My whole thing is "just try it". If it doesn't make a difference, then you are good!
And because one person doesn't hear any difference, doesn't mean another who says they do are a victim of marketing.
Quick story to illustrate my thoughts on hearing vs listening.
I've been working on a speaker for a bit. A project I've been mulling about for a few months. Experimenting with a coax driver and a capacitor less crossover. Was trying to decide between two values of the resistor (8.2 ohm and 10 ohm). The high end was different. One went higher, but was missing the bit just below, the other didn't go as high but held the info up to that point. There was a distinct difference to my ears.
I wanted an "unbiased" and "uninterested" opinion. I asked my 8yr old son to listen. Now, he has fresh ears and can hear a fly fart next door... He heard the clarity of the speakers, and commented on that. I asked him if he could describe what the differences were and if there was one he liked better as I A/B'd the speakers for him (Mono - L/R channels). He couldn't. I asked if he could hear a difference. He couldn't.
Hearing is biology. Much like sense of taste is biology. Listening is a skill, something learned or taught. Like taste, being able to isolate nuances is very much a skill.
Prior to Covid hitting, a friend was going through cancer treatment/surgery. He was unable to work for the better part of two years prior to Covid arriving. He was scheduled to have his final surgery but that was canceled due to the pandemic. He is a chef, and when Covid arrived, he got pretty down. I started fixing his stereo so he could listen to his vinyl collection. The transformation in his ability to listen for nuanced changes in a speaker build/tuning is astonishing. (I've built a lot of speakers for him). He is 64 and we often joke about the biological limits our age has put on our hearing. He is listening with far greater acuity than ever before.
I feel like this is a journey, and not a destination.
