Those high end cables are a waste of money.
Probably true, but peer reviewed audio research does show that they sound consistently different. See https://sites.google.com/view/...
As explained in the research, quickly switching between sources doesn't allow people to properly hear the subtle differences in these high end systems. When extending blind listening sessions to at least 15 minutes, untrained participants could start hearing differences between cables with strong statistical confidence.
While it's not understood why this is the case, there are several theories. One is that it's difficult to forget the details of what you just heard when rapidly switching. Unlike vision, we can't just reinspect something we hear by looking again. The brain has something called echoic memory which stores 3 to 4 seconds of auditory information which could be causing issues when rapidly switching. There's also theories that a large part of the brain is designed to predict the future. Again this could obscure differences with two signal that are so similar. The brains predictive abilities would just fill in any missing details. Last, and somewhat contradictory to the others, is that when quickly comparing two sources you're forcing you brain to use working memory to hold differences. Long term testing lets you use more effective types of memory for making complex distinctions.
Basically it kind of means that these double blind tests that have been used for most audio tests is flawed. It's kind of like using an optical illusion to measure distance.
