iFi's SilentPower journey began at its sister company AMR, where innovations like OptiMains and the world’s first multi-loop noise elimination technology were developed to combat grid noise and DC offset. These technologies now power many iFi products—including the iPower and iPurifier series—bringing high-end audio performance to a wider audience. When existing power solutions failed to meet iFi’s standards, SilentPower was born, sparking a wave of research to solve common Hi-Fi issues caused by electrical noise. Today, SilentPower is a standalone brand, delivering elegant, user-friendly solutions that restore clarity and dynamics to audio systems across industries.
