iFi LAN iSilencer

In recent years, more and more music lovers have taken to streaming music as their primary audio source. These streamers are often connected to audio gear via network routers. There are pros and cons to this. Ethernet interfaces can pass hi-res audio data at maximum resolution and, allow bit-perfect conveyance of the original source data – which is ideal, on paper. In practice, LAN is a complex, multi-purpose computer interface – not one that was created specifically for audio. It is susceptible to electrical noise, not least from the router’s power supply, which can adversely affect sound quality.

iFi makes several devices that enhance audio quality. Two of the most popular are the iSilencer+ and iDefender+. Joining that illustrious family is the new LAN iSilencer, that boasts premium galvanic isolation technology, where electrical circuits are separated to eliminate stray currents.

The LAN iSilencer features Gigabit Ethernet support, with no speed restrictions. It is constructed using a shielded socket and plug with integral ground connections, that blocks external interference, minimises packet loss and ensures stable signal transmission.

Whilst isolating and removing system noise, the LAN iSIlencer reduces the overall jitter in the system – a form of digital distortion that leads to timing errors and results in cold, harsh sound. It also re-balances the signal via iFi’s REbalance technology, ensuring that the digital signal received by the streamer is identical to the original source.

The LAN iSilencer can be connected to a router, network switch or ethernet wall socket. No power source is needed. The precise effect of the LAN iSilencer on sound quality varies from system to system; typically, one can expect to hear more clarity, greater dynamic extension and sharper leading edges, making the music sound more vivid and open.
