You're almost making sense. But without a 'difference' there can be no 'better'.

It boils down to people claiming as fact what can only be opinion.

That flawed beast science knows quite a lot about cables and signal transmission, telephones under the Atlantic, the wire from your satellite dish, 1000M Ethernet, making ADSL work, the list is endless. And all those are much more difficult than a metre of baseband audio. But science appears unable to offer any explanation for cables sounding different when they have nominally equivalent electrical parameters. So it's over to the golden ears to substantiate their claims.

Or do you have no curiousity at all?

Of course if spending £400 on speaker cables makes you feel good about your music then that's money well spent. But it doesn't say anything about whether the cables have an effect on the sound.
