In its simplest terms I want to be sure that I understand the Hifiberry DAC+ Pro and Hifiberry Amp2 boards. Is it accurate to say that this combination is somewhat analogous to a traditional separate consumer amp and preamp set up? In other words, I would need a RPi with an Amp2 HAT and a RPi with a DAC+ Pro to build a small system using both. I assume I’m right in my thinking that it’s not like you can add a DAC+ Pro HAT on top of an Amp2 HAT on the same Pi.
Probably a very naive set of questions/statements, but I’m just being honest and willing to put my ignorance out there I know I’m still missing the larger issue of how you even get these two things to talk to each other.
