In my opinion the Parsifals are perfect for your room. They work well relatively close to side walls (imprortant as your room is only 11' wide, unless you want to place them on the wide wall), and they don't need a lot of space behind them (especially if you set them up with the woofers firing forward). With the Wilsons and JM Labs, you might find the midbass overwhelming in your room. The Parsifals are wonderfully transparent (the mids have the "see through" quality reminding me of Quads), clean, dynamic and at the same time smooth and musical.
All of the speakers you mentioned are great designs. In a bigger space it would be a tough choice, for your room, I'd say go with the Parsifals.
