That's happened on my system--something I noticed even back in the 80's with much different gear. I believe the main culprit is sound reflected from the side walls and perhaps the ceiling and floor. It can be remedied to some extent--perhaps a large extent--by adjusting toe-in and tweeter angle. (I think it's 90% a tweeter issue.) Also, if your room can tolerate it, a lot of acoustic treatment can probably make a big difference.

But even when I've got everything just right and have very nice imaging from my listening chair, there seems to be a sweet spot fairly near the speakers and above them (i.e., that I get from a standing position) where the imaging is particularly fine. (The spot that I vividly remember with my Dahlquists in the 80's was only about a foot away.)
