How to find and setup the best audio settings for alsa and pulseaudio

hi community,

i’ve a few questions about the optimal sound settings for my desktop. in this case i use the xfce spin. the used soundcard is a asus xonar essence stx 2. now i know fedora works here with pulseaudio and alsa but at this point i’ve no idea in which configurations files which settings for the best sound experience. how i can get the right informations about the technical specifications? 24bit with 192kHz. In the documentation about Pulseaudio but which from the 24bit LE or BE?! and the best settings for alsa too?
