The WiiM Pro gives a solid sound and you can connect with an RJ45 network cable or WiFi.
I combine the Pro with a WiiM Mini in multiroom mode, I also have a WiiM remote control. Which is connected to the sub.
I currently have the Mini connected as a Sub, this is the Mini because. On the main, Pro I have my alarms & preference choices & number 1 to four on the remote control, set. Now I can set both the preference choices of the Main and the volume of the Sub.
On the main I have a speaker set with remote control connected.
When you connect the WiiM remote control to the Main, you set the volume on the entire Multiroom which is inconvenient for me.
