USB noise filter and ground loop protection for crystal-clear sound

The iFi noise Suppressor addresses common USB noise and ground loop issues. It breaks noisy ground connections and allows injection of clean external power (with optional iPower 5V), improving dynamic contrast, warmth, and resolution. Suitable for home and professional audio systems, the Suppressor reduces USB noise by 100x compared to a typical port thanks to Active Noise Cancellation and USB3.0 technology.

• Active Noise Cancellation: improves dynamics and warmth
• USB3.0: gold-plated connectors, backward compatible with USB2.0
