So I just purchased some AD700s to replace my Razer Carcharias and I like the sound so far, but I had a couple questions that hopefully some more experienced users could answer.
 
So I mainly play video games with my headphones (Specifically Counterstrike: GO right now), and decided on the AD700s because of its alleged sound stage. My question though is what settings are best to set my system to? I have looked around a couple different places saying different things and I have tried a bunch of different combinations and I'm not sure which one works best and allows for the full use of the sound stage.
 
I have a Sound Blaster X-Fi Fatal1ty Professional Sound Card (Similar to this) As of this moment, I have headphones selected in my creative control panel. Should that be set to headphones? Also, what should my windows speakers configuration be set to? I tried 5.1 but it sounded a bit odd in counterstrike, which brings a third element to the picture. CS:GO has an option of headphones, 2 speakers, 4 speakers, and 5.1 surround. Should I set that to 5.1 if my windows configuration is set to 5.1? Or is it best just to leave everything at stereo? I just didn't know if I would get less of the effect of the sound stage if I used conflicting speaker settings.
 
Sorry for my noobness and questions, I just feel like I'm not getting the full effect of the headphones. Any help would be appreciated. Thanks guys.
