Ethernet Switch UEF MkII

A Switch to Digital Like No Other

The Synergistic Research Ethernet Switch Mk II represents a significant leap forward in network audio technology and digital audio reproduction, incorporating advanced innovations first developed for Synergistic Research's flagship Voodoo server and $65,000 PowerCell SRX line conditioner. Inside is housed the most current Electromagnetic Cells for signal filtration, Ultra-Low Frequency (ULF) biasing system, and latest linear power supply technology, building upon the success of the first-generation UEF Ethernet Switch in such 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, another new standard has been set for networked audio.

Now with Improved EM Filtration, Digital Signal, Purified

At the heart of the Mk II are  next-generation Electromagnetic Cells (EM Cells), the first reengineering of their technology since Synergistic Research's original patent. 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 the 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 Synergistic Research's 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 Synergistic Research'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 one goes to 11

Synergistic Research has 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 Synergistic's reference system with an Ethernet Switch UEF a more natural presentation of space and harmonic texture was heard that rivals the best LP and tape playback. A Jet Black noise floor and dynamics was heard that analog rigs cannot match. Perhaps SR has finally achieved “Perfect Sound Forever.” The only question is, has SR surpassed analog playback? Only you can answer this question.
