I do not find that to be the case with my speakers. When I first heard them in David's room, my impression was of tone and dynamics, not so much imaging. In fact, the presentation of images projected forward into the space seemed markedly different from what I was used to from my Magicos at home.
Without asking David, I pulled them out into the room and aimed them straight ahead. (I had to move Tim's JBL M9500s out of the way). Here the imaging did improve slightly, but I do not think it was because they were pulled out of the corners. David's room is problematic and I shared how we tried to improve the sonics with some construction and reinforcement in the corners. What I did notice was the incredibly beautiful tone, the resolution, and the dynamics, though the bass energy was less.
Once installed in my room, the imaging was actually as good or better than with my Magicos, in terms of being more convincing and realistic. That has improved over time with leveling the speakers and fine tuning how they couple with the corners and walls of my room. Despite the fireplace, the imaging is actually very good, that is the presentation reveals a sense that the musicians are present in front of me.
I have not heard the Hartsfields and can not speak to their imaging. David's Bionors, and Tim's M9500, both horns, image extremely well based on my hearing them in David's big room with the Lamm and rest of his system. I suspect his power delivery matters too for this sense of presence and imaging.
