I have said this ad nauseum: wire is not a tone control. It would be a wonderful world if changing a wire made an improvement in sound quality.
I DO find cables to be effective at seasoning the sound. They are not my first or even second go-to options, but they’re completely effective and legitimate.
The first option is speaker position, the second is room treatment, the third is any tubes in the system...later on, though, cables are another tool. For me.
