Why high-end cable manufacturers don't post measurements?

Yes, this is primed for cable naysayers.

Why?

Because there aren't any measurable differences between any reasonably designed cables.

Nor any sonic differences that can be readily identified blind.

Even the most expensive stuff from Cardas, Nordost, Kimber etc defy identification against the cheapest unbranded OFC copper design.

You can bet the above mentioned companies would publish their findings if they had any.

Alas there’s more chance of the British royal family publishing the results of Prince Harry’s DNA test.

this is a rhetorical question

If you want to use high priced ,I mean totally over priced cables ,its your choice.Nice to have money to burn.When you worked for a dollar an hour $40 a week 50 years ago.It make you question everything....Think about it there are people  here who would never buy a $40 cable ever ,ever,never....

Well,

I chose to believe in the concept of small diameter, individually insulated multi-strand, to minimize the 'Skin' effect of single or twisted strands of non-insulated small diameter strands. (Cat 5 like, what I use)

excerpt:

" Skin effect in audio cables is the tendency for high frequency signals to travel more on the surface than in the center of the conductor, as if the conductor were a hollow metal pipe.[3] This tendency, caused by self-inductance, makes the cable more resistant at higher frequencies, diminishing its ability to transmit high frequencies with as much power as low frequencies. As cable conductors increase in diameter they have less overall resistance but increased skin effect."

Idea, all frequencies travel/arrive in closer time relative to other frequencies, on a minuscule level.

I also believe the reason Analog bests Digital, is the minuscule difference of Analog's ability to get the overtone's timing perfect to the fundamental (despite analog being noiser, my R2R beating my LP, which beat CD)

Surely they have they the ability to measure it's existance, have they published the true measurable difference/advantage compared to ordinary twisted? 10' length? 20' length.
