... abit confused: how does a power cord affect the presentation of sound...

From a purely physical standpoint falling trees move air creating waves of sound whether anyone is around doesn’t matter. From a psychological view when those waves hit our ears and the brain processes the vibrations we turn and see where the tree fell. So the answer to the age old question is yes and no depends whether you’re talking about physics or human perception. When we test gravity our notions don’t enter the picture. If I believe I can flap my arms and fly I’ll still fall like everyone else who tries the experiment. It’s universal not relying on my subjective view of gravity but the objective reality of it’s force. Likewise with cables, they have measurable physical properties and they will vary not only from one type of conductor to another but within the same type of conductors. Are these differences perceptible? The only honest way to answer that question is to listen and see if we can tell and the only honest way to do that is when we have no preconceptions or biases. Since all humans are afflicted with these preconceptions and biases we control for them to get answers that are more like the gravity experiment where what I think doesn’t affect the outcome, we all fall.

Someone’s done more than their share of hallucinogenics!  So cute when people struggle with science but still think they have insight into a topic...just adorable.

The squirrels heard it fall.

" The deal, ie, how it affects, how it happens... is about the instantaneous delta of the inductive collapse of the field integration of the complex model of the power cord, under high delta draw from the DUT.This area of draw or complexity of the signal in the given ’moment’ is how we as humans, hear. "

Really?  The bear isn't buying it.

Do people still read textbooks?
