After reading your thread, I decided to check out a review of the Magico A5. Have you read the Absolute Sound review of the A5?" If you click on the picture you’ll see it.
Here’s a quote from that review: "Its sealed enclosure makes it well suited to near-wall placement. The under-11″ width and under-45″ height make it small enough to sit in most living rooms without calling much attention to itself, until it starts to play."
The author also positively references Magico’s VP Peter Mackay coming over to his house to help place Magico A5’s for him for his review. I couldn’t think of Peter’s name when I wrote my above post, but he’s the one I spoke to and got the advice from on how close you could place A3’s to a wall. You should give him a call at Magico. I spoke to and exchanged emails with him a few times and he was quite helpful.
