Why is science just a starting point and not an end point?


Measurements are useful to verify specifications and identify any underlying issues that might be a concern. Test tones are used to show how equipment performs below audible levels but how music performs at listening levels is the deciding criteria. In that regard science fails miserably.

Why is it so?

"The capacity of Humans for self-deception is apparently unlimited" - Mr.Spock the Vulcan."

     Is the unfathomable irony, of one that IMAGINES themselves a fictional intelligence operative, posting a quote from ANOTHER fictional character, lost on anyone?

                                       Then: there's, "prof" (snort of derision)!

He has also self deceived himself into believing that 15 systems worth of 40 year old stuff is the top of the mountain. He could have spent half of what he has invested into a good room and good components and actually HAVE a good system. It is pretty clear that he can't hear the difference. Self-deception indeed.

Look class!  This is the sound someone makes when they can't produce a reasoned rebuttal to an argument.

         Should anyone need a rationale for trying new cables or fuses in their system and is dissuaded by the Naysayer Church's antiquated electrical doctrines: take heart!

        Many new electrical facts have been established in the past 100 years, that support audible differences, between various cables, etc.

         I couldn't find anything like, "Updated Electrical Theory For Idiots", but- did manage to find something resembling a cartoon, that even a child (perhaps: even, the POOF) could follow.  It neither mentions AC in wires, nor does it go into the photon propagation of electromagnetic waves.   It does, however, emphasize/demonstrate how Electrical Theory has progressed, since the 1800s:

              (https://www.youtube.com/watch?v=KGJqykotjog)

        These next few presuppose a certain amount of knowledge, in the field of modern Electrical Theory.    Click, "more" in the first link's first answer, to get it's entirety.    Note how it mentions the OLD, "... commonly held misconception that the flow of electricity through a wire resembles a tube filled with ping pong balls...", to which the Naysayers fervently adhere.

                                            and:

        https://van.physics.illinois.edu/qa/listing.php?id=2348

        It's an established (measured) fact that an electromagnetic wave's propagation and speed, are dependent on the materials, of which the transmission line (cable) are made (ie: Dielectric Constant/permittivity).     The better (lower) the Dielectric Constant the better the flow and the longer it takes for that material, to become polarized.     One reason that anything that comprises an LC circuit (ie: capacitors, cables, PC boards), takes time to, "form", or, "break/burn-in".*      

          *Something that makes the Naysayers apoplectic.

          Even the most inane (regarding the sciences) must admit; braiding and twisting wires eliminates/reduces EMI interference.              
          That must lend credence to various cable geometries.

          That better dielectrics enhance the propagation of electromagnetic waves (ie: your music signal), lends the same credence to choosing cables with better materials (ie: Polypropylene, Teflon, air, etc).

           Of course: anything the Naysayer Church's popes can't fathom, they'll summarily dismiss.

                           PATHETIC twits, that they are!  🙄
