Speaker Placement - Frequent Placement Changes?

Set and forget. 

I only have myself to please and did many hours of placement and room treatment resulting in what I and guests think sounds perfect. At over 1400 pounds I’ll find something else to fret over, happy and done. 

Don't overlook your seating position. It can have an even bigger influence on the sound. Sitting at or near a null makes a huge difference. Near field is also an interesting experiment to try.

Agreed, I should add that I changed the chair recently and did find a better location. I am sure that given the height of the back on the chair this also made a difference.  An easy comfortable tweak

I should add it is important to start with speakers that are identically positioned in all three dimensions. They should be vertical without tilting to the side and they should be tilted back and toed in equivalently. I admit I only recently recognized the importance of this and it does make a difference.
