Wifi vs ethernet revisited

Hello OP and friends,  So interesting all the different ways to improve digital!  Good discussion.  I have gone to much effort to improve my digital front end.  Many have contributed ideas I have used:

Verizon Fios > Verizon Modem (with wifi disabled) Powered by Sean Jacobs LPS.

From this I run all ethernet feeds to non audio as well as Eero Pro 6 Mesh wifi (three units wired around house).  I also run short ethernet into JCAT M12 Gold Switch (also powered by Sean Jacobs LPS) this will feed only my two audio systems >

Short run into GTT DeJitterit Switch and Clean Modem.  So I have stacked two nice switches in line and found it further improves sound.  The DeJitterit Switch / Clean Modem creates  a separate 'CLEAN NETWORK' that only serves my audio systems.  From this 'Clean Side' I run a quality ethernet cable feed to each of my 2 streamers. I use no wall plate couplers, instead using JCAT ethernet couplers if needed.  I run my long cables through the wall plate to reduce couplings.

The GTT DeJitterit also comes with a 'Clean Wifi' Router, designed to be quiet and use minimal bandwidth, purely for Remote Roon or Streamer Access.

So I have eliminated all the other internet traffic from entering my clean music side of things. And thee is significant internet traffic on most of our homes!

Each and all of these things have enhanced my digital sound.  I have also demo'd the NA Tempus switch, and that is also nice.  But I owned the JCAT switch, which is very comparable, and then chose the GTT Dejitterit switch / clean modem as the best sound.

Also agree strongly with keeping all computer / wall warts etc away from audio and on different circuits.

Take care! 

Thanks @fastfreight you can see my thoughts above (and those of others) which are generally in line with yours. One thing I did not follow: if your baseline Verizon modem/router is generating two different LANs (for audio and non-audio) on the same subnet, can't you get Roon to discover across LANs and turn off the non-Eero wifi that you've mentioned? Maybe I am misunderstanding something about your topology.

Hi @debrajray ,  

 if your baseline Verizon modem/router is generating two different LANs (for audio and non-audio) on the same subnet, can't you get Roon to discover across LANs and turn off the non-Eero wifi that you've mentioned? 

So it may not have this  all correct but here goes: 

The Verizon Modem is only generating one LAN.  But the audio only feed, exiting the Verizon modem, is cleaned first by the JCAT switch, then it enter the DeJitterit unit.  Here the DeJitterit creates another wired LAN, and outputs to its included wifi router to spin off a separate wifi network so that I have control over my 2 streamers on this clean network.  My Roon core lives on my Grimm MU1, and it can only be seen on the clean network.  If I search for my Roon Core while on my main LAN, it is not seen.

This 'clean network' really improved my sound.  Taiko does something very similar.

@fastfreight yes, the clean network is a great idea but I'm trying to understand if it can be cleaned some more :-) Imagine that you threw out the verizon router and go straight from the ONT to a router that can generate two LANs on the same subnet. One LAN then goes to your switch system -> audio (which we can discuss later) but all wifi is disabled. The other LAN goes to Eero. The idea is to have your remote (say a phone) on the Eero mesh but still to be able to discover your other LAN where Roon lives. Isn't that even cleaner?  

@debrajray I am getting a headache!  I surely don't know.  but it seems to me that ANY additional traffic on the clean side is detrimental. Of course it is easy, say on my phone or laptop, to jump to cleanwifi to control my audio if my ipad is awol.

A Verizon compatible modem that can split out two LANs is interesting, but isn't that essentially what I have done?  Plus I do use wired outputs on the main non audio LAN to feed my TVs as well as the Eero units.

I certainly did not design my front end from the ground up, but implemented many improvements one at a time over years.  I read a good switch makes a big difference, tried it and found it to be true.  No skepticism from that point forward.  But I did find less expensive changes were harder to appreciate, including the Bonn 8 switch and the Ether Regen. Good power supplies for the modem and switches make a huge difference.
