Today I've tested the most direct network path available by hooking up the music server in my living room and bypassing the FMC's: music server (powered by a non dedicated AC outlet) -> AQ Diamond ethernet -> sMS-200. The music server also had the primary NIC connected to the network as I temporarily used the network connection that goes to my streamer PC. It even has a EMO Systems EN-HD70 LAN isolator inline.
I really had to A/B test this multiple times but could not reliably tell a difference, in fact if anything it sounded a bit worse so I'm back to the previous setup with the music server upstairs and the 2 FMC's and 20m fiber optic cable in between. The FMC closest to the sMS-200 is powered by my Hynes PSU. This may explain why both Romaz and I don't hear a clear difference but others using lesser PSU's do, not sure of course, just guessing here.
One more thing to do/try now is connect the EMO Systems EN-HD70 LAN isolator inline in between the ethernet cable from my music server to the FMC and power the FMC there not using the supplied SMPS walwart but the 'el cheapo' linear PSU I still have but currently not in use anywhere. This too is rather counter intuitive since both are used before the fiber optic cable but easy enough to try.
