Much would depend on how close you will be to the speakers.
If you are looking for something on the desktop and your listening distance is less than 5 feet, something like a powered monitoring system like the Genelec or similar may work best.
Across the room and passive, the KEF LS50 or the new Sierra 2 would be a good start. You may not have thought about it, but what type of sound do you like from the midrange? A metal cone sounds different than paper. I prefer paper generally; sounds more 'alive' to me.
