My iPad is about 4 years old and I have iPhone 11.
So, I can use either iPad or iPhone to control the music? Then, the connection between iPhone and Node is through WiFi, right?
If I use a direct network connection, do I still use iPhone to control the music? Well, things will get cleared once I get a Node.
Once you get the Node you will control it/music via phone and yes over network. Music will stream directly to Node over your wifi and you control what it streams via an app on the ipad/phone.
If you have an ipad with with a USB C connector you could use the Qobuz app on the ipad to stream directly to the USB B input on the Oppo. Dont even need a node.
On the iphone 11 or iPad with a lighting port you can use an apple usb lighting to digital camera adapter. This adapter has a usb c port on it. You then connect a USB cable that has USB C to USB B. The USB B plugs into oppo.
This effectively sends a digital signal from you phone/iPAD to the Oppo allowing you to stream up to 24/196 Khz (high rez) Directly to the Oppo from the Qobuz app on your phone. You can even download the physical files from Qobuz to your device and play them from there. I have actually done this.
Maybe not a long term solution but for less than a $75 you can do a free Qobuz trial and I think you be surprised how good it can sound.
If you interested you can contact me directly and I can walk you though it.
Camer adapter for iphone/iPAD
Here is what mine looks like. This adapter only has the lighting to USB A connector. Then the USB A to USB B cord.
