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.
