Equipment in the middle effecting imaging? That’s really a visual issue to overcome.
It’s essentially ALL in your head, there are no sound waves in the middle.
Close your eyes, get the image of stuff in the middle out, there you have it.
Have a look at my last photo with the little christmas tree right in the middle. It’s not blocking any sound waves, it’s up to me to ignore what I see and go with what my brain puts together from any mix of l/r in/out of phase, timing tricks .... anything any engineer can come up with using zero center sound waves!
