There are a lot of possible answers.
Firstly: Sometimes there is a difference. This is honestly not disputable. Cables can be designed to color sound, so can amps. Amps driven to clipping clearly sound different. Amps which cannot generate sufficient current are going to sound different. etc.
Outside of that, there are two possibilities. One is that some people don't hear obvious differences; the other is that people hear differences that don't exist.
Actually there is a third possibility: that being that people make changes they don't realize they made. They switch amps but don't level match. Now everything is louder (which sounds different to the ear, not just louder)... for example.
Why would people not hear things that are obviously there.
They could have broken ears/brains; though I've seen no studies supporting it, nor do I see correlation with people likely to experience hearing loss, nor do the same people fail to hear differences in speakers.
They could be imagining no change. I'm not aware of any study on that either.
Why would people hear things that are not there?
That's widely studied. Tell people the wine they are tasting is more expensive and it gets better reviews. Tell them it's cheap and it gets worse ones.
There's an experiment where music was played twice through the same rig, but the second time large impressive speaker cables were shown to the listeners. They liked the second performance more.
We hear differences where we expect them. Dye a grilled cheese green with food coloring and ask your kids if it tastes the same.
