I have concluded that the IQaudio DigiAMP+ will be perfect for my project. Although I see it needs an external power supply.
From reading the documentation I believe that this USB Type C 3.1 PD to 5.5mm Barrel Jack Cable - 1.2m long with E-Mark combined with USB C Plug, Anker USB C Charger should be suitable to power it.
If someone could make sure I am correct, it would be really appreciated
