Helo @astev1968,
So far the Switch X is sounding very good.
I feed both of my audio systems off of the 'clean side' of the SwitchX which is also a modem. this 'clean side' also feeds Wifi X. You need it to be able to control any app based server (Roon). Prior I was using a JCAT M12 with SJ LPS which is also excellent, but does not address noise on your local network.
I have never used AppleTVX; not a videophile...maybe I should. I think the AppleX has the Dejitterit power supply common to the Switch and Wifi.
So far I think the SwitchX sounds better. It is not a fast or easy A/B comparison as I need to rewire a few cables in my office and then reboot my Core (Grimm MU1) and or reboot the Wifi X. so about 10 minutes minimum to change over.
I will do this, but now just exploring the sound of SwitchX and testing the limits of my wifi control w WifiX.
No extra boxes needed. The WifiX comes with modules that allow my RJ45 LAN cables to directly plug in. The Switch is every bit a simple as any switch with a separate power supply. Port 4 is for feed from existing Modem. Ports 5-8 are the clean side. There is an additional RJ45 port for the WifiX
What is extra is the separate wifi X router. It has its own Dejitterit PS and you just plug it in and it boots up and works like any separate wifi router.
So now you have your regular home wifi for everything else (dirty side). You don't even need to hook any of those wires up to Switch X, just leave them on your existing modem or switch, but there are three ports available. And you need to connect one (ipad) control device to the clean wifi.
