The answer is hereUuh, … guys? Need your help.
Where have you read that ‘LAN itself… by specs… is transformer coupled?‘
It‘s been a while since I read the IEEE 802.3* . Last time when the IEC 60950 changed into IEC 62368.
And maybe I‘ve missed something…
But I really can’t remember something about fully transformer, galvanic, optical or whatever
(de-)coupled.
There are additional network adapters and of course router, switches, repeater even network cards implementing these IEC standards.
But that’s mostly about surge protection and the newer one about grounding or at least significantly more detailed.
Maybe you missread the IEC 60601? Which discribes additional network isolators among other things.
It also would baffle active LAN and PoE.
Or you have gear which additionally features galvanic coupling?
A premium router?
Our PC/Laptop mainboard LAN doesn‘t have.
And no streamer I have opened to date.
Don’t want to talk about this thing is snake oil or opens audiophile heaven.
That everyone’s own decision/experience or maybe …fun?!
But … it’s a good idea to mention:
‚please avoid mechanical stress on your device‘ or something like this.
At least for ifi‘s insurance.
If you are a vintage hifi fan, the latest state of the art stuff purchaser, a frantic digital believer, an enthusiastic snail oil tester, a Stax, ZMF, Beats or Grado fan,
or beware …just a music listener:
Enjoy your music!
