In addition to the above, the more I cleaned up the stream, the more trouble seemed to appear. Normally I would say if noise is the problem then it must be audible immediately. It should not take a few days to get effect. With crystals it's another thing they can slowly synchronize to other crystals. And this seems to be the problem when a stream became to clean. I think that is the problem I'm facing.
Here's also a picture from a router on a switching powersupply for the comparison with the above
Ok, cool. But that is usually not enough to lower the noise floor since the router it self is usually to noisy, even with a good power supply. The forums are exploding with people that physically disconnect their ethernet line by introducing WiFi extened/repleater. Some of these models can achieve and very low noise floor output, if having a really good power supply/battery. This is the route i took and it proved to be much better, even if cheaper and simpler. I can strongly recommend this site that has learnt me a lot. https://ethernet-sound.com/
They do measurements also. You need to use the browser translate function maybe.

I will look into it for sure thanks for the link. However I don't use Wifi at all. About the batteries I once did a test with a Wavelet Dac of a friend. I had a few 18650 cells from Sanyo Li-Ion. And also from panasonic. For the comparison I created a Mosfet 12Vdc powersupply. I must say it was a close call, but the powersupply came on top in a blind test. After this test I have used the batteries in my network for a while and disconnected the chargers when listening. It was pretty good and cheaper than a good powersupply. But then there was Farad.
Are you familiar with the noise floor of a battery? Farad power supplies are lab tested and have a significant lower noise floor than a battery. A few companies that used batteries for testing sensitive equipment switched over to use Farad Super 3's for even better results. Not to mention the Super 10's
The wrong reply button happened to me as well in another thread 🙂
My comment got lost... annoying.
A lot has happened just in the last months in this space. Ian Canada battery modules are great for usage in the digital domain, which they test there. In my opinion they are spot-on on that forum. I use their suggested WiFi extenders, Ian Canada Battery PS but the best hidden secret is that ethernet throttle cable!
