Please understand that many (most?) audiophiles use there ears as a guide to what sounds best in there system(s). They do that regardless of measurements telling them there shouldn’t be a difference. That is the crux of it, & it ends up as a circular argument as those that cannot tell the difference tell those that do it’s simply bias, placebo, waste of money, wishful thinking, whatever.It is not an argument....
I can tell you wholeheartedly that cables & tweaks make my system shine. Does it sound good without them? Yes... but it sounds a lot better with them in place.
It is better, it is a complete case....
:)
i could tell the same tale for sure for the judge.....
Except i will add for example that there could or would not be a difference if someone add a piece of shungite on top of the amplifier transformer ( that will compress the sound and degrade it at this spot) or if someone add a piece of regular quartz at the same spot(that will increase too much mainly the high frequencies degrading also the sound in some opposite way); but there will be a big audible difference between these 2 .... I learned to play with these differences to reach the potential of my audio system with many other experiments in another different road also....
In relation with the kind of speakers you have, moving the chair will not change the sound in the same way, or on the same scale, that changing "some" cable or making the little experiment i just suggest...Distorting the imaging for example is very different than compressing the sound even if these may be linked....
I will add that my little experiment is more than most argument, because reproducible....Measurable? in theory yes....In practice probably,but i am in no way an engineer....And i cannot wait for them to transform my own audio system at peanuts costs for the better.... Homemade experiments are the road....Listening with the ears and the body is the way....

P.S. i will repeat here that, like roberttdid advise, it is not a good idea for a beginner to invest big money on cables, there is much false marketing ploys here, and i will add that there is way more spectacular way to imporove the system mostly linked to the 3 embeddings of any audio system...Upgrading for a better design in an electronic component will give also better improvement than just changing a cable.... But for someone with a top of the world system already, rightly embed, some cable can make big differences, for most people ,s system not so much....
