A Home Network Experiment: Setup, Equipment Used, and Observations

[claudia5]

I was not saying that Ethernet noise is always audible or that it affects every system.
The only point was that, from an engineering perspective, electrical noise can couple in some cases even when the data itself remains bit-perfect.

Whether this becomes relevant in practice clearly depends on the specific chain, grounding, power supplies and overall implementation.
In many systems it may be negligible, but it is not physically impossible and in my case we eard the differences ( ai help me writing)

You clearly miss to know the very basics of networking. Pls stop posting AI beefed up nonsense here. Educate yourself. On the other hand you might just be a troll trying to have some fun(?).

No, you haven’t proven that.

im not a troll

i didnt measure . the differents in the sound was ovvius

There is your mistake.... I can give you a black box, tell you that it improves audio, yet have it do nothing and get the same reaction. This is why we measure. And this is why your testing is wrong.

Maybe not but you don't know how to properly evaluate audio differences. Until you do, what you are posting here is without value. Either learn why that is the case, or move on to some other forum where kind of lay intuition substitutes for audio engineering and science.

Complete nonsense @claudia5

This may not be relevant, but advice for everyone: NEVER use screened RJ45 cables domestically, unless you REALLY know what you are doing with distributed grounds. Unscreened RJ45 cable using normal IT kit guarantees ground isolation and full decoupling.

CAT3 unscreened is adequate for stereo, unscreened CAT5 is excellent for all domestic audio use cases.

Two people hearing the same event will perceive two different outcomes; the same person hearing two events will perceive two different outcomes. Perhaps there's nothing else to expect.

I'm exploring this topic on a forum concerned with such matters as well as audiophile switches, special ethernet cables, etc.

That was your first mistake! The "audiophile community" and MOST audio/audiophile websites are dominated by nonsense. This is one of the few scientific-rational resources.

Controlled Audio Blind Listening Tests (video)
What is a blind ABX test?

The "observations" and the "what this is not claiming" are contradictory. sorry. It is claiming networking has an impact on perceived sonic performance.... and I buy none of it. Nonsense.Whatever you claim to be hearing has zero to do with the network. I. am sick of such claims.

Every environment is different. Changes in grounding and RF pickup can have audible consequences. In my case I changed CAT6 cable between main switch and music room switch to fibre and did not find any differences. Though I am happy that I excluded one variable POTENTIALLY impacting sound.
