Well, for some the knife is sharp when it shaves easily, for others it is just the beginning of true sharpness. If the knife can take this kind of edge, of course.
I have never experimented with one meter and two meter same model interconnects, but I am quite certain that there are people who can hear the difference with some or all brands and models. When I put one half inch Walker Audio resonance control disc on top of the tape deck, I clearly hear the improvement in clarity. Also, records treated with LAST record preservative sound slightly better, all of them. Are those two examples of mine significant? It depends, but the difference is small.
As for difference in hearing, I noticed many times on this forum that there are a lot of arguments coming from people who cannot hear well, whether they know it or not. I have met people with better hearing than mine, I had no reason not to believe them, most of them were musicians.
Oh yes, elevated speaker cables. Sometimes there is a slight difference that I can hear, sometimes not.
