Electrically isolate your network, idea/suggestion/solution

[Pink Faun]

Hi activist38, A new website is in the making for Pink Faun, so the link in your post is not active anymore. here's a photo and some more information about the LAN isolator:

The Pink Faun LAN isolator provides galvanic isolation between the device that is connected to the network and the network itself. This without loss of speed. Even devices that play from an internal HDD and only use the network for operating and updating the firmware benefit from the LAN isolator.

A network cable from the media player connected to an active modem/switch is a transmission hatch for high-frequency noise. With normal computer use such as e-mailing or surfing the internet, the high-frequency noise has no influence on the user experience. However, high-frequency noise that enters directly into the digital audio device through LAN is very undesirable. This influences purity in the high, which causes the space information to become blurred. The Pink Faun LAN isolator will ensure that the sound is less smudged, making details more audible, providing a better soundstage and a black background which in turn increases the dynamics in an audio system.

The Pink Faun LAN isolator can be used on any audio device connected to a LAN network, even when the network is not used to stream music. Once the audio device has been assigned with an IP address and is active, the LAN isolator has a positive effect on the overall sound quality.

€179???? Snake oil of the highest order if you ask me.....

Hi NiToNi,  A lot of snakeoil, absolutely 😉 😁

Please take look at this interesting video about network tweaking. Of course you are free to contact me to test the LAN isolator yourself.

Yup, just as every Ethernet jack in the world has a set of coils/"transformers."  The really nice (more expensive) ones can have as many as 12 cores per port:

 

Of course this is not the same as actually putting the signals though differential digital isolators and flip-flop with separate clocking and power domains (the key uniqueness of our forthcoming product). 

 

 

As you point out correctly all ethernet equipment has to include a certain level of galvanic isolation from the cable. But as you also point out there’re differences between the transformers used (the more expensive ones). Mostly used ethernet ports has integrated transformers in a very small space. With discrete ethernet transformer (like the LAN isolator) there’s less crosstalk and we can choosing modules with better common mode rejection figures than the integrated connector module.
