As is normal here you get a range of answers from zero to infinity, especially on this topic. My #1 rule is always “Follow your ears”, even to the extent of having regular hearing tests. I mean if your hearing is way off, it is not worth throwing money at. I hear differences between speaker wires an opt for “the low end of the hi end” and am generally quite satisfied. New old stock can be a tremendous value.
The older I get, the less it matters in terms hearing loss with age.
