@soix my speakers are about 30"inches from the front wall. I spent a fair bit of time talking to John Rutan at Audio Connection about speaker placement. Like I said, my soundstage is wide and focused with nearly no toe in but very little depth
Is that 30” from the front of the speakers or the back? My suggestion would be to try pulling the front of the speakers out at least 48” from the wall and see what happens. My guess is you’ll hear much better depth and an overall improvement, and then keep experimenting from there. The fronts of my speakers are about 6’ from the wall, just for reference. There’s nothing about your system I can see that should limit depth other than speaker placement, FWIW.
