So what does it "silence" exactly in the Ethernet protocol
ifi LAN iSilencer
I discovered this Ethernet signal purifier for network audio streamers, just by chance, while surfing the internet. I have an extremely highly resolving hifi system. After reading all the positive customer comments and reviews, I said to myself, what the heck, only 89 bucks, let's go for it. After receiving the ifi, as recommended, I plugged it into my audio switch, then plugged one end of the ethernet cable into it, and plugged the other end of that ethernet cable into my DAC/Streamer. Now, I already have a variety of audio tweaks throughout my system, including my speakers. But when I added the ifi, the background got even deeper, darker and blacker. It was absolutely amazing!!! This little gizmo worked exactly as advertised!!! Highly recommended.

@audphile1 - trolling like asking how exactly it works? Let’s see. Manufacturer Web site claims actually a) galvanic isolation and b) EMI noise reduction. That’s it. No "soundstage improvements" or anything specifically audio. Good for them. Now, in transaction protocols only huge amount of noise matter and one would see it in Web browsing and Netflix stream first. I.e. transmission disruptions. drops and packets lost even after retries. It is easy to measure packet loss by going to any Internet connection measurement site and checking for packet loss. In any case, audio stream is like 10 megabits per second tops and typical connection (like mine) is 500 MB/s. So that audio stream can handle serious packet loss and retransmit will recover it. It is all pre-buffered anyways. Just checked - zero packet loss at 550 MB/s from me to the cloud with many, many connections, routers and optical/electrical conversions, reclocking and buffering. Is this productive enough for you, mr teacher? Does Amazon use any of such devices to improve "reliability"? Reliability is huge for cloud providers. Even 0.1% matter. Oops, they use Belkin cables. |
@zlone - good. Ah, but manufacturer claims improvements in transfer :-) so it is already subject to truth in advertisement. Next, here is quote from the iFi site - "The LAN iSilencer removes the electrical noise that distorts the audio signal from your network." Huh? What audio signal in my CAT6? Where? Now, if noise to streamer is an issue. First, it is a twisted pair, correct? So we are talking POOR implementation of the input analog receiver and ADC in the network hardware of the receiver. Sounds unlikely since chips and solutions are 99% standard, nothing is custom there. So next, you may say - leak EMI from network cable over to.... where? If streamer is combined with DAC - maybe... Get a shielded cable then. If streamer is an ARM PC with USB out - unlikely. Digital to digital over controlled protocols with recovery. Decent DAC is immune to USB noise and would have isolation at the input. In the worst case DDC like Denafrips Iris in front of the DAC would be a much better choice. |
@zlone - they go to great lengths not necessarily for tech reasons but to be able to sell the product so audiophile community. I love reading Nelson Pass. One of the best engineers making great gear. He obviously does not try and alienate potential customers with $$$ but he did say quite a bit about expensive power cables :-) If this is so important, then $79 thingy should simply be part of $2000 streamer. And it probably is.... |
@audphile1 - where did I say NP was against aftermarket? Don’t invent things. He said certified cables, supplied with the unit. Which is a regular good $50 cable. As is cable that came with $$$ Accuphase. If you don’t have engineering explanation to effects, I would suggest you to stop reading what I say. This information is not for you. |
