Fiber or Eithenet

@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.

@yyzsantabarbara 

So are you suggesting running all fiber if possible?

No, just the "last mile" just before the DAC should be fibre. All the analog gremlins should not be able to travel in the glass fibre cable into your DAC.

Using all fibre would not hurt and maybe cheaper or easier. I do not know the costs. It is not something I am wanting to do but if I had the option, I likely would have chosen fibre.

I have Sonore Optical Rendu's for the final mile before the DACs. I used to own a Lumin X1 DAC that had a fibre input in the DAC. A great feature but I sold that DAC.
