10 x 10 is a pretty small space. I wouldn't recommend Klipsch horns or big panels, you're just going to overload the room, or compromise the speakers and get poor sound. I think you'll be best off with a two-way monitor. I'm unsure if Vapor Audio ships worldwide, but if they do, buy a Cirrus. If not, there are plenty of other good two-ways - Monitor Audio PL-100, Dynaudio Confidence C1, Usher Be-718, Volent VL-2, KEF 201/2, Merlin TSM, etc. I'm sure you can find one you like.
Connect your computer to an asynchronous USB DAC like the Ayre QB-9, and then use a nice integrated amplifier like a Primare, or Simaudio. You should also consider some type of room treatment, spaces that small and especially square spaces can be just a nightmare in terms of acoustics. Ceiling and wall diffusors and some bass traps can help your room sound larger than it is.
