You really should try HeSuVi.

Its an excellent app that allows you to add Virtual surround. Big deal you say.
This allows you to try all of them Dolby Atmos, CMSS, Dolby Headphone, Direct Sound3D, GSX, Flux Hear, Razer Surround and loads more.
Also has an EQ should you require it.
Been fiddling with this for a while and its very impressive on my Asus Xonar Soundcard through optical connection to my Astros
