Tweaking Your Speaker Placement

My speakers weigh around 130# and are on Gaia ones. In the past I’ve used butcher blocks and found they helped a bit, but when I went to granite, things just came together. With my current speakers, the tweeters are higher and don’t have the same dispersion, so I can’t use the granite anymore. 
Oh and furniture sliders are a must.  Whether under the granite or just under the Gaia’s.

Jim Smith explains exactly how to setup, measure and move the speakers in small increments in his book Get Better Sound

I am certainly no expert. Based on your follow up comments, I assume, you must be attempting to tweak the speaker’s position. In other words, you have found the sweet spot. You are hearing a difference in sound that you have never heard before and like what you’re hearing. If not, I would only use a 1/8 inch adjustment on the tilt not changing the distance from the wall, toe in etc in the beginning. Hope you are making progress.

Thanks. Rake angle is next.

I have also begun measuring my room with Room EQ Wizard and the initial readings seem to be reasonably decent, which was nice to see.

"Where did you find a head restraint that didn't feel like a 3D clamp in 4D space?"

I am glad it doesn't work that way. Luckily the tweaking is fine tuning the speakers within the room's acoustic space and isn't reliant on one's head position per se.
