A challenge to the "measurement" camp

While I agree with listening experiments with cables, my quarrel is with the "physics" used to sell cable designs. The most common is skin effect, which is accused of causing high frequency roll-off and distorting phase angles of different frequencies. Cable marketers flatter the buyer with their discussions of these things, secure in the knowledge very few people understand it with enough depth to be able to calculate what these things do. Skin effect increases the resistance of a typical speaker by about 0.o1 Ohms at 20 kHz, something that can be calculated from any E&M textbook used in master's degree level courses. In series with speakers with DC resistance of 4 Ohms the roll-off is less than 0.01 db at 20 kHz. Cable designers should know this and if they do, they can't be bothered to admit litz construction of individual strands "solves" a problem that does not exist. Accounts of phase distortion from different length signal paths in stranded cable and the signal "jumping" between strands might vary the signal path by at most a centimeter or two and at 3 x 10^8 meters per second, the speed of light, phase angle "smearing" is on the order of 10^-10 seconds. Nobody can hear such a thing. If the "distortion" between grain structure of copper emulating littler diodes starting and stopping signal transmission a long radio or television antenna could not overcome a diode threshold conducting voltage at the micro-Volts off an antenna. Resistance in a cable introduces Johnson-Niquest noise due to thermal effects of conduction electrons and it is proportional to the Kelvin temperature. This can be reduced by thicker cable but in a speaker sub-micro-Volts is irrelevant. Thus, I ask, why should I trust a cable manufacturer who charges hundreds to tens of thousands of dollars for a set of cables and why would not someone who invested his ego in buying such cables convince himself the thousands of dollars set of speaker wires makes a difference?
Everything else designed in electronics relies upon mathematics and real physics, but cables do not.
Can I be blamed for my skepticism after catching cable marketers for scientific fraud?

For sure not..... :)

Cables difference is a fact easy to experience.... But price there is thief and fraud also  too often....

The only people who make the claims you make Teo are people who don’t truly understand the technology. I have heard enough live and recorded music in short succession in a variety of situations to know, without any doubt, that well implemented high-res digital is the most accurate recording and playback, superior to analog tape at any speed. People who make claims about "missing resolution" in digital especially high resolution do not understand the technology. It is an ignorant position taken from a position of lack of knowledge and experience.

p.s. ever heard of FM or AM radio? ... been around way before digital.

when we get to the end of all that, we find that analog cables, in an all triode or v-fet system, is the only real functional signal capturing and playback chain.

No, that is just silly. You are confusing pleasing with accurate and they are not remotely the same thing. You are trying to take the complexity of sound, the ear and the brain, and claim the equivalent complexity in a signal in a cable or the storage of "data" required for that signal whether analog or digital. They are not remotely of the same level of complexity. It is a weak argument that is again, only made by people who have not thought this through.

The magic of the music has nothing to do with the format, it has to do with the industry. You seem to be joining mahgister on the conspiracy front.

Most conspiracies are stupidity and greed....


 And by the way i have not read Teo audio like a defense of vinyl versus digital....But like an industry greed  taking the easy way....

@drbarney1 , you should question most of the marketing w.r.t. cables. Most of it is made up with no evidence that what they claim is what is causing any audible difference. This is not a "measurements" thing. If what they claimed was true, they would show it with good old fashion listening tests, heck, they would at least "try" to quantify what they claim, but they don't. Why? ....
