Ethernet cable for Streaming

Thanks to all for the help. I am now considering two options, direct longer cable from router to streamer, or use of a WIfi extender with shorter cable. Either way I am now considering using a Supra CAT8 cable. More expensive but with better shielding and connectors. 

@akg_ca Thanks for the detailed response. You have me rethinking the long cable approach.  What extender can you recommend? With as of yet limited research I identified a RangeXTD which can be purchased for ~$50.  Might there be better options?

CAT 8 has the best shielding and I believe maybe tighter twists - read about it here.You can also make the bulk of your run using fiber for a small cost.  Two converters like these and 45-50 feet of fiber with very short CAT 8 runs at either end.
I run 45 feet of fiber and also have 45 feet of CAT 8 in the same run that I was using before the fiber.  I have compared directly and hear virtually no difference - maybe a touch smoother with the fiber, but I could be imagining it.

Reading this thread with interest. Especially the post quoted above. 

My listening room adjoins the room where my ISP router (modem) sits, feeding my TP Link Archer router. My router feeds a TP Link switch feeding a lot of items such as TV, Sonos speakers, Phillips Hue Bridge, Blu-ray player TV box. So, a few noisy walk warts, and other electrical noise potential. 

I've taken a direct feed/run of 15m of shielded Cat6a from my router, in to the adjoining listening room to feed my Bluesound Node; would it be beneficial to cut out any electric/RF noise from the TV room etc, by breaking the run of Cat6a, doing as suggested above and introduce a short length of Optic cable between 2 converters, and reintroducing a short run of regular ethernet cable, probably Cat8? 

Thanks for reading

That is how I started, with a short run of fiber at the end.  Consider the CAT cables are susceptible to picking up EMI/RFI and the fiber is not.  Why not just run the whole 15M as fiber with a very short CAT cable of your choosing from the second converter to your streamer/server?  That is how I ended up - with the long run in fiber.  Consider buying a LPS for (at least) the last converter instead of using the wall wart.  Some report benefits from using LPSs on both converters and the router, which is what I have done. Also, make sure you purchase the correct fiber cable that matches the connections on whichever converters you purchase.  Good luck.

Well, I decided to install the Monoprice CAT8 50' cable. Seems to be well constructed, having Al foil shield around each of the 4 wire pairs and a braided shield around these. Quality terminations.

 If any issues arise I will go the WiFi extender route.

Thanks for all the advice.
