Which one will give me best sound quality? A gpio DAC or an external usb soundcard?
I want it to connect to my car´s amplifier, so I need RCA or minijack connections, not optical or hdmi...

The 'stereo' socket delivers the equivalent of about 6bit (rather than 16 bit) and all USB devices suffer 'drop outs' == the Pi SoC has ONE SINGLE USB port so all USB and Ethernet activity has to 'fight' for the single set of i/o wires .. which leads to many dropped and repeated packets ... which only a keyboard / mouse or USB sound device is going to notice ..
