Two surprising things I found that improved my imaging and staging...

Agree with follow your ears through the journey. In my experience, having nearfield or having a television involves being closer to the speakers. I notice that most deep bass then is harder to create since long waveforms need room. Some things are lost in this configuration you just may not know are missing. Also placement and toe in are great ways to listen and understand how the speaker interacts. For years I have had my Maggie’s with the tweeters inside. For fun I swapped them to the outside and to me it’s radically more listenable. Positioning speakers in your room is far preferable to swapping out equipment or cords to learn what sounds good to you. 

According to Cardas my 16 ft wide room should have the speakers 7 ft to rear wall, HUH ?

Correct me if I’m wrong but isn’t the goal to get a solid center soundstage, great sound,and the speakers disappear? Towing in too much gives away the location of the speaker. Again I’m referring to my Monitor Audio broad desperation speakers. 

Since I moved from a 1200 sq ft listening space in NYC to a 550 sq ft listening space in The Hudson River Valley, my speakers give me the greatest natural balance, detail and spaciousness when pointed straight out, not toed in, and when making the space between each and the side walls equal to or slightly greater than the space between the speakers themselves. 

Two surprising things I found that improved my imaging and staging.

Best for sound stage imagine and depth is to have nothing between the speakers (even the wall) just have a small wall section behind the speakers for bass loading.  https://ibb.co/1MDg242
