Just curious but is only the one dac used in my setup.
Source is an Andriod tablet with large micro SDcard (128GB; soon be upgraded as nearly full).
Sound apps are PowerAmp playing FLACs from SD card, BBC Sounds and Qobuz standard.
Tablet Google Home app casting via wifi to built in CCA in Onkyo RX 8270; 8270 ethernet wired to router. 8270 has an AK4438 dac chip.
So I am guessing that digital data, from all three source apps, is sent to Onkyo's CCA then onto the AK4438 then through the analogue side of the receiver?
