A challenge to the "measurement" camp

I’ve watched some of his video and I actually agree on some of what he said,
but he seems too confident on his insistence on measurement. For those
who expound on the merits of blind test and measurement, why not turn
the table upside down?

Why not do a blind test of measurement? That is I will supply all the measurement
you want, can you tell me which is a better product?

For example, if I have a set of cable, and a set of measurement for each
individual cable, can you tell me which is the best cable based on measurement
alone? I will supply all the measurement you want.
After all, that is what you’re after right? Objective result and not subjective
listening test.

Fast forward to 8:15 mark where he keeps ranting about listening test
without measurement.

By the way, is he getting paid by Belden?  Because he keeps talking about it
and how well it measures.  I've had some BlueJean cables and they can easily
bettered by some decent cables.

No measurements? ?

I counted 5 pages in the search where @geoffkait brought up gravity Andy2 so that is that 100-150 posts, and there are probably many many more, I just got bored. Not sure why he insists that gravity is the warping of space is anything but a theory when there are no doubt 100's of high quality science sites that quite clearly say it is a theory and many, oh Nasa for one, list 10's of other theories and what the current thought is on their potential validity. Dogma?  Ego not allowing to admit being wrong? First page on Google Search says so?

Inductance should be pretty flat. I don't think you know what you're talking about andy2, In a short run speaker cable it might vary by .17nH per ft. from 20hz to 20khz.

Look like you are talking about yourself.  But anyway, you just got a good education from me.  Now you understand your own flaw.  It's more complicated than you can handle and I taught you a good lesson.  

Tell us how will interpret the plots.  Otherwise, we will be laughing at your stupidity.

Air core inductor? ... going to be very flat out to fairly high frequencies. Stable plastic and air dielectric capacitor? Yup, that is going to be fairly flat as well out to higher frequencies. Of course, I have actually measured these things so I am not guessing, and I understand the properties of the materials enough to ballpark how they work.

Distributed impedance? .... we are no where near where transmission line effects are a concern, and given the small values of the cable to the speaker/amp, a single bulk value of RLC is sufficient, but it is not like you couldn’t divide it into 2, 4, or 8 and do a simple piece-wise calculation or determination that was well beyond audible detection.

You may be trying to make djones51 look like he doesn’t know his stuff, and maybe he doesn't, but this is a public forum, and there are people who do, and you are not in that camp.

Uh, I hope the inductance vs frequency is ruler flat

You realize that even the inductance vs. freq. of an actual inductor is not flat, don’t you? Now being a cable with distributive characteristic, I am not sure how it will be flat. Same for capacitance and resistance. They won’t be flat.

More to discover
