its definitely a rabbit hole of reading but many many folks have done great experiments which allows us to make some shortcuts on choices. X router worked well for me, WiFi to that before the network switch provided some isolation LPS and cables make a good difference too.
a very visual thread is here:

Hi HT,
Glad you’re having fun. I’ve heard the expression rabbit hole applied many times to network tuning but in fact it really isn’t, as it follows the exact same logic as the rest of your hi-fi system. Let me explain
Lets say your Network is like mine and comprises a modem, a router, a wi-fi to ethernet bridge, a switch or two and a server, all to deliver remote files to a DAC.
I have found that, like other hi-fi components the following improvements to the network will increase sound quality, sometimes by jaw-dropping increments:
* Quality of power supply….specifically supply impedance, noise and ripple
* DC cable quality
* Resonance control
* Ethernet cable quality
* Cable screening
As far as my experience goes, there’s a logic to how the above network elements and their improvements are arranged.
First, imagine I upgrade the power supply to the modem. What I hear is a fairly major step up in sound quality. This has 2 major implications. An improvement right at the start of the chain has the ability to ripple right through the entire string of network components to be heard as a sound quality improvement at the other end of the chain. What that means is that the improved output of the modem improves the input to the router, which improves its output, which improves the input to the bridge and so on…..so what we can say from this is; “the better the input, the better the output”…..so every time we improve any input of a module we improve both the inputs and outputs of all downstream modules. This has a second implication….Your network not only provides the means to move music files from one place to another….it also provides a mechanism for cleaning up and improving the data stream…..to the point that your network may be the most important, comprehensive and cost effective means to improve SQ in your entire system BUT there’s a major consideration
here. In the same way that a better input improves output, it works just the same way in reverse….the worse the input, the worse the output. Let’s say you have 3 oscillators in your network stream with accuracies of 10ppm, 1ppm and 10 ppb…….depending on the order in which they are arranged, your timing accuracy will depend on the last clock in line. If it happens to be 10ppb, great, but if it happens to be 1 or 10ppm, you’ve failed to gain the maximum improvement . Same applies for cables….same for anti resonance measures and all the other improvements. Ideally to get the most bang for your buck, your bit stream needs to constantly encounter increasingly better specifications, so your bit stream is constantly cleaned, refined and improved on its journey through your network. That way you don't send a 10ppb bit stream into a 1ppm device.
In my system I have standardised on single manufacturers for power supplies, cables, DC cables, resonance control devices etc. In that way I can be certain that the bitstream is improved at each successive module, in a similar way to compounding interest, so the improvements I make at the modem improve the input and therefore the output of the router and on through every downstream device. Every single improvement in the early stream is compounded by all the other components. The nice thing about this strategy is that it can be done gradually as budget allows….the important thing is that you have a plan and know what to add and where. In my system I know pretty much all the improvements I could make….
Upgrade LPSs with ARC6 capacitor boards, starting at the last PS and working back
Upgrade LPS fuses, again starting at the last LPS
Improve the last Ethernet and USB cable to Synergistic Research Galileo SXs
Add an active grounding device to the star earth of all system cable screens
The only one I’d need to trial would be the fuses because at the moment all the fuses are stock and Ive no idea what other fuses deliver. When you standardise on anything you have to be very sure that the devices are neutral, otherwise the addition of multiple units will start to add a distinct character to the sound. The characteristics you want are neutrality, purity and resolution….usually achieved by noise reduction in its various guises, resonance control and of course great product design.
