Yes, I had that as well the first few times. Now I copy my text into a text file
Thanks for this article!
In the first paragraph is written; common mode current on the wires. I have to think about this, because an ethernet connection to a switch is always galvanic isolated with the shield as an exception.
In the second paragraph is written; That data is not being corrupted in any way. I know that's true, but what about the shape of a bit? The bits are just an analog signal that is interpreted as digital data. And on the DAC it's the other way around. I think the shape of the bit is an important factor.
In the third paragraph is written; In other words that data is just passed trough, but what about noise? I think that noise can be past true as well. Think about this: an electrical noise spike is converted to light and on the other side converted back from light to an electrical noise spike.
Personally I found out that at least in my system fiber optics can't compete with copper devices. I really tried hard. I still have a few hundred meters of fiber optic cables and several converters. I think the clock signal is passed trough. The data tap is built by a clock and sent by a clock and catched by a clock.
I will look into the link you have sent and maybe see you back in a few months. Good luck!
About point 5 ethernet cables. I must say that I was convinced for more than a decade. That the quality of ethernet cables are very important for high end audio systems. I think that I wrote over 500 articles on the PS audio forums back in 2o12 and also more than a few back in 2015 on the Alpha Audio website. I tested and bought really high grade cables in the past and they did make a clear difference, but in the past few years I also found out that when an ethernet system is tuned to the max. That the difference in cabling will be still there, but I can't say I like high grade cables over normal cables any longer. Actually normal cables sound more neutral than
Wijnand, what i don´t understand is that you seem to have a computer device physically connected in your signal chain? In my opinion you are never going to get to a real low noise floor as long as you have that.
A good audio streamer has amazingly low internal noise floor potential that most people ruin the moment they start hooking up gears/cables to it. If you just make sure that the incoming ethernet signal is VERY clean and use a good PS (as you stated) then a good audio streamer will be able to keep that low noise floor and send a clean signal to your DAC. Note that you must use the mobile device to remote control the audio streamer!
In my opinion no additional clocking, or other "mumbo-jumbo" 🙂 is then needed. The challenge is to understand how to lower that ethernet signal noise floor. A passive filter, like the Networks Accoustics Muon Pro streaming systems prove that it is actually quite simple.
Hi Tobias, Thanks! and yes of course I understand what you're telling me. The reason I connected the PC was because my network was in trouble. The only thing in my network was a router fed by an ultra clean powersupply. I also made scope pictures back in 2020 which made clear the data stream was very clean.
