iFi LAN iSilencer – Ethernet Signal Noise Filter for Hi-Res Audio Systems – Removes Electrical Noise with Galvanic Isolation – Plug-and-Play RJ45 Isolator

First, let me tell you about the system this is being used on. The power for my system runs through a hospital grade outlet into Furman PST-8 Digital Power Station power conditioner/surge protector, and from there into a Cullen Cable Gold Series power cord. The wired signal is carried via a Cat 8 Ethernet Cable. Both are fed into a NAD C700 Integrated Amp with built in BluOS Streaming. The Acoustic Zen Satori speaker cables are used to feed sound into Monitor Audio Silver RS-6 tower speakers. Prior to the installation of the iFi LAN iSilencer I was experiencing solid and great Mid-Fi sound, streaming Hi-Res Qobuz with neutral, clear detail. I must state that I was skeptical of the iFi LAN iSilencer actually making any difference and was fully expecting to return it after I tried it. To my surprise after installing it into the LAN port of the C700 and plugging the ethernet cable into the end of it, the sound became smoother and warmer while still being very detailed, with better stereo separation of voices and instruments, and better sound staging. Was it a night and day difference? No, but it was an obvious difference and well worth the under hundred dollar cost. With nothing to lose to try it, it’s a no brainer!

I am totally impressed with the iFi ethernet filter. We stream the typical video channels & also audio. We can see the video improvement - mainly better colors & zero latency. The audio improvements can be easily heard too.I have 2 of these installed right into the ethernet switch. The first is in port #1 & the second is in the port that feeds the ethernet cable for our TV.If you are into streaming audio or video, give these filters a try. FWIW - we have gigabit internet through Spectrum & a simple home network. Hard to believe, but your internet signal might be dirty & benefit from galvanic isolation. Mine certainly did.Even though I use 2 of these iFi filters, you only need to start w/1.

I put off trying one of these for a very long time. I’m very sorry I did. I installed this between my modem and router, hoping everything connected to the router would benefit.It sure did. Obviously clearer, more focused sound. No change in bass or anything, just more real sounding, especially with voices (music and dialog on an Apple TV box). May try another on the input of my music streamer.Other than Isopod Minis, this is hands down the best under $100 tweak I have ever tried. I don’t know why it works and don’t care. Try it before you declare bits is bits.

Reason I didn't give this a full 5 stars was because the impacts are subtle, but this could be because my streamer/player and entire system is finely tuned with each component having EMI/DC Filters, Linear Power Supplies and Super Capacitors. On a regular system this iSilencer could have a larger impact, but I can only rate for my own system with my own experience.When a system is finely tuned, chances are that when you add something to it then something else will fall out of balance. Not so in this case! Immediately after installing the iSilencer I did not notice the width of the soundstage collapse or feel the sound had a 'filtered' nature to it. What it did was have more depth to the bass and cleaned up the bass more than anything else. This in turn gives a more detailed but natural impression of the soundstage and gives a slightly more holographic effect. It wasn't night and day but it was an improvement. In this hobby where improvements at this level are hard to come by and rather expensive, for less than $100 this was a worthwhile tweak. Can I live without it? Yes, but now that it is in my system would I want to take it out to save $100? No way! It is priced well for what it does and gives a 5% to 10% improvement in my system. Cleaning up the lower frequencies also gives more richness and naturalness to male vocals. Good tweak, but like all iFi products, you have to experiment to find out where in the system they make the most impact. Not the same impact as their iPurifier3 for USB, but something like a 'cherry on top' of a finely tuned system without going all out on a Network Acoustics Muon Pro filter.

Nifty little device -- connected easily and works without any issues. Now... does it improves the sound? This is very subjective as I do not have objective measuring equipment to prove anything quantitatively. However, when listening to my Eversolo DMP-A8, it feels like my music is more clear, with more air and resolution. Could be psychological, for sure, but I'm keeping this in my system!
