Do your ears deceive you?

"Maybe you could define of what a sufficient system is made."

One where you can hear the differences between cables.

Cables need to be considered as a component not an accessory. As with any other component system synergy is the key that unlocks the door. IMO the issue with HEA(retailers/reviewers/YouTube) is the focus on 1 component NOT the complete system.

"If you can’t hear it you either have the wrong cables, an insufficient system, an inability to hear those differences or confirmation bias against cables." 

Or Door #4, there are no audible differences to be heard.

Claiming  'insufficient system"  is the height of arrogance close only to  blaming "an inability to hear those differences."

Maybe you could define of what a sufficient system is made.

It was not my intention to appear arrogant in regards to the 'insufficient system' remark. This just comes from experience as I have built my system. I believe that the more refined your system becomes, the higher likelihood that cables will make an audible difference. Where that level of refinement starts is dependent on too many factors to objectively define it.

Secondly, I think it is a simple fact that not everyone can hear the difference. I believe if you invited a group of non-audiophiles to your home for a cable shootout, many of them would not perceive the difference between cables, though some percentage might. 

I have had a couple of cable changes that resulted in such a dramatic contrast that I think just about anyone could hear the difference. More often I think the changes are more subtle and more obvious to the owner of the system.

In other news, blind people are convinced everyone else is just making stuff up and there's surely no such thing as sight.

I believe if you invited a group of non-audiophiles to your home for a cable shootout, many of them would not perceive the difference between cables, though some percentage might. 

Similarly I believe if you invited a group of audiophiles for a cable shootout where they knew which cables they were listening to you'd get completely different results from hearing the same cables if it was a blind comparison.
