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 our flagship Voodoo server and $65,000 PowerCell SRX line conditioner. Inside, we now house our most current Electromagnetic Cells for signal filtration, our Ultra-Low Frequency (ULF) biasing system, and our latest linear power supply technology, building upon the success of our 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, we set another new standard for networked audio.

Key Features

Improved EM Filtration

At the heart of the Mk II are our next-generation Electromagnetic Cells (EM Cells), the first reengineering of their technology since we sought our original patent. Initially developed for our 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 our original UEF Ethernet Switch.

Now with Ultra Low Frequency Biasing

A critical advancement in the Mk II is introducing our 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 our previous switch, which focused solely on first order noise reduction, the Mk II enhances system musicality through this ULF Biasing.

Linear Power Supply

The Mk II also incorporates our 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.

Direct Connection Port

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.”
