Fiber or Eithenet

@tkrtrb125 - Thanks for the recommendation.  I'm using a Sonore Optical Module today right in front of my DAC.  I guess I'm asking if I should convert to fiber at my switch next to my router, run 50 feet of fiber and convert to ethernet just in front of my DAC or run 50' of ethernet and convert to fiber and then back to ethernet just in front of my DAC. Is there a SQ advantage to one?  

@testrun I am running the Sonore Optical Modules also and had a 75 foot run to my listening room. Pulled all the CAT5 out and ran with CAT8. During covid said the hell with it, pulled OC Fiber and the difference was night and day. Also people are recommending CAT8 cable and it is shield tied at both ends. I prefer CAT8 but use Telegartner unshielded RJ45 connectors as a drain so I am not getting any RFI/EMI from the cable and the drain direction is going away from the switch   . https://www.telegaertner.com/en/online-catalogue-datavoice-office/modular-plugs. in my entire network for my listening room I may have 6 meters of CAT8 from my cascaded switches to my Sonore OM. Hope this helps. You can PM me with any other questions on my setup.

@tkrtrb125 

just to be clear you much preferred Ethernet (cat8) over fiber for your long run and the a short run of fiber to clean it up.  

It should not matter what is before the optical cable.

So are you suggesting running all fiber if possible?
