I have no experience with either of those speakers but I've been considering buying the D1080MKII 08's (I have the M200MkIII's and I'm extremely happy with them, so I thought I'd go for another pair of Swans for a second computer). I've noticed that some compare the D1080MKII 08's to the A5's in terms of sound (rather than the A2's) despite the price difference. I can't say how comparable they actually are, but the D1080's and A5's can be considered full-size monitors/bookshelves while the A2's are small computer speakers. The Swans and A5's are about same size and have 5" woofers, while the A2's have 2.75" ones. Based on that, I'd personally cross the A2's off my list.
Unfortunately, I didn't save any comparisons, but I dug this up (see post 15): http://www.head-fi.org/forum/thread/395701/audioengine-a5-competition.
