Passive LAN Filter for Cleaner, Stable 2.5GbE HiFi streaming

Key Technologies

Designed for 2.5GbE and Gigabit Networks

Supports both 2.5GbE and Gigabit networks for wider device compatibility.

Zero-Noise Passive Operation

Passive, power-free design to avoid added noise and keep installation simple.

Galvanic Ground Isolation

Reduces transferred noise and ground-loop interference between connected devices.

EMI Noise Elimination

Eliminates electromagnetic interference for a cleaner and more stable audio network.

Ultra-Low Noise Transmission

Reduce loss and crosstalk for more stable, reliable signal delivery.

Pitch-Black Audio

Creates a quieter background for greater clarity, focus, and musical detail.

Shielded Connectivity for Flexible Audio Integration

Shielded Connectivity for Flexible Audio Integration

Features dual connectors and a fully shielded interface, allowing easy deployment between the router and audio switch to reduce network-side noise before it enters the dedicated audio chain.

Simple plug-and-play design also allows flexible placement between the audio switch and streamer, where it helps further refine LAN signal quality and preserve cleaner signal transmission before playback.

High Isolation, Low Interference

The Silent Angel LF-SP is a passive inline LAN filter built to clean up network noise before it reaches a hi-fi streaming system, sitting between a router and an audio switch, or a switch and a network streamer, without needing its own power supply. It supports full 2.5GbE speeds alongside Gigabit, 100, and 10 Mbps auto-negotiation, so it doesn't bottleneck network bandwidth while filtering the connection. Dual shielded RJ45 connectors provide galvanic ground isolation designed to reduce ground-loop interference and EMI noise transfer between devices, while its low-noise transmission path aims to minimize crosstalk and signal loss across CAT5 through CAT8 cabling. At a compact 108 x 32 x 26mm, it's small enough to tuck inconspicuously into an existing network run. Silent Angel markets it as creating a quieter electrical background for greater clarity and musical detail in a streaming system — a tweak-category product where the sound-quality benefit is the manufacturer's claim rather than an independently measured result, so it's worth approaching with that context for anyone chasing audible improvement from network-side filtering.

Silent Angel LF-SP Passive Lan Filter, Stable 2.5GbE Hifi Streaming (Silver) Frequently Asked Questions

Q What does the Silent Angel LF-SP Passive LAN Filter do in a HiFi streaming system?
A

The Silent Angel LF-SP is a passive LAN filter that sits inline on your Ethernet connection. It cuts the electrical noise and interference that can travel through network cables into your audio gear. Galvanic ground isolation blocks noise transfer and ground loops, and its low-noise design reduces signal loss and crosstalk, giving a quieter background with more clarity and detail.

Q Does the Silent Angel LF-SP support 2.5GbE networks?
A

Yes. The LF-SP is built for modern 2.5GbE home routers and leaves room for future network upgrades. It auto-negotiates 2500, 1000, 100 and 10 Mbps, so it also works on standard Gigabit and older networks.

Q Does the Silent Angel LF-SP need a power supply?
A

No. The LF-SP is fully passive and needs no external power. Without a power supply there's nothing to add new noise to your system, and setup is just plugging in two Ethernet cables.

Q Where should I install the Silent Angel LF-SP in my network?
A

It has two shielded RJ45 female connectors, so it goes inline between two network devices. Common spots are between your router and an audio-grade network switch, or between the switch and your network streamer. At 108 x 32 x 26 mm, it fits easily behind an equipment rack or in tight spaces.

Q What Ethernet cables are compatible with the Silent Angel LF-SP?
A

The LF-SP works with CAT5, CAT6, CAT7 and CAT8 Ethernet cables. Its shielded interface is rated for low insertion loss (≤ -0.5 dB from 1–50 MHz) and 1500 Vrms insulation. It operates from 0 to 85°C and 10% to 90% humidity.
