Help optimizing my streaming setup

My modem is 15m from my system.

I found a network switch made a difference. Bought a Cisco 8 ports unmanaged switch and had Fidelity Audio (UK) install one of their clocks.

Put my modem and switch on a linear power supply.

And bought reasonable ethernet cables. Triode Wire Labs Freedom from wall to switch, and another from the switch to the streamer, with a couple of LAN Isolators.

The uptone Ether regen is excellent also just plug Ethernet cable in to it then on other side your best Ethernet cable and it’s clean of all digital noise 

many great reviews.

Fiber optic cable just before the streamer. Use a tx and rcvr box then a good Ethernet to the streamer. This will effectively take all the noise out of the Ethernet connection from the router. An amazingly cheap upgrade that is very incredibly effective and noticeable!

I use the etherregen switch and am very happy with it.   there are quite a few of the used out there (new production is halted for an upgrade).  

A member on audiophile style recommended this. He explained only using one (just before the streamer) worked better than two (one at each end of the cable run). Very cheap, and he said it works well. I have yet to try it. @jerryg123 that converter looks like a good way to go!
