Optical Isolation brings even greater silence.

Ethernet noise filter with optical isolation for streamers and network devices

Enjoy the Silence that the LAN iPurifier Pro brings to your network-connected audio system.

The LAN iPurifier Pro utilises Optical Galvanic Isolation technology to effectively isolate and eliminate electrical noise and interference emanating from the router or network switch, ensuring absolute silence and purity of sound.

The LAN iPurifier allows you to experience your music streamers, 4K media boxes, and media streaming PCs exactly as they were designed to perform, free from any interference.

Key Features Explained

Optical Galvanic Isolation

​The optical galvanic isolation technology used by the LAN iPurifier Pro converts incoming LAN signals into optical (light) signals and back again. ​

Jitter Elimination​

The input and output are completely isolated electrically, to stopany noise pass through from the LAN system getting into the stream or DAC.

Signal Regeneration​

After isolating the signal, the LAN iPurifier Pro regenerates the signal using active circuitry to reconstruct the binary data stream, further reducing overall jitter and improving system timing.

Plug and Purify

Whether you're a network novice or an audiophile aficionado, the LAN iPurifier Pro offers a simple, elegant solution for ethernet noise filtration, a feat previously achievable only through complex setups. With a standard LAN input and an optically isolated LAN output, simply connect the LAN iPurifier Pro between your router and network device, positioning it as close to the network device as possible.

Isolation, Regeneration and Elimination. 

Increased system noise significantly amplifies the streamer's jitter, diminishing its performance and resulting in a more digitised sound that lacks the richness and authenticity of true audio reproduction. The LAN iPurifier Pro features Optical Galvanic Isolation to isolate electrical noise and interference, reduce system noise and errors from the router or network switch. Optical Galvanic Isolation technology converts incoming LAN signals into optical (light) signals and back again, accomplishing Signal Regeneration and Jitter Elimination. 

Maximise Performance with iPower

Audiophiles always pursue perfection in their audio systems, and we've ensured there's room for you to upgrade. The LAN iPurifier Pro is powered by USB-C, allowing you to upgrade to iPower2 or iPowerX to enhance overall performance. The iFi iPower2 is an ultra-quiet, ultra-clean audiophile-grade power supply, featuring Active Noise Cancellation II technology to cancel out all incoming EMI and RFI noise, you’ll never feel powerless against noise and graininess again. It is more than 10 times quieter than most audiophile power supplies.

How do I use?

LAN iPurifier Pro

Plug in your LAN iPurifier Pro between your DAC and network router to prevent jitter and EMI reducing the quality of your music. 

SilentPower Reviews


"With the iPower2 the noise disappeared completely with the volume at maximum! That silence is what I expected. I heard the music better! The ZEN Air phono with the addition of the iPower2 goes from being a surprising device for the price, to being surprising for its performance"

The iPower X fever-level transformers introduced this time provide the purest DC power supply equipment. Power supply, iPower X is an AC / DC transformer with extremely low noise. Its small volume is filled with a lot of ifi Audio’s exclusive technologies and fever materials

I believe it is a great everyday carry accessory not only for sensitive IEM/Headphone users but also for beefy headphone amplifier owners who would like to hook up their IEMs to these amps and crank the volume as far as they can. The iEMatch 4.4mm gets the highest recommendation I can give to an audio accessory.

"This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life"
