Speaker Placement - Frequent Placement Changes?

I will explore placement issues if there are any changes made to my system or the room...otherwise not much except if I'm in the mood to for fun...minor moving tweaks are easy with my speakers...

Still tweaking placement for 7 month-old speakers. I am amazed how a few degrees toe in or out or a few inches toward or away from the front and side walls can affect the sound, mostly in terms of imaging and spatial cues. Currently happy but I will probably experiment again. Tape on the floor is your friend.

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.
