Thanks for outlining your Ethernet setup. I say, enjoy your time with N200 until you’re ready to ‘tinker’ with Ethernet. Don’t know how long is your Blue Jeans Cat 8 cable run is? If it’s a shorter run like under 2M, then I recommended trying the ENO or Muon streaming system which comes with their excellent LAN cables on both ends for most bang for your buck. If you’re using a longer run then keep the BJ Cat 8 and just get the ENO filter which comes standard with a captive pig tail LAN cable for streamer end. The market is flooded with inexpensive noise suppression alternatives so try and compare them at your will…IME, most serve as band aids and doesn’t quite measure up to a much superior noise filtering solution like ENO or Muon.
