Diagonal seating?

OP here. Although my ears are sometimes turned sideways to the speakers, I am equidistant from each speaker on my side of the diagonal sofa. That helps, but doesn’t get everything the way it ought to be. Given the sofa and some peculiarities of the room, it’s probably unrealistic to think I can completely resolve this issue.

Thanks for your feedback, everybody. 

I have been down this road where I thought imaging shift was a result issues like the room, the electronics or my ears, but symmetric speaker placement along the center line of the room, mirrored toe-in and equal distance of the speakers to the listener (basically speaking) will fix it. 

I tend to not be so anal about seating and positioning, but then I use speakers that are somewhat forgiving as they are time and phase aligned.

So, if your 'distracted' listening moments sound good, I would leave well enough alone.

Maan I have to get stoned to find your solution indeed! It seems to me to rectify problem you might want to wear blindfold while listening and see if it really helps. I've seen some night clubs place speakers diagonally around the dancing floor which is kinda another hint for you to practice some dancing of the 70's era while spinning some tunes...
