Hi Eric, I hope you have a good week end.
My theory is „Everything Matters“. So the LRS01-E1000/POE was tried, and the results are way better than I hoped – I just took it out (after reading your post) and put an LAN-LAN adapter instead. OMG that sounds BAD. You can also read https://theaudiostandard.net/thread/7889/cyld05f-power-supply-ethernet-network. People say the same about the LRS01-E1000/POE!
I don´t care if there is another item in the audio chain, as long as it sounds good/better (for you to try Billie Eilish „Billy Bossa Nova“, on this track you hear the things I mentioned earlier, lack of bass pre 902 and pre RS01-E1000/POE).
The Stack Audio opens up the soundstage, gives more details, more air, more fun, more music. I also have some footers that in theory not make much of a difference. But they do, also under the Stack! And the Stack switch mode PSU for that one sounds better than a linear Allo Shanti PSU or powerbank – on this one!
I have no earth on the LRS01-E1000/POE yet, waiting for a longer cable.
Thanks for the long link with Ferrits theory 😀
