The assembly provides its high-quality music. Including in the bass. No doubt the A5 + Are most interesting for home theater. But for music, P4 are better! It there's less bass, the sound is clearer.
I am VERY pleased.
Speakers: super
Amp: great. One can even play source 1 and source 2 together (no need to press a button to switch from one to the other)
DAC: the computer is more rotten, more changes everything! With that the sound is good, very good, certainly better than almost everywhere you go.
For the DAC, if you use linux you will need a "sound server" as "pulseaudio" (it is installed by default on most distributions). Indeed, the DAC sound card supports only one source at a time (= not possible to output audio simultaneously in two different software).
