Ethernet Switch UEF

Switch On/Tune In.

Over the years, we’ve developed technologies that redefined what we can expect from our audio systems. Products like the original PowerCell with its patented EM Cell set the bar as the world’s first noncurrent limiting AC power conditioner. We then adapted its EM Cell technology to our Tranquility Base isolation platforms that condition signal while still in a component and power cords with Active EM Cells built-in to function as inline power conditioners. We’ve even applied EM Cells to bias system ground in our Active Ground Block ground conditioners and to our FEQ and Atmosphere ULF Field Generators that control room acoustics without the need for massive traditional room treatments. We’ve continued this decade-long adaption of EM Cell technology to condition the digital signal in an Ethernet Switch for perhaps our most transformational product since the original PowerCell line conditioner. It is no secret that digital sound quality has taken monumental strides forward since the days of “Perfect Sound Forever.” It’s also no secret that many audiophiles, including our Lead Designer, find much to love about the sound of analog playback from LP’s and Tapes. To quote the late great Harry Pearson of the Absolute Sound, “The best way to enjoy digital is to not listen to analog,” and in many respects, we agree. A state-of-the-art analog rig still excels in areas of spacial and holographic realism, as well as a harmonic texture that leaves many digital systems sounding somewhat flat and bleached in comparison.

Solid Billet Aluminum Chassis

With active EM conditioning.

Enter our new Ethernet Switch UEF with UEF and Active EM Cell technology to close the gap between digital playback and state-of-the-art analog tapes and LPs. To accomplish this, we combined all EM Cell and UEF Tech applications and Galileo level chassis construction into a single component. EM Cell and UEF Tech to condition the digital signal? Check. An EM Cell to act as a built-in Tranquility Base? Check. A chassis milled from a solid billet of aluminum like our Galileo Active Ground Block? Check. Use of Carbon Fibre to eliminate the effects of chassis vibration on the signal? Check.

SR Ground Block

This goes to 11.

We’ve even included a direct connection port so you can star ground your new Ethernet Switch UEF to an SR Ground Block for an even lower noise floor. Subjectively in our reference system with an Ethernet Switch UEF we hear a more natural presentation of space and harmonic texture that rivals the best LP and tape playback. We also hear a Jet Black noise floor and dynamics analog rigs cannot match. Perhaps we have finally achieved “Perfect Sound Forever.” The only question is, have we 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.

After just the first minute of listening to one of my test tracks I’ve got a smile on my face and a very rare feeling that I seem to have caught a Big Fish today! During my 20 years of audiophile life with each new component or tweak you can more or less predict what to expect and usually it works out the way you thought it would. That’s not the case today. The changes I hear seem to have added another dimension to music! It seems to be some kind of Higgs boson in my house which caught me completely off guard. The music flows in a continuous stream so effortlessly, coherently and naturally that I find myself not breathing in my favorite parts. New timbre nuances, tonal textures… dynamic decays and bursts become frighteningly realistic! Surprisingly, with the increased amount of information, realism and accordingly emotional involvement I feel more at ease listening to music .

As if before that all musical elements on the canvas were tangled by some kind of invisible web that hindered them somehow, interfered with their natural freedom. SR Router was a real discovery when it comes to which component is the most important in a system. It is N1 device out of all components/tweaks/enhancements for streaming audio I’ve auditioned to date and an absolute must-have.

From the opening seconds, I could feel the atmosphere in the venue. The music had a clarity, presence, and natural feel that, for the first time, made me think there was something worthwhile to streaming music. The sibilance was finally controlled. The soloists were so realistic I could feel something like their personalities in their voices. Musicians were solidly placed in realistic, identifiable positions on the soundstage. Jackson Browne sounded like I had heard him on my reference CD & LP rig. And the applause came from real people in the audience.
