What about wall plate connections?

I understand now what you are trying to do. There are couple of ways to keep your Muon Ethernet cable. You can buy a cheap Ethernet coupler (may degrade the sound) or buy a Ethernet Isolator.

Alternatively, you can go direct into Muon filter with Supra. I believe Rich mentioned  to me that the LAN after Muon / ENO filter is more impactful than the one before entering the filter assembly.

MUON / ENO Filter: open RJ 45  terminal.

MION / ENO FILTER  SYSTEM comes with extra gucci Ethernet cable to complete ’ the improvement.

so I Do want at to use this Muon male- male cable.

I am aware of the 200 Network Acoustics Ethernet couplers.  I need two at the switch end.

i really should have gotten female - fealr Supra Wired’s,  but don’t see them factory terminated.   For all I do I should make my own!

 Thanks, Ken

Well, I don't know how cheap they are but if you are going with that you should include a shielded jack. The female connector has a metal jacket instead of plastic to maintain the integrity of the shield.

Can you point me?

thanks!

I decided to just go ahead and use a JCAT coupler.  Easy to pop out the cheap wall plate part and ran the Supra cable through the wall (on both ends).
