Looking for wider soundstage

The pictures help. I'll just throw out what I see and you can just consider what I am suggesting. What I would do is pull the speakers out into the room a foot or two more and add some toe-in. The tall equipment rack is not helping and the sofa is killing some needed reflections. I know it's a living space but acoustics don't care about that. Happy tuning.

It's going to be a setup issue you got the gear. Waiting on pictures.

One way to make changes is to strip out the room, put your gear on the floor and find the speaker placement that works the best. Then start stacking your system and see if it has an impact, then start putting furniture where it needs to go and asses that impact. Soon you'll have a handle on what all the effects are and what you can live with. It's a good thing to do when your SO is on a trip out of town, lol.
