activist38 Posted April 8, 2019 Share Posted April 8, 2019 hi i'm new. Visited here as a guest and seen a few members commenting on the FMC way to isolate noise from a system. Members are saying that the second FMC is the problem because it comes after the optical cables and injects noise from it's own PSU back into the system - correct me if I am wrong? What I thought of is to plug a pink faun LAN isolator right into the FMC RJ45 output socket, and then plug your LAN cable into that unit. To solve the issue. Hope that helps. https://www.pinkfaun.com/index.php/pink-faun-lan-isolator-rj45.html Link to comment
Pink Faun Posted April 8, 2019 Share Posted April 8, 2019 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. activist38 1 Link to comment

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. activist38 1 Link to comment

esmit Posted April 11, 2019 Share Posted April 11, 2019 I think the journey for most people was: Level 0: cheap ethernet cable Level 1: fancy network cable (a la Audioquest Carbon) Level 2a: network isolator (Baaske, pink faun, others) Level 2b: 2 optical/FMCs, wall wart Level 3: replace wall wart with BOTWS/stabilized/ultracaps power. You can add 2a to 2b but I think general consensus is that level 3 gives better results. And then we have level 4: opticalRendu/specialized network hub/etherRendu/SoTM stuff which is very new/not delivered or compared yet. activist38 1 Link to comment

Ethernet RJ-45 specifies galvanic isolation, so how is this different? The obvious answer would be that it reduces common mode noise transmission. Does it? Custom room treatments for headphone users.

As I suggested it might improve the common mode rejection, which is expressed as a common mode rejection ratio (CMRR). It is known that transformers aka common mode chokes do this: http://52ebad10ee97eea25d5e-d7d40819259e7d3022d9ad53e3694148.r84.cf3.rackcdn.com/Acal-BFi-Laird-App-Note-1.pdf It would be helpful for manufacturers such as Pink Faun to provide CMRR values so that products can be reasonably compared.

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.
