Ethernet Switch UEF Mk II
US MSRP $2,895 | Global MSRP $3,195
A major step forward in networked audio, the Mk II brings innovations first developed for the flagship Voodoo server and the $65,000 PowerCell SRX line conditioner to an Ethernet switch. Current-generation Electromagnetic Cells, a new Ultra-Low-Frequency (ULF) biasing system, and the latest linear power supply deliver a wider soundstage, higher resolution, and more accurate tonal balance than the original UEF Ethernet Switch — with bass that gains authority and treble that extends with airy precision.
- Next-generation EM Cells for signal filtration
- New ULF biasing system (not found in the first-generation switch)
- Latest linear power supply technology
- Expanded soundstage, enhanced resolution, improved tonal accuracy

Atmosphere SX Ethernet Cable (1m)
MSRP $995
Built for hours of fatigue-free listening with startling holographic realism. Proprietary UEF Graphene Shielding and a new Matrix Shielding compound deliver the lowest possible noise floor, while conductor alloys proven in double-blind testing provide dramatic high-frequency extension that stays musical. Conditioned with technology from the SRX Cable Series, Atmosphere SX surpasses the previous Ethernet Active SE with lower noise, higher resolution, and greater musical engagement.
Ethernet UEF Performance Enhancer
MSRP $295
A plug-in UEF filter that lowers your system’s noise floor so you hear more music with greater clarity and sweeter highs. Built on a UEF Compound first developed for the flagship SRX cable loom, a single Performance Enhancer brings deeper, tighter bass and an expanded soundstage — and a second one magnifies the effect.
