From iFi Audio

When used for audio, Ethernet LAN interfaces are inherently ‘noisy’. iFi’s LAN iSilencer removes electrical noise that distorts the audio signal to unleash the connected equipment’s full, sonic potential.

Complexities of Ethernet

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, completely ideal on paper. In practice, Ethernet 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.

Setting Your Sound Free

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, minimizes 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.

Skeptical consumer

I bought this on a whim.. curiosity. Always looking for improvements in my digital streaming set up. Honestly due to its "budget" type price I figured it might just be another snake oil product looking for a small cash grab. Fortunately though this little passive device comes correct. A positive improvement sticking this unit into the rear of my Primare Prisma streamer. It's a keeper. Tried it on my TV as well...also a noticeable improvement in sound coming from my TV thru my RME Dac. So I'll be ordering a 2nd one...TV & Streamer.
Bloom Audio was great to order from..shipping is fast, arrived 2 days later from 5 states away.
