Do RCA cables have a sound? ChatGPT says they do.

[mhardy6647]

speaking of AI -- I am (so far) actively avoiding any encounters of the LLM AI kind, so I don't know... but...
How do the AI chatbots do when asked about some of those classic internet "Fools! They laughed at me at University, but I'll show them!" topics , e.g.,

• chemtrails
• scalar energy
• thimerosal and autism (or whatever)
• [mRNA] vaccines and whatever

You know, all that stuff they don't want you to know about.

What relevanace does E ink have? It is just another technology of digital display.

It is not mechanical but still can be "correct" twice a day.

Just a reminder: artificial intelligence originates, ultimately, in human beings. And human beings are idiots.

Yeah - but it wasn't the "correct twice a day" that made the clock under discussion "mechanical".

It was the "being mechanical" that did that.

AIs spread misinformation. Beware AIs.

AI's that do that are said to "hallucinate".

It was the "being mechanical" that did that.

I thought the premise was that being correct twice a day was not an analog vs digital distinction but a mechanical vs non-mechanical. Any clock that displays digits of precise finite value to represent time rather than an imprecise and possible infinite segmentation of space to represent time can be called digital.

If you want to get really scared about LLMs, read this: https://arstechnica.com/science/202...less-the-risks-of-ai-for-scientific-research/

Apparently some otherwise respectable researchers raised the idea of using LLMs instead of humans in psychological research. Which in our world would be a bit like expecting the cardboard box a speaker came in to sound like the speaker itself. Just unfathomably stupid. And they have PhDs.

Imagine how stupid things are going to get with less-educated folk.

Degrees don't make you smart, some of the dumbest people I've ever meet had PhDs.

I certainly agree, but you'd think someone specifically trained to do psychological research would understand you need actual people to generate data about people. You'd really hope so, anyway.

Not really, some academics are incredibly weird, illogical, etc.

In college i worked part time as a paid research assistant. One day during a departmental meeting a professor told a few of us he bought a bigger monitor because "he needed more storage space". My peers and I were looking at each other like wtf? A few days later a friend found out exactly what he was talking about. He stored everything on his desktop (several hundred individual files and a handful of folders).

Oddly… in a blind abx test we were able to pick out a certain rca vs three others 100% of the time,

Not all RCA interconnect cables are good interconnect cables!
In fact some audiophile/boutique cables are just terrible!
The audible differences will come down to susceptibility to noise or interference.

I simply had a rant about mechanical clocks being referred to as analogue clocks. They are not. My comment was nothing about digital displays or about right twice a day. Feel free to go back and read the post you quoted.

GIGO. You'd get better answers from a toddler.

Of course, they can. Especially those that are poorly made and have higher resistance or capacitance. Most competently engineered cables will be transparent.

I made three of the four cables, from cable ranging from 1.50 to 6.50 a metre, the same plugs and silver solder used for each lead

I am happy that all cables I made were good, not poorly engineered as you seem to imply should make a difference

I think he is referring to the actual cable used, not you ability to properly construct them.

The capacitance and resistance did vary in the three, however we are also told that within reason it should be inaudible, yet we were able to identify one cable with 100% accuracy

So if it audibly alters the sound, it must be possible to measure the resistance, capacitance and inductance.

Then do the calculation of the effect on frequency response (taking into account the input and output impedance of the devices on each end of the cable) and see why.

Or just do a frequency response measurement with that cable compared to the others if that is easier.

One moment, please...

just to keep this topic going

The measurements confirm what everyone already knows.... RCA cables measure different.
RCA cables have different shielding.

But lets be real about for instance the cable 'impedance' test.
We see measurements in the range of mohm to several ohm.
Let's do some calcultions based on a 1kohm load (which is already unrealistically low).
With 0 ohm there is no attenuation.
With 5 ohm there is an HF attenuation of a whopping 0.02dB (at 200kHz) !
That's going to be audible for sure.

The 'audio test' also already confirms what everyone knows... no correlation between measurements and subjective evaluations.

for the conclusions they drew:

Let’s conclude the article by saying that every cable just works. We didn’t hear a really bad cable. Even the stock interlink still did certain things just fine

That seems correct.

The correlations observed suggest intricate relationships between the physical and electrical properties of the cables and their performance in signal transmission and handling.

Not surprising to see a correlation between cable construction and electrical properties and thus signal transmission.

speaker cables are not RCA interlinks.
