Looking for wider soundstage

Thanks for those recent suggestions. I will try them. 

In my opinion,from my experience, if you’re going to have a rack in the center, pull the speakers well out in front of the rack.  I have a much smaller room,with rack in the center.  I have achieved a wonderful soundstage. Can it be better?  I think there is always room for improvement.   
  If your wife has an issue with leaving the speakers out,move them back when not doing any critical listening.  Enjoy the journey. 

@ backdoor-

I know it may seem counter intuitive but have you considered rotating the "audio" components of your system to the shorter wall where the display is currently located? (Assuming that I'm understanding the dimensions you provided). 

designsfx I have thought about that. The logistics of the room as it’s setup for tv viewing would make that move difficult. I would really like to try that though. I could switch sides with the listening spot and the electronic/speakers. That would put a curtain behind the rack and speakers. Would that be better than current setup?

I believe it would help as it will change the relationship between your speakers and the room boundaries. It's easy enough to test without moving everything by temping in longer speaker wire and just moving the speakers. If it seems to improve then you can plan a more detailed placement. If you'd like to try it I can pm you starting placement dimensions.
