I will try your suggestion and see which works best.
Thanks!

No, you can connect it either way...ER is bi-directional, as is "the moat".

This is the correct guidance as provided by the manual originally written by Alex and John.
However....Emile Bok of Taiko has found that connecting "servers" on A-side and going out to the "destination device" (e.g. a Lumin, for example) via fiber, also on A-side, can, in some systems, sound better than going out via "B-side".
And, in fact, that's what I've also found, as well, in an experiment I did just last week.
Here's what I did:
a) The Mac Mini Roon Core is in a "remote server room", next to my home network's Pace router; the Pace router has 4 plastic RJ45 jacks on it. Previously, I had the Mac Mini and EtherREGEN each connected one of these plastic RJ45 jacks with Shunyata Sigma Ethernet cables. The Sigma that came "out" of the Pace router when into B-side of ER and out via LC/LC optical fiber on A-side to the Lumin P1 in the main rack in the living room.
b) Based on Emile's findings that A-side of ER can deliver really "clean" signal, last week I connected my Mac Mini's Sigma Ether to one of the RJ45 jacks on ER
instead of to the Pace router, and...lo and behold, it sounded
quite a bit better. In this configuration, I had the Pace router connecting to ER via...
B-side.
c) I then tried connecting the Mac Mini's Ether via B-side, but it didn't sound as good as when connected on A-side, and the Pace router connected via B-side.
d) Given, that I then connected the Pace router's Ethernet cable to A-side as well, but that sounded the worst.
So, now my set-up is: Pace Router -> Sigma Ether->
B-side of ER. Mac Mini-> Sigma Ether ->
A side of ER. ER -> LC/LC fiber to the P1.
My hypothesis as to why this sounds best is that the "moat" between A/B sides is preventing all the crap from the el-cheapo Pace router and it's chees-y plastic jacks from getting through to A-side on ER. And...connecting the Roon Core to a quality RJ45 jack with 12 isolation transformers/jack is better than...connecting via chees-y plastic jacks on a Pace router.
Funny how that works...
