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.

I don't think you know what you're talking about
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.

Not sure why he insists that gravity is the warping of space is anything but a theory

If you're not sure you must not be a very good reader because he already said why. When a guy with 23k irrelevant posts bothers to actually answer straight up you should give credit where credits due.

This "anything but a theory" actually solved a problem in astronomy, where the orbit of Mercury was known to be off by some infinitesimally tiny amount. This "anything but a theory" came along and showed that Mercury was close enough to the Sun for its gravitational effect on space and time to perfectly account for the discrepancy in the orbit of the planet. I was going to insert a link here but its way past time you started doing your own work and not just scamming off of those who actually know stuff. (Was thinking of another word but stuff is more your reading level.) 

Gravitational lenses offer another demonstration of this "anything but a theory". Galaxies are very massive, and so this "anything but a theory" predicts they curve space and time around them. If this really is the case then the light from other much more distant galaxies will be bent around them. Sure enough, there are many such examples of distant galaxies that appear in the wrong location, or sometimes even appear as double images, because of the way the light from them is bent as it travels near the galaxy in between. 

This one I will provide a link, since its a funny smiley face, much like the one on my face right now, as I contemplate just how utterly, thoroughly outclassed you are here. And always. And not just by me. https://www.thoughtco.com/introduction-to-gravitational-lensing-4153504
Move along. Please.
I think you put yourself in a bind. (To the djones or robert or atavid ...)

Here  these two positions you have to take:

1. Plots are flat.
If the plots are flat, then by definition you can’t tell the difference among the cables because they are all flat. Then your conclusion has to be all cables sound the same because they all measure the same - FLAT.
But of course cables don’t sound the same so this a flaw position.

2. Plots are not flat:
Then you why don’t you enlighten us how you would interpret these plots - with all the dips and bumps at different frequencies. Here is the second FLAW because nobody knows how, and certainly you don’t know either.

That’s the point but some people are too thick in the head to understand.
3. You don’t understand what these plots illustrate nor the concept of bulk LRC.

Personally I have not put myself into a bind since I have no made any challenges, and have only voiced basic support for the concept in the video that using cables for "tone controls" is rather silly ... $1000’s to replace pennies of components, maybe a few dollars in low volume ... makes total sense to me.
