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.

His "theory" of skin effect at the frequency where he points it out is almost definitely wrong. W.R.T. inductance, changing, again, unlikely to be the effect of a simple cable. It is pretty much a given there are additional elements in this cable.

The impedance frequency plot as requested by djones51, will reveal the critical composite of this data ...

1. The lols are on you, since you discredit him, but were able to pick an obscure video by him. It seems you follow his video .. ahem!

2. He believe cables should be competent and does not believe there is any reason for them to be expensive, nor should they be tone controls. The piece you linked to proves his point not yours. He even has a section on the website for cable performance basics, none of which take much expense to accomplish.

It’s all over the place after 10KHz. This vid from a guy who don't believe in cable lols.

"The clocks aboard the airplanes were slightly faster than atomic clocks on the ground."
They were about 900 km/h faster.

Yes, I know. That’s another observation that shows Einstein was right. I’m not following are you saying Einstein can never be proven wrong? Newton’s laws work at small distances so he’s right but not at large distances so he’s also wrong. Might be Einstein turns out the same way I have no idea, I’m not smart enough to figure it all out.

>>>>I just got through saying Einstein didn’t believe in black holes but we know they exist. He also was wrong about quantum mechanics. That’s the way it goes sometimes.

A working theory of gravity. There are quite a few. In addition to the QM issue, scientists have had to make up the concept of dark matter to match relativity results to what they observe.  Why someone would feel the need to insist on something being right that they had no hand in developing, measuring or verifying, and for which their life would not change either way? Baffles me. Mr Pebbles?

djones512,445 posts07-08-2020 7:17amOur working theory of gravity is Einstein's theory of general relativity. It's held up pretty good so far. But we still haven't unified gravity with QM, either our working theory is right and we haven't figured it out or their could be another theory or a tweak of Einstein's theory. I believe the point is it isn't settled science.

Maybe the Roman Space telescope will answer some of these questions on dark matter and energy.
