Keep in mind that even with the best speakers, placement, and recording, the speakers will "disappear" only in a listening sweet spot likely not to envelop more than 1-3 listening positions.
I had a pair of Martin Logans for a while. They imaged very well when sitting with my head still, back straight, in one place on my couch. If I moved or stood up, it sounded like a bag was put over my head.
Since I could not strap myself in that position, I traded them for a pair of Dynaudio speakers that had a beautiful tone and could withstand severe volumes. Trade-offs!
