I have been moving some things around just to find out what will happen so may move my HD Plex LPS over to my router. I have a smaller ifi filtered power supply (I do not believe their power supplies/adaptors are linear but they are filtered) that I can use on the Gigafoilv4 and the ENO doesn't need power. I am currently using the HD Plex on the Gigafoilv4 because it is closest to my server. As mentioned, the results of any of this have been so subtle as to make me wonder whether there is any effect whatsoever.
Things that do make a noticeable difference include the upgrade I just made from a Mojo Audio EVO B4B21+ DAC to their EVO PRO DAC (a positive move - slightly better resolution and spatial information), and also I have compared running USB directly from my Mojo Audio Deja Vu server to the DAC vs. running Ethernet from the server to a separate Roon endpoint (either Metrum Ambre or Bricasti M5) and then AES/EBU or S/PDIF into the DAC. The USB sounds better (slightly richer, tonally bolder, and more dynamic) but the server uses the well-regarded JCAT USB CARD XE so maybe no surprise there.
