Hi,
I have recently setup the BOSS DAC v1.2 the output to my speaker via an external "Volt+ with Stepped Attenuator". I am planning to buy another "Kali + Piano 2.1" bundle when it become available again just to have another taste of the output quality.
However, i was wondering if I can plug the BOSS DAC with the "Kali + Piano 2.1" bundle into the same Pi4 via a GPIO expansion board as attached. The playback option will be selected using the Volumio software. I would prefer to have this kind of setup so that i don't have to use 2 Pi Board.
Thank you for the advice.
