Cable elevators


My Saturday hifi tweaking involved digging out the family’s box of wooden building blocks and using them to elevate my speaker cables off the floor. Previously under an area carpet on a wood floor. Mc 601s to SF Amati with Wireworld speaker cables (to be replaced with Cardas). 
 

The result—mind you the system is playing really well right now thanks to my new Cardas interconnects—is greater clarity (I think), sound stage, and texture. This is definitely about wringing out the last ounce of the system and maybe I’m imagining the improvement. I don’t think I’d spend any money on buying risers, but what the hell why not use the old building block. Looks dopey and the family laughs at me, but dang does the system sound amazing.

Anyone else play with risers/elevators?

There is a measurable difference of lower capacitance when cable risers are used

@mc1969 -

I am on a concrete engineered slab, no carpet under my cables, engineered hardwood

     Makes sense, given that all of our cables exhibit the properties of an RLC circuit, the 'C' being capacitance.

     Capacitance changes, according to the dielectric, it's Dielectric Constant, and the amount of dielectric used.

     The Dielectric Constant of air = 1.    Wood can vary from just over 1 to 4, depending on grain direction and (greatly) on moisture content.

     I seriously doubt that engineered hardwood contains/retains any moisture, hence: no more change than lifting a cable into the air.

     Most carpeting consists of materials with horrible Constants.

     When your cable's lying on a material with a high Dielectric Constant; that's being added to that of the cable's insulation, changing the 'C' in the RLC, over whatever length.

                 WELL: the Cargo Cult's building another runway.

                                         Time for a rewind:

Cargo cult science is a pseudoscientific method of research that favors evidence that confirms an assumed hypothesis. In contrast with the scientific method, there is no vigorous effort to disprove or delimit the hypothesis.[1] The term cargo cult science was first used by physicist Richard Feynman during his 1974 commencement address at the California Institute of Technology.[1]

Cargo cults are religious practices that have appeared in many traditional tribal societies in the wake of interaction with technologically advanced cultures.

     Do a bit a research and you'll learn those primitives were limited in their understanding, of what they saw with their eyes, based on their prior experience, education and BIASES.

                                                A rewind:

                 It isn't that the Denyin'tologists are ignorant.

               It's they're knowing* so much, that's WRONG.

                       *heart of the Dunning-Kruger Effect

                                              OR, two:

     The Church of the Naysayer Doctrine (like every other faith-based, religious cult) has as many dopes as it does Popes.   

     Bring up anything resembling SCIENCE/PHYSICS, dated later than the 1800’s and they become apoplectic, not having the formal education to comprehend the concepts, or- possible ramifications.    THAT would be hilarious, were it not so pathetic!        

           Gimme That Old Time Religion, Gimme That Old Time Religion, etc.

        At the very first mention of something as simple as Wave Function (a BASIC tenet of Quantum Mechanics), the Cargo Cult will label you a KOOK.

        But remember: they can only view/understand you, based on their limited experience, education and BIASES.

         They have overlooked the fact that, if not for the hypotheses/theories and experimentation, regarding Quantum Mechanics: a plethora of modern conveniences, medical devices and the gear they so love, would not exist.

          Had scientists, chemists and inventors shared the doctrines of the Cargo Cult (Denyin'tologists), there would be no semiconductors, computer chips, LASERs, or Magnetic Resonance Imaging devices (MRIs).

                                         Solid State amps?

                                     OOPS (back to tubes)!

                                        Your Smart Phone?

                                        FA'GET ABOUT IT!

                                         Your car's GPS?

                                                NOPE!

    Then too: some may be willfully ignorant and just enjoy being contentious.

                        Others: obtuse, uneducated*, misinformed?

      *Typically, from what's been exhibited here: H.S. STEM, if that, would be a safe inference.

      Either way: the result, when the Cult begins it's rhetoric is a classic demo of the Dunning- Kruger Effect.

                                          But, I digress: 

       Bring up those pesky details, regarding the likes of QED, Dielectric Absorption, Poynting's theorem and possible application/effects, relative to frequency, that our musical signals are carried via photon or wave, outside the conductor and you're a KOOK?

         Again: the Cargo Cult can only understand anyone with an actual background, experience and education in Physics/QED, based on their beliefs, education, experience and biases

                                      Remember this?.

     One anecdote  that some may find interesting: their walks in the woods and how his father would encourage him to look beyond the fact that something in nature exists, but into why and how.

     It saddened him, that while attending college, during a visit home and one of their walks: his dad asked what he was learning in college.

     At that moment, he realized: if he tried to explain what he was learning, there was no way his dad could understand.                               

                            It wasn't an insult or condescension.

                                                Just reality.

                                    Oh well: let 'em go build a runway!

           Einstein got that last one wrong (Quantum Entanglement), BUT- I still wish he'd been alive, when the Hubble Telescope proved, what he considered his, "greatest blunder" (his inability to bring symmetry to his field equation, without lambda.

Another example of a hypothesis/theory, with no way to EXPERIMENT/MEASURE, what you're sure must be there, in some detectable way, or another.

                                            Happy listening!

             When a Deny'intologist can't savvy the science, they'll (typically) either:

                               pertinaciously persist in their puzzlement,

                              answer with asseveration from yet another,

                                                            or:

                                     dab at derailment with deflection.

                                                    No surprises!

                                    

 

 

                                          ^^^  YEP!  ^^^   

       The adherents of the Naysayer Church will never accept that there exists a multitude of variables, when an accurate simulacrum of performers and their performance in a particular venue, is the desire/goal.

        If their result differs from that of others, the aspects that they can't discern CERTAINLY MUST BE the product of the others' imagination.

        Of this they are certain: it CAN'T be THEIR system, room, or ears!

                                       Perish the thought!

                                      

                                   

- have you listened to cable risers?  Yes

- what was your impression?  waste of time and resources. 

             Tried and they did nothing!

                          Did I mention: VARIABLES?

What is the difference between carpet, porcelain tile or wood floor or wood blocks?

So how does raising a cable or cord matter?  I am not being a jerk, just trying to nderstand the science.

                 If that's true: read my last post/references, to this thread.

 The juice is what is inside the cable not outside the cable.

                 Not according to any science, after the 19th Century.
