Headphones

Hello everyone.. I don't know if I'm in the right subreddit but help would be really appreciated. I see in this forum a lot of recommendations on getting certain headphones and DAC/AMPs and so on. I'm now able to start getting better stuff for myself and for my pc and gaming I got a PC38x as I've seen it is a good headset..

I got in my PC a Soundblaster Z sound card (it is not DAC/AMP) and I've been using the SBX profile for allI do.. I don't know if I have been wasting audio quality or anything using these settings. I don't really know much of EQ or whatever.

I've tried without it and it seems audio is a little low.. I know everyone says these headphones can be driven without AMPs but it seems fairly low to me.... unless I crank the volume knob up in which sounds very loud xD

Anyways.. I even tried Dolby Atmos to attempt get better sound... positioning or whatever.... but what I don't want to do is to get used to bad equalizing or bad audio because of me using software or whatever.. how do I know that I'm getting good audio as it is expected?

So... what is the recommendation? should I keep using my soundcard? is SBX profiles good and what can I get recommended?... is raw audio better?...

I'm just.. confused
