That´s about the master.
And of course nobody knows how a recording is going to sound exactly at YOUR house, let alone how YOU are going to perceive it.
But, they have a pretty good idea of how the recording is going to sound to a lot of people.
And that´s also a bit the point. The topic started with speaker cables.
Speaker cables are like the 2nd to last step (the last being the speakers emitting sound) in a long, very long, chain that results in a recoding.
Many technical and artistic decisions are made throughout the whole process.
How much difference do you think a 1-3 meters of cable are going to make given the whole chain behind?
Asking is already admitting there are differences in speaker cables 😉 , which I think, are none if you use technically adequate cables.
