Mr Soul .... Might be too late with my (1st ever) reply... but I went through this thought process and eventually went for the Aktimates. Believe the Aktimates are slightly larger but they definitely had more in terms of input/output options which influenced my decision. Most importantly: the sound. I am very very happy with the Aktimates and have had a few comments from others as to the quality of sound: good bass (plenty for a decent sized room) and crisp mid/treble - richer than Audioengine in my opnion. They took a little running in but I love them.
One additional point : I always planned to use the ipod dock in the top of speaker...but then found out it didnt fit when on my shelf (yes I know they should be on stands!!!). Anyway, I now have an ipod touch in a dock plugged into back of Aktimates (using decents cable). 2 points here 1) the sound is still great (and MUCH better than plugging the 3,5mm jack into headphone socket) and 2) I am now listening much more to radio apps (check out Radio Paradise - no commericials - and high quality) then my own music. Lesson learned: is you are not using the "ipod host" in the left speaker, use a dock!
Downside: remote a bit naff - I dont use it and would say that the volume goes up and down in (too) large amounts when listening to direct feed ipod. Very small beans.
Finally, I bought mine reconditioned at Audioaffair with hefty discount. All good so far!!
