iFi LAN iSilencer – Ethernet Signal Noise Filter for Hi-Res Audio Systems

I ordered the iSilencer because, after adding ifi devices to my SoTM SMS-200 streamer, I still had the feeling something was missing. The ifi psu, re-clocker and DC filter each made improvements, So I guessed the iSilencer would do something. The only question was how much and would it be worth the cost? The quick answer is yes!I purchased the iSilencer for my headphone system but first tried it on my Firetv cube. The result was better sound, colour and image. I found myself watching the Ultra HD remake of Roadhouse thirty minutes into the film when I only intended to watch a few minutes.Next was the streamer. Again, I was almost through a whole album when I only intended to listen to one track.As much as I hate hi-fi cliches, an invisible veil did seem to be lifted, allowing me to hear details previously missing. I’m guessing this was caused by electrical noise in my switch. Oddly, I had previously tried replacing the supplied psu’s of the router and switches with ifi psu’s, assuming I would see or hear some improvement in either TV or hi-fi. As nothing seemed to change, I guessed the problem was elsewhere in the chain. It seems the switch was the bad boy after all.The moral of this story is, the 'bits-are-bits' myth falls apart in the real world and I need to order a second iSilencer for my Firetv cube.***** UPDATE *****I had to reconnect the iSilencer to my Amazon Firetv Cube because the image on the TV screen looked a little blurred after removing it to connect to my streamer. There was no choice but to order another iSilencer.As it has been connected to the always-on Firetv Cube for nine days, I had the opportunity to judge what impact burn-in has made. Taking the nine-day-old iSilencer and plugging it into my streamer, I was surprised to hear much deeper and wider sound stages on most tracks. Also, more reverb has been revealed and that gives clues to the recording space used.The 1977 debut album, Fanx Ta-Ra by Sad Cafe, always sounded poorly mastered to my ears. I have it on vinyl and CD and both sound thick and congested. The iSilencer helps a little by opening out the sound stage a little. I suspect the CD version sounds better because jitter introduced by the switch has been removed.For me, this has been a worthwhile upgrade. Some claim to hear no improvement at all, so I think it probably comes down to how resolving your system is.

I have a relatively modest system comprising stand-mounted KEF LSX active streaming speakers and an SD Acoustics Gemini subwoofer.Last year I added an Ifi AC Ipurifier to my mains distribution block, and noticed a significant improvement to the system. I decided to try the LAN Silencer to see if it would improve things further.My KEF speakers are hardwired together for the best quality replay, and I have my 'master' speaker hardwired to my (TalkTalk) router. I simply turned off the power, unplugged the LAN cable, plugged the LAN Silencer directly into the router, and then re-attached the cable to the back socket on the Silencer. It took far less than one minute to do!On power up the results were immediate and very obvious. The whole system souds far more musical and lucid, with greater focus, soundstage depth and precision, and a complete absence of the 'grainy' sound that sometimes plagued more dynamic material. Bass goes deeper and there is more 'air' aound individual instrruments with better timbral rendition. It is a definite system upgrade, and well worth the money IMHO.

There are many "knowledgeable people" who will tell you that digital sound is just 0's and Ones - and as such nothing can affect the sound quality of streaming audio.They will also likely tell you that when files are transferred through an ethernet cable they either arrive perfectly or don't arrive.Now the latter is true but streaming audio is not just about getting the digital signal through but also the consistency of the timing of the signal, and also it's lack of noise interference.This is where the Lan isilencer is effective, is it night and day? probably not - is it worth having? Yes.

I’m an ordinary audio loving kind a guy ! What can I say about this little ifi lan Isilencer … after ten or so minutes everything changed ! I plugged it into the back of my router then off to my Wiim ultra to my DAC to my Yamaha amp and all of a sudden things are much much clearer. I’m not going to get all technical about sound stage and width etc etc just things are WAY more clearer ! I have come to realise that all the little things you do can make a collective big difference. So I highly recommend this device, I suspect for the lower end audio equipped of us it’s a real winner, but I’m sure of you have the budget for hi end expensive stuff then this isn’t for you. However as Amazon offer the 30 day money back then give it a go and see.

I wasn't entirely sure of how much of a difference the iFi LAN silencer was going to make in my system but felt I could always return it if there were none or the sound had been made worse. It's not going back. This is plugged into my Bluesound Node 2i feeding an external DAC with Audio Clock Trim disabled on the Node. My experience of this LAN silencer mirrors that of the many positive reviewers here in that it has taken my system to another level. Improvements have been made in every aspect of the sound and particularly in terms of atmosphere and image depth. Of course all systems may sound and respond differently with the silencer installed but I would strongly recommend you to try it. I thought my system sounded good before but this has produced a quite unexpected level of upgrade.

I have a quite a high end system about 15k worth. This thing held the sound back, which in a little way was nice. However it also started causing some drop outs. Returned. Perhaps if you have a cheap system it might help something.

Good value filter, compared to others out there, does a reasonable ,sonically improving job but not robust and poor build quality, they cannot support there own weight with cable attached fall apart.

I really thought this was going to be Snake Oil & fully expecting to return it. Used with a Naim NDX-2 & Audioquest Vodka, instant improvement: Deeper solid bass, extended top end, great vocals & an overall more analog presentation. A bargain in real terms.

すでにノイズ対策が進んだシステムにPCやルーター、バブを組み込むときに最低限の静電容量変化で効果があります。

Difficile à dire s'il y a vraiment une différence car j'ai un autre filtre avant de passer par celui là un multi-connection. Je pense qu'il est conseillé de ne pas mettre un câble trop rigide sinon le bout du filtre (rj45) se décolle facilement après un certain temps ! Personnelement je trouve le plasque un peu léger pour le prix !

Excellent noise filter. Improved transmission.

I didn't have much concern about buying this as I've been finding iFi products to work. This is no exception. In A/B listening, I can easily hear a distinct difference. It likely reduces the noise floor as where I hear the differences is in micro-dynamics, instrument clarity and vocal dynamics. The vocal dynamics are especially beneficial as they carry a lot of the emotion of the performance. After putting in the iFi device, when a singer lowered the volume for a particular phrase, rather than sounding weaker or like they're mumbling, it is clear, with intensity and solid vocal weight; just at a lower volume. This is a very nice improvement for such a reasonable price. The price is far less than 1% of my system value, but it's far, far more than 1% more enjoyable. You cannot lose by giving this a try.

je n'étais pas sceptique quand aux résultats possible , un peu perplexe tout de même ! je l'ai branché en premier lieu sur la box tv d'Orange et j'ai tout de suite trouvé l'image plus douce , plus fluide , des couleurs moins " heurtantes" avec l'impression d'une meilleure netteté , d'une image moins " poussiéreuse". fort de ce premier constat positif , je l'ai branché en entrée de l'ordinateur qui me sert pour écouter les radios internet. L'amélioration est plus subtile , moins évidente au premier abord. Il suffit de l'enlever pour se rendre compte que son apport est bien réel !
