@herman @gita Yes, I agree that "perfection" in placement is the objective but how to limit the effort required. The laser measuring device used by real estate appraisers is one method other than string or measuring tape. I have 190 lb. speakers and had to determine the correct distances from the front and side walls as well as the angles for each of the four corners of the speakers (tow angle). I think I got within 1/8".
I don't believe even most speaker manufacturers use precise set-up or build quality to WIlson's .0002" (whatever) specification.
I use two pairs of Shakti Hallographs to correct imaging for the room. It's not a budget tweak but solves the problem for my Legacy Focuses which are not the best focused speakers in my custom built listening room.
I agree that best and cheapest tweak if needed is the ear canal cleaning. It may not be considered a tweak but fundamental to sound/music reproduction.
