Hearing is believing?........power cables.......

Absolutely right Schubert. We have a handful of pointy heads that showed up here recently that believe they know it all and are out to save all of the audiophiles in the world from themselves. 

I can tell you are not a scientist

Schubert & cmsgolf-  This site could be the focus of a case study on hubris.

Let's see, what has, "Science" taught us?    At one time observation, which fosters common sense, led those interested, to believe that the Earth was the center of the universe.  After all, everything seemed to revolve around it.  Someone invented the telescope and people understood orbits.   Then someone watched an apple fall from a tree and decided objects with mass attract one another and Newton's understanding of gravity was the, "law" by which the universe was viewed.    Then Einstein showed us that the universe kinda like a fabric of space and time, that objects bend, and other objects follow those bends.   Proven, by showing that light is even bent, in traveling through that fabric.   The Physics of the universe demands mathematical symmetry and lately, things just aren't adding up.  ie: Observations would lead most to believe the shape of the universe to resemble a larger form of our own galaxy(a saucer), spiraling out from the center of what's called, "The Big Bang".    A certain amount of gravitation force would be required, to maintain that shape, which requires a certain amount of mass(remember that required symmetry?).   Guess what?  They've now calculated the mass of the known matter of this universe.   We're only 95% LIGHT of the figure needed for, "symmetry".    Not only that, but-  ever heard of the, "Laws of Thermodynamics"?   Now that scientists are better equipped to actually observe and measure what's happening in this space/time continuum, it seems the universe's expansion is SPEEDING UP(contrary to, "common sense").   BUT, BUT- nothing speeds up after an explosion's energy is expended, RIGHT?    SO- now we know that to have the gravity required to hold our known universe, in the shape we can observe and measure, we need to discover the 95% of matter, we don't know about.  HMMMM, must be something called, "Dark Matter" out there.   AND- what would cause the matter of the universe, to be speeding up in it's expansion?   Must be something out there called, "Dark Energy" that we know nothing about.   Then again-  there JUST MIGHT be other universes(The Multiverse) out there that are exerting gravitational and other unknown forces in this one.   But then, Quantum Physics is a whole 'nother ballpark.    SO-  the more we've ACTUALLY learned from Science, the more we know we don't know.    Bottom line, real, "scientists" understand that to actually understand this universe, one must often abandon, "common sense".    Someone once said something like, "The real voyage of discovery  consists not in seeking new landscapes, but in having new eyes."

Quite a dissertation.  Trying to figure out that really applies to power cords that cost more than a power amp.  Is it the science that makes them so expensive...or the marketing. 😆
