Can't tell you a thing about the speakers listed, sorry.

What price range are you in? What is the room size? Are these party speakers or for critical listening? Will they be placed very close to your listening position (nearfield)? What have you heard so far that you liked/disliked?

BTW, you'll need powered monitors if you plan on hooking this up to your computer. In which case, I'd look at Genelec.
