A Couple Little Things I'm Wondering About

In the matter of electromagnetic radiation from a speaker cable, at 20,000 Hz at the speed of light or close thereto, how could different arrival times of a signal through the fraction of a second of two or three meters of cable at 300,000,000 meters per second be heard? For one meter, far less difference more than a wool rug could make, that is 1/10 of a microsecond. Different arrival times at the speed of sound from a live acoustical instrument is magnitudes more. What fraction of the signal even gets through the insulation? How much dipole shifting in the dielectric of the insulator takes place and is it so slow the minuscule electric field of it able to induce in the cable itself more than a fraction of a micro-Volt? There are too many claims of questionable physics by cable marketers such as skin effect attenuation at audio frequencies which when calculated in a circuit containing a speaker with hundreds of times the impedance of a cable's resistance diminishes the signal current to the speaker by often less than 1/100 db at 20 Hz. What engineering credentials, such as graduate school, do cable designers have and where in any E&M textbook does the golden ratio appear? How can materials and labor cost anywhere near the $20,000 plus some speaker cables sell for? That is why I do not believe most of these stories about high price speaker cables and so many audio components. I am not suggesting some designs sound better to some than other. I just want some honest physics for a change.

You're not going to find honest physics on this forum to much hokey subjective nonsense. Cables resting on little cups or balls every so many feet has audible differences to laying on a carpet? If it wasn't so sad it would be hilarious. 

drbarney1,

You dialed wrong number. Please check your number and try your call again.

Stay away from cable and fuse threads. They will not be good for your health although they do get hilarious at times. You cannot make them up.

I have placed my speaker cables in the nearest inter-galactic black hole. As a consequence, I have zero interference and noise. 

I don’t hear a thing, as a matter of fact.

In this universe, "honest physics" is an oxymoron.
