Thank you, will try it wirelessly also!

Hi @floriz01 welcome to the 'fun'.  Give it a try just to see how things work and at some place you need to use a WIFI point but i try to limit my 'reliance' on the WIFI.
I don't do much streaming from online services but that will increase your reliance on the wif network.  So some of what i suggest might not be as simple if you want or need to use streaming services.

A simple AP point with your Devialet client is best.  Take an old router with a WIFI and plug your speakers into it, setup its own network, and plug the WAN side of that router into your current network.  That will pretty much isolate your speakers on its own network, with internet access, and you use that WIFI access point to connect to and control or feed the speakers.

I do this but i also use that router for other devices i want to keep isolated from some other private network.
then I use an old android phone that pretty much just runs only as a Devialet control , remote point.

If you use your phone and you are roaming around a mesh network then your client gets passed around and confuses the simple minded speakers network stack who has it..

Use Ethernet avoid WIFI for the speaker to speaker connection.
Use a nearby WIFI AP on the same network segment( use a old router or take an AP and plug it into the same network switch your speakers are plugged int).
Once configured i use the ethernet to control the speakers via a custom windows client. (http://halrad.com, its rough but works).
I leave my phone client connected but rarely use it other than to connect (join or leave) two systems together for 'multi-room' use case. (via the android or ios client)
Sources (Dialog or Arch) are selected via my app/system. (i only use these two most of the time)
The dialog and or arch is fed from whatever is desired.
Volume is controlled via the volume remote or my app/system or a phone/tablet devialet client.

biggest complaint is every time you reboot your speakers.
I recommend doing this weekly.
the source IDs change..   if you use the devialet client app you dont care, if you use my app you have to learn the new index for the source you want. (i use optical which is hard to pick them apart, have to do it via Device ID,  in the current sources list) but you dont care about that unless you are a dev.

point is: use ethernet as much as possible.
keep it simple.
stay away from all of the fancy mesh stuff.
use an old router and AP if you have one , it might make your life easier..

 good luck, let us know how it goes....!!!
 lots of people have hit issues, i doubt you have 2 bad speakers in a row.!
