@antigrunge2 . I'm going through the same. I think my USB is pretty good, but I'm still seeing some digital noise (apparent mostly in sibilance), so am focusing now on ethernet stage.
I've tried Eno, and cheap fiber bridge, but both too analytical.
So, I've bought an iFi iPower Elite for my Netgear Orbi Satellite - it's the only viable route open to me. And have a Sotm dbl-cat7u cable on order. Their cables, by consensus, seem to offer the best bet of de-digitalising the sound. And once I have a decent cable in place I'm hoping to try either the EtherRegen or a decent fiber setup.
