i'm a gmx user and been using it near to 2 years and i dont find its for techno heads. i think most probably it depends on the sound card. b4 that i played with my friends audigy 2 and its kindda blur and boomy, then i bought myself a auiotrack optoplay. it has more details la and the bass its not that boomy. my sub is set to 11o clock.

anyway i stuff some socks into the port hole so i can get a more tight bass and it works la. at least tighter than b4.
