I have Classic Audio T3.3s, very similar and have good results with them only a few inches from the wall behind them. I find it helps to have them toed in to the listening position.
I recently moved, in my old room I had the speakers close to the rear wall there as well and imaging was spectacular. At shows John Wolff and I have often set them up fairly close to the rear wall if the room was small. I think the best sound we ever got was at the Munich show three years ago; in that room Purist Audio had a program that did the speaker placement and despite very little in the way of room treatment, it worked quite well.
In a nutshell they don’t seem to be picky.
