Router Ethernet Cable to Streamer


In my house, the wifi router is 25 feet away from my components. I plan running cat8 underneath the base board as hiding cable above or below room, side walls, exterior cable are not options. Picked a relatively cheap cable to try out first.

Cat 8 Ethernet Cable 30 ft, 26AWG Nylon Braided High Speed Heavy Duty ... https://www.amazon.com/dp/B089B2YP77/ref=cm_sw_r_sms_api_glt_fabc_TJA5SW4HNFZ0F14K8WVA

Is it possible to decrease potential electrical noise introduced by the AT&T wifi router with a better router next in the chain? If so, any recommendations? Also, has anyone had success/noticed a discernible difference in SQ by introducing something such as a LAN isolator right before the streaming source? Any constructive feedback or request for additional applicable situational information is welcome. Thanks.

I did put an EMO Systems EN70HD inline just before my Auralic Aries G1. I had not experienced any noise before inserting it, and I did not experience any noise afterwards. I kept it inline for it surge protection -- I consider it cheap insurance. It may well make a difference if your Ethernet runs close to power lines or other nose sources.

Versions of this discussion can be found on this forum and the recommendations are all over the place so you may want to do a search.  Like @ozzy, my longest run (15M) from my router is fiber using TP Link converters and short runs of CAT 8 at the ends.  I will add that you should take a look at the LC vs. SC versions of fiber cable and connectors since the LC is quite a bit smaller and just as good for what you are doing, if the size of the cable/connectors matters to you. Also, the dual connectors come apart if you need to route them through small holes.  However, the converter jacks must match the cable you use.  Last thing, there are more than a few here who believe Ethernet cable is a better option and others who don’t think  it matters.
