Everything matters. It sounds like my set up is at least in the ballpark of the OP @lnitm
I use a Triode wire labs freedom ethernet cable > small green computer isolation bundle with LPS > LHY-SW10 > a very short freedom ethernet cable > streamer. The LHY-SW10 is also connected to an external clock. Details of the whole system can be found in my house of stereo.
It might be of interest if the ifi experiment is unsatisfactory. I kind of miss the journey part of it all. It's every audiophile's goal to get to a point where the sound you achieve is everything you always hoped for, but once there, while I love the sound immensely, I do find I miss the journey.
Enjoy the journey!
