@clive101 Thanks. Yes, once you start this route, it is a rabbit hole but you will find the journey very revealing, exciting (with some frustrations and hiccups in between) but will get you were you want.
I have tried etheregen, sotm, English electric, ubiquiti network switches in my system, individually and in all combinations of 2 and 3s (including the sequence in which they are in series). My take and for my taste, more the switches in chain, lesser the noise but there are some changes in musicality which I did not like it. I ended up just using sotm (Router to ubiquiti switch > sotm via fiber > streamer via ethernet). Still, in digital chain, fiber optic and network switch (of your choice and taste) gets best out of your system. Of course, I have seen people using multiple switches in chain, but it is not my preference.
