Question for cable/wire naysayers.....

For those who state that cables don't make a difference...... are you saying that all cables sound the same?  If not, what are you saying?   I've experimented with many different brands and materials and I can't possibly believe that those naysayers hear no differences.   And if the science says that the cables should sound the same, a simple experiment (listening!!!) should prove otherwise.  Or, are these naysayers not listening for changes in resolution, soundstaging/imaging, coherence.....and so on between cables?  Please elaborate on what you are NOT hearing and feel free to drop names.  What cables have you compared that didn't sound different?   I've just gotta know.  I'm floored every time I see a post or response in which cables are called snake oil or something comparable.  Please enlighten me......Thanks.
