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.

If it's  simple then get 2 different  sets of cables and do it. It's all I really need but if you want more then get me the Inductance vs frequency,  AC resistance vs frequency, Capacitance vs frequency , Resistance vs guage or are you going to come up with more reasons  why I don't  need those? All you said was ask and you would provide. Pony up.

^^^Well we've made some progress.  Initially it's just the freq. plot, now you realize it's more than that so you're asking for Inductance, AC resistance and capacitance.  You also probably realize by now these are not flat either.

But I can make it simple for you.  Just educate us how you will interpret all the bumps and dips of inductance,cap, res plots.  How do you determine which is more importance when comparing diff. cables?

I'll make it simple for you. You're putting the cart before the horse. You said ask for measurements. I asked. Provide them and I'll explain why I picked the cable I will choose when I get them. It's becoming obvious for anyone reading this you have no intention of providing anything. Get the 20hz to 20khz sweep of two sets of cables of the same guage and connections. They can be different metals and insulation. 

You also probably realize by now these are not flat either.
Uh, I hope the inductance vs frequency is ruler flat. If not we can toss that cable first. 

Don't worry about what I do with the measurements that's my part, yours is simply providing them.

I don't think you even know what I'm asking for most of the measurements should be fairly flat except for the frequency sweep. For instance the AC Resistance vs Guage should be flat in the audible range and not rise until 50 or 60 khz.

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.

I guess unless you live in a paradise, none of these will be flat.  Again, if you can enlighten us with how you will interpret these variable and determine which is the better cable.
