there are really 2 questions.
1---looking at your picture, would it be better to move the rack to the side?
2---in a perfect situation, is it better to have the rack between the speakers or on the side.
answer 1---in your case it’s better to keep the rack there as it provides some break-up of reflections from the flat back wall. maybe if your room is big enough to get your speakers farther from the wall behind and you could add some diffusion on that wall, now maybe getting the rack out of the way would be a net gain.
answer 2---yes; when chasing perfection a rack between your speakers at some point becomes a liability. and while on the side is not perfect, the net gain is for the side location.
look at pictures of my system here for where it’s better on the side; my room is purpose built and finely tuned. much of which could not be done with gear between the speakers.
