iFiLAN iPurifier Pro – Ethernet Noise Filter with Optical Galvanic Isolation, Jitter and Error Elimination – Plug-and-Play for Enhanced Audio & Video Streaming Quality – USB-C Powered

It is amazing little thing what makes a difference!My tv get better color and contrast and music sounds more relaxing and soft.

Excelente producto, realmente mejoró y limpió la transmisión de datos.

I was skeptical about this one, but decided to try it. I used it on the iFi zen streamer, a unit I was already happy with (I'd added an external linear power supply and was already running its USB output through a DDC) - so I expected I'd pack it up and return it ... but when I first heard a difference, it warranted many listening sessions. As great as the sound already was, there was what felt like an added dimension of clarity, and that was enough to keep it. For me it's a relatively small price for the improvement.

Part of an upgrade to my streaming system (that included all CAT 8 cabling). Removed some glassiness in the top octaves. Overall sound now more relaxed and analog.

I installed it between my router and streaming tv. It not only improved the audio quality but also the picture. I compared to wifi only connection and this one won out. Great product. I powered it by the ifi 5v noise cancelling power supply.

Took the noise completely out of my home network.My Ambeo max & Apple TV has better audio and video. Both my 2 channel setups sounded much improved when streaming. This thing does what it claims. Well done iFI Audio!

I installed this and then all I would hear is a weird loud crackling noise no matter what I would play. It sounded like dinosaurs were fighting!

This device is built well and easy to connect and get inline. I purchased it for use with local LAN audio streaming. I wanted it to work and lower the noise floor or improve overall sound. I have very good power, and great audio hardware so I was unable to hear any difference. I tested sound on many albums across 2-3 days and just couldn't hear any added benefit so I returned the item. I do believe other hardware would benefit from this solution - in my case I was willing to keep and use it but the benefit wasn't there to justify the cost.
