The PureTek Audio Alpha is a premium audio-grade network switch engineered with built-in optical isolation to eliminate electromagnetic interference from consumer-grade network devices, such as Wi-Fi routers and modems.

Featuring custom-build PCBs, crafted from the ground up rather than adapted from existing switch boards and specialized SFP modules paired with tailored fiber cables, the Alpha switch sets a new standard for audio performance. These components deliver the high resolution and low-noise benefits of optical isolation without the cold, harsh tonal characteristics often associated with other optically isolated systems.

With the Alpha switch in your setup, you’ll experience an ultra-black background, exceptional extension at both the high and low frequencies, and outstanding resolution that brings out every detail. The result is a vivid sound that unlocks the full potential of your audio system, whether streaming music or playing files from a NAS.

Features:
- Built-in optical isolation
- Aluminum CNC billet chassis
