Home network Fibre optic vs Ethernet

I have both Ethernet (CAT8) and fiber running from my router 45 feet to my system.  I have compared the sound from those two options multiple times and I have used a variety of filters as well as linear power supplies on all the FMCs and peripherals, and after all that I still could not reliably discern a sonic difference between the two.  I decided to stick with Ethernet because it is simpler without the need for the converters.  I do run the Ethernet into a switch that is near my system and from there into the Network Acoustics muon filter then into my server.  My suggestion is to keep it simple and not overthink it, either option should work fine.

Thanks @mitch2 thats great to hear. 

If you have this opportunity please do your audio system a favor go with fiber!

I like the suggestion to run both and use ethernet for now.  Right now fiber has one vendor with a loyal group of followers but I (and many others) aren't convinced that the losses from the dual converters outweigh the gains.

but I'm open minded, and technology changes and it doesn't cost much to run the fiber so have it there for the future.  In 5 years we may all be running fiber.

I would also run both.    I use a ethernet switch with SFP fiber ports and a media converter to isolate my Aurender in my main room.  In my second system I use a pair of media converters to isolate my Vault 2i.   

I also don't think you hear a difference but I wanted to isolate my gear and this was an inexpensive solution.
