Hi @mgrif104
Exactly. The Switch X creates an entirely new network in your home called 'Clean Network". You have to reboot your Roon core once connected, then your audio is only available on this clean side or clean network. As such, ipads etc on your existing home wifi will not see the clean side. So the WifiX handles this by creating wifi on the clean network. I use my ipad, select the 'clean Wifi' and control my music. I can easily jump from clean wifi to home wifi when needed, or I just cheat a little bit and use the same ipad on clean wifi to read my book or check messages.
The SwitchX and WifiX are sort of a necessary package, unless you control your digital audio by touching the streamer.
For perfection, this audio ipad would do NOTHING except control your audio. We all know Apple devices like to chatter a bit and all of it cannot be turned off. I think a we bit of internet usage on the clean wifi is negligible to the sound. Chris at Dejitterit explains that the WifiX is intentionally controlled is scope so as to not pollute the audio stream
