Ethernet cables

You have a wall plate and from there you connect to streamer…is that right?

Here’s something to try then…

iFi LAN iSilencer to the wall plate, then a short run of a good Ethernet cable from the iFi to your streamer. Pick whatever Ethernet cable you want to try but I wouldn’t spend a ton on it. 

@lovehifi22 I have mine plugged into EERO access point. Then Purist Audio Cat7 from Silencer into Aurender N200. I’ll be honest I could barely hear any difference with and without the iFi unit in the chain. Tried it into the Aurender as well. I figured cleaning up the signal right at the EERO output made most sense to me. Keep in mind the results will vary based on how good the Ethernet implementation is in your streamer. Aurender happens to have a solid isolated implementation and I attribute the very negligible change to this. I never tried using two Silencers since the results with one were barely, if at all, audible. I left in because 1) it’s not expensive and 2) it did no harm. But again, pretty sure the results will vary in each installation. Try one first. You can return it if it doesn’t work.
I also second @lalitk on LinkUp cable recommendation. Excellent cable that’s solidly built and doesn’t cost an arm and a leg. I have this cable and can say it’s a bargain. Not as detailed and lively sounding as the Purist but also not as expensive. 

Good decision. I think the Supra and LinkUp will be close. I tried Supra in both the regular original termination and the one upgraded with telegartner connectors. And both performed well. 
 

But you absolutely cannot apply analog audio logic to digital anything. It’s important to understand how these things work well enough to focus on the things you can affect. Network switches, cables, regenerators, eh, if you don’t hear dropouts, the data is getting there.
 

@jji666 digital signal is carried by analog signal in the case of copper Ethernet cables. And because of it there’s a good chance that your Ethernet cable is susceptible to RFI and EMI injecting garbage. You will have different streamers dealing with this differently. You really have to look into and understand how this interface is implemented. Digital signal going into the streamer gets then processed and converted to a signal the DAC will understand. That’s the other part of the streamer design. Then, depending on the interface you choose to use between your streamer and your DAC, what will impact the final result is the clock in the streamer, if you use SPDIF output, or the USB processing and clock in your DAC if you’re using USB interface. You can simplify it all you want and say it’s all 1s and 0s, but it doesn’t change the fact that Ethernet cables matter (less so with a very solid streamer implementation), and streamers matter as much as the DAC. 
I do agree though on components first approach. I wouldn’t be buying a $2,000 Ethernet cable hoping that it will make a $500 streamer sound amazing. 

@classicrockfan just so you know…

In the case of copper cables, data is transmitted through electrical signals. The cable consists of twisted pairs of copper wires, with each pair carrying a different signal. These signals are encoded using a technique called pulse amplitude modulation (PAM), where different voltage levels represent different bits of data. The electrical signals travel through the copper wires, and the receiving device decodes them to retrieve the original data.

Because this is an electrical signal (it’s voltage) which is the same as your signal interconnects, it is susceptible to the same elements (RFI and EMI) as your analog signal because essentially it is an analog signal. Go crawl back under your classic rock again and stay there.
