No, no. No critiquing here as I think you have a world class set up with regard to room, eqpt and attention to detail. I was looking for your thoughts, experience and opinions.
I am of the belief that our brains have difficulty with "seeing" performers with the wall close to the speaker - that our eye- brain has difficulty "suspending the disbelief" that palpable full sized figures are "there in the room". I have found that the more space behind my speakers gives me more stereo ("solidness"). As an experiment, I once placed a set of stacked Quads in a hallway between 2 open rooms with a total front wall to back wall of about 50 feet. The speakers were about mid point and the image seemed to go on for ever from the speakers to the back wall, about 25 feet. It was spooky. Others could "hear it" also.
When folks dim the lights or close their eyes, the speaker-wall distance may become a non issue ("out of sight out of mind"?). At least that's what I think.
Just looking for other's opinions.
