SilentPower
There is such a high demand for various devices that improve the quality and lower the noise of the power and the digital signals that feed our audio systems, that the well-known audio brand iFi decided to focus on this area and create a new sub-brand company called SilentPower.
This is not a coincidence though since iFi has always been a pioneer and continues to lead in this field, having in its catalog numerous related products. The PowerStation and various DC power supplies, like the iPower Elite, easily spring to mind if someone was asked to name a few.
A special category are the Ethernet filters that are inserted between the internet router and a streamer, undertaking the difficult task of cleaning the streams from electromagnetic noise and ridding them of the dreaded jitter. The company already offers three such models: the entry level LAN iSilencer, the more advanced LAN iPurifier Pro, and the newly arrived flagship OMNI LAN which is an advanced network switch.
SilentPower OMNI LAN
The OMNI LAN is a specialized network switch placed after the provider’s router and before music streamers (or DACs, servers, and media players with a LAN/optical input), tasked with suppressing jitter, noise, and all kinds of electromagnetic interference.
To achieve this, it uses three-stage galvanic and optical isolation along with additional signal reclocking. The secret lies in converting the incoming data to optical and then back to electrical, thus creating complete electrical isolation between the input and output. This procedure significantly reduces electromagnetic interference and noise.
After the conversion, the OMNI LAN regenerates the data stream through active circuits and a precision femto-grade GMT clock, offering extremely low jitter and stable synchronization across the entire network. The device also features configurable grounding modes (DC-RF, RF, ISO) for optimal noise control.

Design and build quality
The OMNI LAN visually resembles the familiar iFi NEO iDSD 2 and iFi NEO Stream devices. Not by chance though or due to a surplus of the same chassis but because these three devices are meant to be combined together to form a high-end audio system. The OMNI LAN has the task to feed the NEO Stream with a clean digital signal, and it in turn sends the streams to the USB input of the NEO iDSD 2 for the best possible sound quality.
This is a solid and well made device with an aluminum chassis that has a clean, industrial design in a dark gray finish. The OMNI LAN is compact enough to fit virtually anywhere, you can even place it in a vertical position with the aid of the supplied stand. Dominating the front panel are the aluminum rotary multifunction knob and the 2” TFT color display that can be automatically oriented depending on the installation position of the OMNI LAN.
Connectivity and operation
The OMNI LAN offers a total of 13 ports that are all located at the back together with the DC input and the 10MHz BNC external master clock in/out for synchronised system timing. From the 13 ports, 8x RJ45 and 1x Optical SFP are standard ones while 2x RJ45, 1x Optical SC and 1x M12 are ultra clean for audio use. The TFT display provides real-time bandwidth monitoring for all 13 ports.
The OMNI LAN is plug ‘n play like any other network switch. Just connect your provider’s router to one of the standard ports and use the clean ones to send noise free and low jitter streams to your network audio devices. Naturally, you can connect various other devices to the OMNI LAN such as TVs and network attached hard drives so you can use the OMNI LAN as a multimedia hub.
You can control and configure the OMNI LAN with the aid of the physical buttons or the smartphone application which also provides real time monitoring information and easy firmware updates.
Accessories and the power supply
To operate, the OMNI LAN requires a 15V power supply which is included in the package, along with one RJ45 cable, four anti-slip adhesive pads, and the vertical stand mount.
And just when one would expect to find a high quality SilentPower power supply (like those included with the NEO iDSD 2 and NEO Stream), the company surprisingly decided to include a basic off-the-shelf power adapter in a device of a respectable cost. A misstep from a marketing standpoint of view, made for obvious reasons.
Associated gear
The acoustic evaluation of the OMNI LAN was conducted in combination with the Volumio Rivo Plus streamer and a reference 2-channel speaker system that consists of the Audio Physic Spark speakers, the Lab12 dac1 reference and the Lab12 integre4 Mk2 (Toroid Version) tube integrated amplifier. Headphone listening was done with the same DAC and the Flux Lab Acoustics Mentor headphone amplifier while I also watched plenty of online content on a smart TV. Interconnect, speaker and headphone cables are all made by Lavricables.
Listening impressions
The OMNI LAN does exactly what it promises, which translates to crystalline sound with improved clarity, incredible silence, extended depth of field, and greater spatial accuracy. The timbre of the sound eliminates any hint of digital footprint, however it doesn’t become what we’d call fully analog and organic.
In an era where streaming services gain more and more popularity, the OMNI LAN helps to make digital streams sound less digital and become more alive. It is really difficult to beat an all analog set-up but the OMNI LAN can help you get closer to the goal.
The device enhances detail retrieval and definition, the treble becomes smoother and the bass more textured, the listener can easily focus and follow various instrumental groups or discern the finer details inside the mix. The differences with and without the OMNI LAN are easily noticeable even in a mid-level headphone system but they become more apparent and better appreciated in a higher-end audio set-up.
The OMNI LAN undeniably upgrades the overall sound quality, but there is a chance it may not match well with an especially analytical and transparent sound system because it will further enhance those characteristics. To each their own, of course, as many people will appreciate the extra amounts of clarity and transparency, combined with the benefit of the reduced digital glare.
More impressions
Finally, I must emphasize that I was genuinely impressed by the great improvement in image clarity and sharpness while watching Netflix content on the TV. An application of the OMNI LAN that should not be overlooked and can be combined with the audio to elevate the total performance of a home cinema system.
The company might have skipped on a high quality power adapter but luckily enough I had at my disposal the FiiO PL50 linear power supply that further improved clarity and silence.
Kindly note that I have a simple LAN router so I haven’t had the chance to test the optical or the M12 ports.
In the end
The SilentPower OMNI LAN is a high quality and very sophisticated network switch that does exactly what it promises and rids digital data from noise, interference and jitter, thus delivering pristine signal to music streamers, servers and media players. A reasonably priced device for what it does, that you can use to elevate the performance of both audio and AV systems.
iFi audio, the mother company, has always been generous with the included accessories but this time forgot to provide a high quality power adapter as they usually do in similarly priced products. And this is the only negative point worth noting when it comes to the evaluation verdict of the SilentPower OMNI LAN.
