Ifi LAN iPurifier Pro – Ethernet Filter with Optical Isolation

Pure Network Connectivity for High-Fidelity Audio

The iFi LAN iPurifier Pro represents one of the most advanced innovations in network signal treatment for professional and high-end audio applications. Perfect for network streamers, DACs, and AV systems, this device acts as a digital purifier, eliminating interference from your LAN and regenerating the signal with absolute precision.

Galvanic Optical Isolation – Drawing the Line Against Noise

At the heart of the LAN iPurifier Pro is a sophisticated galvanic isolation system via optical conversion. The concept is simple yet powerful: the incoming electrical signal is converted into light, passed through an optical filter, and only then converted back into electricity. This breaks all direct electrical paths between source and destination, preventing high-frequency noise, ground loops, or EMI/RFI spikes from affecting sound quality.

About iFi Audio

iFi Audio is a cutting-edge British brand specialized in high-performance DACs, amplifiers, and accessories for discerning audiophiles. Headquartered in Southport, and driven by a philosophy rooted in technological innovation and sonic purity, iFi has redefined the digital music experience. The LAN iPurifier Pro is a prime example.

Active Signal Regeneration – A Fresh Start for Every Packet

Beyond isolation, the LAN iPurifier Pro actively rebuilds the Ethernet signal. Advanced digital circuitry takes the signal after optical isolation and cleanses it of errors and distortions. Each data packet is returned to its ideal state before reaching your audio gear—resulting in reduced jitter, improved timing integrity, and a more coherent, immersive soundstage.

Crushing Jitter and Timing Errors

Jitter—those microvariations in signal timing—is a notorious enemy of digital audio. Even minor timing issues can flatten dynamics and sharpen timbre unnaturally. Thanks to its optical isolation and active regeneration, the LAN iPurifier Pro neutralizes jitter at the root, delivering precise synchronization and a more focused, natural soundstage.

A Plug & Play Solution for Audiophiles and Pros

Despite its sophisticated internals, installation takes seconds: plug it between your router or switch and your streamer, media player, or DAC. For best performance, position it as close as possible to the final playback device. No need for complex networking infrastructure or exotic power setups—it’s an instant upgrade for your digital audio chain.

First of Its Kind with This Performance in a Compact Format

The LAN iPurifier Pro is the first in its class to deliver such features in a sleek, immediately deployable form factor—perfect for home or semi-pro environments.

Upgradeable Power: Extreme Performance with iPower2 and iPowerX

Powered via USB-C, the device can run on standard supplies or be enhanced with iFi’s iPower2 or iPowerX units. These provide ultra-stable voltage and noise levels up to 10x lower than conventional audiophile power supplies, thanks to Active Noise Cancellation II technology—recommended for purists looking to eliminate all residual noise from their systems.

Real Performance, Audible Gains

What you get from the LAN iPurifier Pro:

• Smoother, more realistic streaming sound: less harshness, more depth
• Lower latency and more stable network performance, even in crowded environments
• Optimized results in multichannel, media center, or high-resolution server setups
• Full compatibility with Ethernet devices including streamers, DACs, NAS servers, and audiophile routers

In high-end audio, every detail matters. Network integrity is often overlooked—but it forms the backbone of today’s audio systems. The LAN iPurifier Pro isn’t just an accessory: it’s a technical necessity for those who want to extract every breath and nuance from their music.

With patented technology, measurable performance, and plug-and-play simplicity, the iFi LAN iPurifier Pro stands as a benchmark in audiophile-grade Ethernet isolation.
