I currently have a set of Sennheiser HD590's and an X-Fi Xtrememusic, but no mic. I mostly play BF2. They sound pretty good with the 3D CMSS, but I am wondering if something like the Medusa 5.1's would sound better. Or would it be better to just get a Zalman Mic and add it to my current set up and maybe get a headphone amp? What amp do you guys recommend?
