Micro position adjustments

Does anyone notice some big sound changes from some small movements to the position of furniture or equipment/television positioned between your speakers?

For example, if I toe-in my tv or my preamp (that sits just between and below tweeter level of my ProAc Studio 200s) less than one degree, my center image becomes much larger, also comes forward.....and midbass to lower midrange is fuller. Bringing either or both back outward...again, even just a degree or less makes the soundstage more distant and images smaller.

Another  one.....pulling my equipment rack forward/back.....or moving my corner bass traps a mere 1/8” can change my system’s bass response and apparent overall timing.

This all to a degree similar to replacing a component.....

Now, my system is across the short wall of a 13’ x18’ room.....so this is probably affecting a lot of wall reflections etc....
