iFi LAN iSilencer - LAN Signal Noise Filter - Remove Electrical Noise - Ethernet Isolator for Hi-Res Audio Systems (RJ45)

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.

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.

Used with Naim Uniti Nova & Neat SX1 speakers, connected directly into rear of unit. Definitely has added a little extra sparkle to the top end & improved imaging spaciousness. Not night & day, but worth having.

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.

It seems an expensive item at £89, but the amazing thing is that it works well. The sound stage is noticeably deeper, making musical instruments easier to place. Streaming music and video is more enjoyable. Worth a try.

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.

It's hard to imagine the improvements that can be made by cleaning up the ethernet signal. I always thought my system sounded pretty good, but after reading a couple of reviews I decided to try it and after plugging it into my Bluesound node 2/Cambridge Audio 851/ATC SCM11's, I sat back and listened in amazement. The background noise had fallen, detail, dynamics, depth and soundstage have all improved and it's more relaxed and easier to follow vocals and individual instruments in the mix. I believe it can take a couple of weeks to bed in so if it's going to get even better then I'm sold on this little gadget. It's a definite keeper for me and definitely worth a try if you're looking to squeeze some more out of your system rather than making an expensive upgrade.

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.

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 !

ネットワーク・オーディオを始めましたが、LAN関係にはあまり手を入れていませんでした。 今回、fi audio LAN iSilencerを導入したところ、音質、S/N比が驚くほど向上したので、再度購入しました。とても良かったです。

Prodotto di qualità. È assai utile per migliorare il flusso audio qualora non si disponga di una porta ethetnet a bassissimo rumore e con isolamento galvanico. Il miglioramento è palpabile e udibile. Agisce da filtro e non altera il suono rendendolo più audiophile. Io l'ho collegato direttamente ad uno streamer secondario nella porta ethernet in entrata. A mio avviso si sente meglio che collegato alla porta ethernet in uscita del router. Consigliato in tutti i casi i casi in cui non si disponga di una porta ethernet a basso rumore. Buono anche per il video ma non come per l'audio.

He esperado un tiempo para poder poner una reseña con argumento. Hice varias pruebas con el aparato y sin él, y en mi caso ha mejorado un 10% la calidad de sonido en mi equipo high-end. A un par de conocidos, que se lo he dejado, dicen que no notan nada de mejora. Creo que depende mucho de la instalación de audio de cada uno. Pero os explico el mio. Desde que sale la música de mi NAS o internet que está en una habitación, hasta que llega al Streamer del Salón, ni os cuento por todo el sistema que pasa la información. En casa tengo 2 router, metros de cableado, los archivos están en el NAS, y los reproduzco en el streamer. Así que la info pasa por varios cacharros, y mucho cableado. Sin contar las tomas de corriente, regletas, transformadores, y dispositivos como tv, apple tv, receptor av, y un largo etc, que tiran de los dos routers y de la misma red. Los cables de red, algunos están próximos a los transformadores y cables de electricidad. Así que quería asegurarme que al streamer llegase los datos, lo más limpio posible. Y así lo tengo instalado, justo a la entrada de red, del Bluesound Node, tengo el Ifi Silencer. Y como decía en mi caso funciona. Mejora la dinámica de las canciones. Sin él, se oyen más lineales y planas. Con él, se nota más diferenciado todo detalle del tema musical. Si no tienes tantos cacharros conectados, quizás no notes diferencia o no lo necesites. En mi caso ha sido una mejora del 10% por ponerle una cifra. Quizás suene a poco, pero para un equipo audiófilo, en mi caso es mucho. Esta claro que es un aparato para personas que somos exigentes con el sonido a alto nivel. Entiendo que con tanto cableado y cacharros, llegaba más interferencias al streamer. Ahora no. Ese es mi caso particular y experiencia.

Made a meaningful improvement in streaming SQ for relatively small investment. Highly recommended if you have a resolving system and don't want to invest big $$$ into audiophile filters and switches. Provides wider/deeper soundstage with added refinement and reduced digital glare. Also improves the SQ for local playback by isolating server/streamer from noisy network switches.
