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.
ps
I have a pair of Mirage OMD-5's powered by an Audioengine N22 integrated amp on my desktop, and an M&K MX70B subwoofer under the desk. My source is Roon on my desktop and an iDSD dac.  The sound is excellent and the omni-directional OMD-5's play the largest role in that.  


How much does the B &W  A 7 cost?  Can you use non Apple gear to control it? 
The Kefs seem to be well engineered but I didn't see the price on that one either.  They both look like they cost something? 
The 'Mini Maggies'  are bigger but look like the business. How much real power do you think you need to drive them right?
Finally I have no idea why I was writing about damping materials and the like..
FYI:
I just replaced my Audioengine 5+ speakers (which in my opinion is very good) with the Audioengine HD6 speakers.
The HD6 as expected is an improvement in every way.
Bigger soundstage, improved bass, mids and highs with better timbre.
A wider expansion of dynamic.
I'm not sure what I'm going to do with the 5+ speakers?
