What customers say
Audiophiles overwhelmingly praise the Synergistic Research Ethernet Switch UEF MK.II for its transformative impact on digital streaming quality. Users consistently report significant sonic upgrades, noting a dramatic expansion of the soundstage, superior micro-detail retrieval, and faster transient response. This performance is attributed to proprietary technology that lowers the noise floor, yielding a blacker background and a more relaxed, analog presentation free from digital harshness. While the exceptional performance is lauded as essential for state-of-the-art playback, the extremely high price point creates significant polarization regarding its value proposition. For dedicated users prioritizing ultimate sonic purity, the consensus is that this switch delivers top-tier results.
Know before you buy
The ULF biasing system works by replacing high-frequency digital noise with Earth's natural resonance. This process helps lower the noise floor, which allows for a more expansive soundstage and greater clarity in your music.
No, this is an unmanaged, plug-and-play Layer 2 switch. It is designed to be installed directly into your network without the need for complex setup or software management.
No, the Ethernet Switch UEF Mk.II does not support PoE. It is specifically engineered for high-fidelity audio performance and does not provide power to connected network devices.
The Foundation SX power cable is included to ensure the switch receives clean, stable power from your wall outlet. Using a high-quality cable helps maintain the integrity of the internal linear power supply, which is critical for minimizing signal interference.
Yes, the unit features a fanless design. It operates silently, ensuring there is no mechanical noise or vibration that could interfere with your listening environment.
While it will function for standard networking, it is purpose-built for high-end audio streaming. Its design prioritizes signal purity and noise reduction over features like Jumbo Frame support, which are typically used for high-speed data throughput.
