I went through the same thing as you when I got my new speakers. Before I had them, I always had the speakers aiming somewhere around the vicinity of my ears, give or take a few inches, but nothing more than that.
My new speakers seemed to have a larger lateral dispersion than what I’m used to so I experimented with them pointing straight out with no toe in and was surprised to hear a decent center image. Not the best I’ve heard, but decent.
Trying all manner of toe in, I settled on them aimed at where the palms of my hands would be if fully extended to the sides. Now I have a wonderfully wide center image that appears to adjust as I move to the side to show what’s beside/behind the performer as if viewing/listening from an angle, off center of an actual performance. Most uncanny.
I know a lot of it is psychoacoustics working it’s magic on me but a lot of it has to do with the high quality of the gear reproducing all those cues that make it possible.
All the best,
