It’s fine if someone chooses not to listen to something, because they “know” it can’t possibly make a difference in the sound, or for any other reason. In doing so, though, they give up the ability to make any credible observations about whether or not it makes an audible difference, or what the difference is.
Better Sounding Systems, Objectivists or Subjectivists?
When these two camps retire to their listening rooms, which school of thought tends to get better sound? Those who ultimately place their faith in measurements above actually listening to their systems? Or those of us who look at measurements, but ultimately make our decisions based on what subjectively sounds best to us?
