LAN iSilencer Audiophile Ethernet Dongle Claims to ‘Quiet Your Network’

iFi-Audio has released the LAN iSilencer, an audiophile accessory aimed at “silencing your network”. According to Japanese Ethernet dongle designers, this product removes digital signal interference and protects audio signals from noise. For blissful audio, we recommend plugging a thumb drive-sized device into his RJ45 socket on your router, switch, or wall.

Some background information on “noisy” network audio issues and iFi-Audio LAN iSilencer Artwork shared on product pages. An important design feature said to help digital audio 0s and 1s is the “zero jitter memory buffer and electrically isolated input”.

The presence of buffers indicates that the network signal has some built-in delay. This is less than ideal for many PC use cases. On the other hand, the concept of galvanic isolation is used in mainstream electronics. Circuit designOn the topic of galvanic isolation, iFi-Audio states that audio signals passing through them are not affected by interference from ground potential differences and AC power transients. I’m here. No before/after audio charts or similar details have been shared to back up the audio quality/noise reduction claims.

iFi-Audio shares some technical specs of the LAN iSilencer, which retails for the equivalent of $109 in Japan including consumption tax (10%). The device supports 1000BASE-T /100BASE-T /10BASE-T transmission speeds, has a shielded case, weighs 17 grams and measures 73.5 x 19 x 16 mm. In the examples where this dongle is plugged into various devices, it seems to be prone to accidental damage as it is a rugged device sticking out about 3 inches from the Ethernet jack.

What we can say for sure is that iFi-Audio’s claims seem a lot less wild than other recent audiophile computing gear we’ve reported. For example, the $1,250 AudioQuest Diamond RJ/E Ethernet Cable combines “Solid Perfect-Surface Silver Conductors” with carbon-containing synthetic fibers to shield the wires and protect them from RFI. Even more bizarre are claims about $500 SATA SSD cables with Superstar Crystals. This seems to work like a charm even without connecting to the SSD. In the last few months, we’ve also reported on his SSD for audiophiles and similarly targeted Ethernet switch UEF.
