We recommend placing the SmoothLAN Filter directly between your network and music streamer — this position delivers the greatest benefit in most systems. 

The SmoothLAN Filter is a purely passive device — it removes high-frequency noise and interference at the network input without using any external power. It contains six independent isolation stages and is designed to eliminate as much noise as possible at the point of entry, allowing your streamer to perform with greater clarity and stability.

The SmoothLAN Regenerator, on the other hand, is an active design. It doesn’t just filter — it rebuilds the network signal entirely. By re-clocking and regenerating the data stream using a high-precision master clock and ultra-low-noise power supply, it delivers a cleaner, more stable signal to your streamer. This reduces phase noise and jitter at a deeper level, allowing digital systems to perform with greater timing accuracy and detail retrieval.

Yes, although it is system subjective, the two products can complement each other. Place the Filter first (closest to the network switch/router) and the Regenerator directly before your music streamer. This combination provides maximum noise isolation and timing accuracy.

Some Ethernet filters use plastic to prevent case interaction with internal magnetic fields, but this leaves the device susceptible to external interference, which is likely even stronger. In contrast, our aluminium case, coupled with a compartmentalized design and EMI absorbing material, provides superior shielding not just from external electromagnetic interference but also isolates internal magnetic fields from each other.

No. The SmoothLAN can be used in either direction as Ethernet by its nature is a two-way signal.

The SmoothLAN limits the connection to 100Mbps by design. This has no impact on music streaming performance (even high-resolution services use a fraction of that bandwidth) and actually helps reduce high-frequency noise. Slowing the connection is part of how the SmoothLAN improves sound quality.

No. The SmoothLAN is entirely passive and doesn’t require any power, making it simple to install and maintenance-free.

Reducing network-borne noise allows your streamer and DAC to work in the best possible conditions, revealing more of the music detail already in the recording. The SmoothLAN doesn’t “change” the sound; it removes unwanted interference so your Hi-Fi can perform at its full potential.

While chaining two filters is possible, it can lead to over filtering – which may subtly dampen dynamics in some systems.. If you’re looking to take things further, pairing the Filter with the Regenerator could be a superior next step.
