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....

IMO speaker placement (including distance from the walls, toe in, and rake angle), as well as furnishings, may tend to have a more significant impact than the choice between two good amps or between two good DACs. I'm amazed at some of  the photos I see of very expensive gear with the loudspeakers crammed up against the walls and corners (along with minimal furnishings or room treatments).

We have a pine cabinet in the left corner of the front wall.  Test tones seem to demonstrate its impact on imaging.  An up-moving right-speaker test tone will seem to go straight up from about eye level toward the ceiling behind the right speaker. However, an up-moving left-speaker test tone will seem to go straight up from about eye level, then abruptly shift to the left after it reaches the top of the corner cabinet.
