Maybe fibre could be used similarly to a WiFi extender but fibre definitely isn´t as effective as airgapping since you can hear changes in the network even prior to the fibre, even if many say that shouldn´t be possible...

Pieter, do you have one certain volume position that you use? I ask since my experience is that when the noise is removed the sound gets less shouty, which is perceived as less energetic.

But you can now turn up the volume instead, a lot, without it getting loud and fatiguing. Thanks to this you suddenly have better dynamics, since you can crank the volume more without it appearing to be loud. It basically starts sounds more like vinyl and not like digital music.

That is my view, and i feel that it is a paradox that is easy to miss if you focus on a certain "fixed" volume level.

found this picture also. What is actually inside the Networks Accoustics Muon Pro? Well, it looks to be the ferrit core chokes...

Good morning, Yes I found that picture as well, but I'm not sure it's the latest version. This one is only 100Mbit I think because of the 4 wires that are used.

Due to the fact the phase noise chanched in the video of Hans Beekhuizen. I think something else is going on. I can't believe it's only the filtering yet 🙂 Please maybe read this twice 🙂

What has happened in my system is that the trouble I had with dark sound reappears after I put a filter in each section of my small network. I think the dark sound is caused by bad phase noise. Due to crystals that synchronize and unsynchronize. Because the negative effect did not take place when I only put a filter in the last section. I'm positive that the strength and or stability of the signal in each section is more of a concern than the filter itself. I think the crystal of the sending device must not be influenced by the receiving device when it's talking back. When the signal between the sending device and the receiving device is on the same level I think they will float all around and there's no stable factor. One must be the clear leader.

I think it causes this same problem when I put a high grade powersupply on each device. A powersupply which is ultra clean and sets a far more clean and stable signal in the path than a SPS will do. This is measured and this is proven. When the signal becomes on the same level in each section the sending can't lead that easely. One could think that this would be the same problem with a switch mode powersupply, but I think that the instability of this signal causes another effect and no crystal seems to influence any other crystal at all.

When putting the ferrite filter only in the last section this section became of different strength. The inductor will weaken the signal a bit. The cleaning factor of the stream built by a high grade powersupply is much smaller than on a stream built by a SPS, but the weakening of the signal and the EMK's will always be there. I think the downstream matter. The sending crystal becomes the master and the receiving crystal becomes the follower. The dac itself will be influenced less, because the crystal in the network does not float around that much and the phase noise level will benefit :-). I will dive deeper, but due to all the testing that I already did in the last few years this is my conclusion at the moment. For example in one test I have used 8 Pink Faun ethernet isolators. Each isolator is a filter as well all together I think they can bring a big filtering quality. Putting them all in series one by one weakened the signal that much that the sound became sharp as a serrated knife. It was perfectly readable, but the bits became very small

Hehe, I can imagine the frustration if it actually turns out to be as simple as they are concluding on the German site, when you have worked with something so long.

I am not saying that it is this simple, for sure, and i also haven´t tested much other things my self, to be honest, so i can´t judge the greatness of this compared to other solutions. However, i have to say, just based on following those German guys for a couple of months now, i really think they have been taken a very credible systematic approach (very German, in fact 🙂 )that has lead me to think that they really have nailed it 🙂
