One of my favorite web pages:

Also a guy was interviewed where I work and was asked if he thought A/B tests were a good idea (which are you take two different signals A and B and switch between them not knowing which is which). He said no which was a bit of a surprise and when asked why he said “because it makes audiophiles look like idiots”. Its true with things like these cables. Nobody can hear the difference.
