Which power cords have high resolutions and separation??

@ebm 

Are you advocating jumping on cables as a new tweak?🤫

I will challenge anyone.  Blindfolded on video. I will swap out the cheapest power cord for the most expensive so called high end power cord and I guarantee you will not hear a difference.  Impossible.  And don't get me started on all the other nonsense that I read out here.

Where do you live? I’m sure a local will take you up on that. I would, if you lived near me.

There was one blinded "test" done on another forum which supported your hypothesis.

Religious fervour. Might this actually depend on the resolution of the system used? Or do you simply know better?

He probably can’t hear any difference through his Bose speakers.
