Fiber optic cable
Emil:
Lurking over at the Audiogon forum where a discussion on whether Ethernet cables make a difference or not, someone suggest trying fiber optic cable instead. He states that electromagnetic interference and radio frequencies do not travel own fiber cable providing a noise free signal. He even provided what was needed.
You will need two ethernet cables and the following:
one cable

and 2 FMCs
https://www.amazon.com/dp/B0716XT1QT?psc=1&&ref=ppx_yo2ov_dt_b_product_details
about $60 total. Cheap
Connect one ethernet cable from internet source to one fiber media converter.Connect the fiber optic cable between the two FMCs and finally an ethernet cable from the 2nd FMC to streamer.
Well, for 60 bucks and amazon's easy return policy I gave it a shot.
Noise floor dropped like a rock. You dont think you have noise until its gone.
Black background, detail galore. Hate to use this cliche but I'm hearing things I've never heard before and all for 60 bucks!
If you want to improve upon that, add this power supply for $86

Too cheap to not to try, It would a sin not to :lol:

Yes this is true fiber optic is supposed to be immune from EMI and RFI. To my understanding glass fiber optic is better than plastic, but not as practical.
Also, whatever you do, streaming is never going to be as good as playing the file locally. Besides the fiber optic that you've introduced on your end consider the miles upon miles of signal that that audio data is traveling through which may be non-fiber optic just to get to your place.
Moreover, in a general sense adding more devices into the chain is going to make sound worse instead of making sound better.
All of the aforemention stated, if it's worked out for you and you're hearing a difference that's what matters. Also to your point, it's relatively inexpensive to try. :)

I ordered it we will see what happens. Seems since I have Fios fiber optic coming in its excessive conversion. Makes.more sense that tjis should go at the entry of the house like a booster.

let me know what you think.
And if it works out for you, there is a rabbit hole you can go down
