What you might be hearing can be just expectation bias so always do some ABX first. IMHO, I don't really think oversampling can actually improve the music and if it did, it may be so subtle. And also, "the truest sound" can be very difficult and can be expensive to achieve, as it include, perhaps a studio-grade equipments to sound almost true.
You already violated TOS8 once; now twice. Please don't do it again.
Many technical points do not have logical answers when it comes to PC audio. Keep it simple, do what works best with your system and drivers. If possible use a direct mode like ASIO or WASAPI, IF it works well on your system.

You don't, because the Xonar drivers are not bypassing the windows mixer in WASAPI mode like they should. DS hooks into WASAPI as well, so it's unlikely there's a difference... if there is, you might be bypassing detrimental sound 'enhancement' settings in the xonar control panel.
