I would like to add my comments.
I am also using a EtherRegen. But I have the ethernet cable running from my modem to the EtherRegen,
From the EtherRegen I am then using fiber cable to my Lumin X1 which accepts fiber directly.
From the modem I was using a cat 6 cable, but recently switched to cat 8 and you know what? I did hear an improvement. It provided a more solid soundstage. No doubt about it.
So, I just ordered a WW Platinum 8 cat cable, so I’ll see where this leads.
