Dunno if you still have the mixamp or not, but you could put one speaker from your current 2.0 setup on each side of you, and use the mixamp for dolby headphone, lol. I did this with my Def Tech HTIB Sats (for S&G's) and was pleasantly surprised with how well it worked. Of course it wasn't good enough to replace the 5.1 setup or the Mixamp + Headphones, but it was pretty ok for gaming the little bit I tried it.
