Ifi Audio LAN iPurifier Pro
LAN iPurifier Pro is an advanced development of LAN iSilencer. It is an Ethernet noise filter with optical isolation that eliminates electrical noise and interference from network routers.
It improves the sound quality of music streamers, 4K media boxes and streaming PCs by isolating and regenerating signals, minimising jitter and system noise.
I highly recommend upgrading with iPower X for better power.
