I'd like to replace my libreelec setup. Right now I'm using RPi2 and Allo sound system I've connected to 2 speakers. It's about 7 years old. What hardware do you recommend? RPi4? Which dac/amp?
Following the "if it works, don't fix it" principle an RPi4/5 board reusing the same Allo amp board would be a simple refresh. The CPU performance bump from RPi2 > RPi5 will be rather noticeable.
