In my experience, people who have good hearing do not hear differently but they might have different preferances and they might have different tolerance for distortion. For example, I don't have much tolerance for high frequencies distortion, some of mid and low are okay. I have a musician friend whoes hearing is better than mine but not different. He prefers the sound of panel speakers, I don't. But, he listens to mostly classical, and I don't listen to classical, only some neo-classical.
