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.

In the first place I never said USB cables create noise. RF noise can leach in through connectors. Are you ever going to offer any measurements?

It is always interesting to note that you can go to Wikipedia and read about skin effect and thus inductance issues.... but nowhere does anyone talk about what exactly these things are. just the math. just.. how it appears to work.

nothing about what it is, at all. The whole thing is circular and redundant.

None of that is of any use in discovery work. It’s more for self appointed policemen to use when they have decided that someone must be punished for breaking a ’law’. Exceedingly dogmatic and wholly useless for these discussions.

FYI, all of these discussions in audio about cables are the data points for discovery work. And Wikipedia becomes useless in that moment -Circular and living inside it’s own butt, tossing engineering level papal bulls around like they actually mean something. Jebus. 

The longer a question has been in existence, the more fundamental the error in the formulation of the question.

Actually you could be/might be/possibly be right about cable creating distortion. The trick is trying to explain it why? What is it in the cable that might create distortion? If cables does create distortion, then you said about cable is no more than just R/L/C circuit is wrong. So that is your contradiction.  Either you're right about distortion and wrong about R/L/C - you can't have both.

I was just testing you to see if you know but you so quickly changed your mind which to show that you do not know.

Measurements?

I’m assuming English is your second language so I’m being patient. Noise can leach in through poor connections, connectors, ground problems, wired wrong, the USB hub but the wires themselves just carry the noise. I am assuming you’re going to use good quality cables with sturdy connections. I also assume one cable will be cheap $15 the other expensive >$250. Supposedly you’re going to provide some measurements on these two cables. I’m not going to know which is the cheap cable and which the expensive. From these measurements I’m suppose to try and pick the expensive from the cheap. Is there something I’m missing?
