technology and digital audio reproduction, incorporating advanced innovations first developed for the flagship Voodoo server (€ 17.495,00) and  PowerCell SRX line conditioner (€ 71.495,00). Inside, the most current EM Cells  (Electromagnetic Cells) for signal filtration are housed, together with SR’s Ultra-Low Frequency (ULF) biasing system, and their latest linear power supply technology, building upon the success of the first-generation UEF Ethernet Switch in a way that dramatically improves every aspect of its performance to achieve unprecedented levels of digital signal purity.

Audibly, these advancements translate to a noticeably expanded soundstage, enhanced resolution, and improved tonal accuracy across the frequency spectrum compared to the original UEF Ethernet Switch. Bass notes gain authority and articulation, while treble extends with airy precision, unveiling musical details that were previously obscured. With the Synergistic Research Ethernet Switch Mk II, Synergistic Research sets another new standard for networked audio.

 

Now with Improved EM Filtration
Digital Signal, Purified

At the heart of the Mk II you will find the next-generation EM Cells, the first re-engineering of their technology since the original patent was sought. Initially developed for the PowerCell SRX to address both power and signal clarity in the digital domain, they selectively filter high-frequency noise from incoming AC power and the digital signal path, eliminating electromagnetic interference (EMI) and switching noise that can degrade audio quality. This results in a significantly lower noise floor compared to the original UEF Ethernet Switch.

 

Ultra Low Frequency Biasing
Shape the Stage

A critical advancement in the Mk II is introducing SR’s magnificent ULF (Ultra Low Frequency) biasing system, a feature absent in the first-generation model. This groundbreaking technology replaces high-frequency noise with harmonics of the Earth’s Schumann Resonance, which pass through the EM Cells unaltered. Unlike the previous switch, which focused solely on first order noise reduction, the Mk II enhances system musicality through this ULF biasing.

Linear Power Supply
Strong and Silent

The Mk II also incorporates SR’s latest linear power supply (LPS) technology, refined during the development of the Voodoo server. This advanced LPS optimizes the DC bias for the EM Cells and the switch itself, unlocking performance levels unattainable from the first-gen UEF Switch. The result is cleaner power delivery and more stable, jitter-free data transmission, even under peak network loads.

 

SR Ground Block
This goes to 11.

Synergistic Research even included a direct banana plug connector so you can star ground your new Ethernet Switch UEF to an SR Ground Block for an even lower noise floor. Subjectively in their reference system with an Ethernet Switch UEF, a more natural presentation of space and harmonic texture that rivals the best LP and tape playback is heard. You also hear a Jet Black noise floor and dynamics analog rigs cannot match. Perhaps SR has finally achieved “Perfect Sound Forever.” The only question is, has SR now surpassed analog playback? Only you can answer this question with a no-risk money-back guarantee. Find out now by calling your authorized Synergistic Research dealer to arrange your in home audition today.

Reviews:
Synergistic Research Ethernet Switch UEF: een bundel voor datapakketten door René van Es @ hifi.nl
“Bij het omschrijven zou ik kunnen gaan praten over een viool met en zonder randje, een slag op een drumkit, de dynamiek daarvan, een individuele stem of een gitaar. Dat gaat met deze switch niet gebeuren. Omdat de positieve werking over een breed spectrum te bemerken is. Het is niet zozeer dat stukje gitaar dat meer spettert, het is het muziekstuk dat prettiger klinkt, niet warmer of niet zozeer detailrijker, gewoon intenser en vloeiender. Dat gebeurt met klassiek, met pop, met jazz, vocaal en instrumentaal.”

World Premiere Review! Synergistic Research Ethernet Switch UEF by Rick Becker @ enjoythemusic.com
“The same song got a lot better. There was more air and a sense of the venue. The sibilants were brought under better (but not complete) control. The musicians were more specifically located, though not pinpointed. The timbre of instruments seemed more correct and there was more tonal color. The soloists became more real, as did the applause. Overall, the music was considerably more enjoyable, as well it should be for the price difference, clearly proving that better Ethernet switches make a significant difference.”

The new Synergistic Research Ethernet Switch UEF from Florida Audio Expo 2022 @ theabsolutesound.com
“We heard a demo of this switch with music playing with the circuitry engaged and not engaged. It was noticeably more lively with the switch engaged. Grounding and better switches seem to be new areas that make a material impact on sound.”

The Final Piece to the Puzzle (searching for an Audiophile Grade Ethernet Switch) by Robert Witrak @ highdeftapetransfers.ca
“It makes a huge stride forward in making digital sound closer to an analog ideal, with a lower noise floor and a much cleaner signal. Honestly, after using the new switch, I wouldn’t want to be without it. This improvement really solidified our mastering chain, and if you utilize an Ethernet Switch, we highly recommend the Synergistic Ethernet Switch together with their excellent cables.”
