Ethernet cables

They absolutely make a difference and the ones that I have had the best results with are Wireworld, especially the red starlitght 8 and my reference the Platinum (my favorite). The build quality is second to none and believe it or not (and I wasn’t a believer) they make a big difference in sound, just like interconnects. Highly recommend. Would I spend a huge amount of money? Maybe not, but these are very reasonably priced and I’m comfortable at this level for the results that I’m getting.

@coachpoconnor check the link I posted. Tons of data out there if you’re willing to do your research. 

My attitude towards cables, particularly digital ones, is to go one step up from the basement, but not to go into the stratosphere 

They absolutely make a difference and as mentioned should be commensurate in quality to the rest of your system. The "zeros and ones" argument is a false one because the issue is with noise on the line - if not removed - will travel to downstream and present both noise and timing errors for the streamer and DAC to cope with.

Ditto the first answer.

Triode Wire Labs freedom. I have two, one from extender to optical isolation and a very short one from switch to streamer. It gets complicated but it all makes significant improvements.
