Best Computer Speakers

I spend a lot of time at my computer for business purposes. I've started researching economical but satisfying speakers for my desktop through which I can enjoy streaming music. I've got Amarra sQ and HiFi. I'm thinking perhaps a pair of good powered speakers might be a perfectly good way to go.

I have read a little about Audioengine A2+ speakers. They look quite promising and may be perfect for my needs. Strictly nearfield listening.

Your thoughts and suggestions are most welcome.

Thank you.
Very satisfied with my: Audioengine N22 amplifier, Audioengine P4 Speakers on DS2 stands with Velodyne 8100X Subwoofer.
Thanks very much for all your helpful responses. There's a local Audioengine dealer which will make it easy for me to audition. I like the built-in amp and DAC. Keeping it simpleĀ….
Well it all depends on the size of room, the room you have available at your desk etc. I use some M-Audio BX5 and they're great for me. I didn't wanted to use a subwoofer because I get too much low frequency reflections in my room and it sounds boomy.
