The CABLE fallacy and Human Hearing.


Over many years, I have heard audiophiles online and in person talking about cables making an audible difference in their system. The ELECTRONICS sound different, not the CABLES.

Swap one out, swap another out, and there we go - a huge difference (improvement).

There should be NO IMPROVEMENT. You hear your systems capabilities with any decently designed interconnect, speaker cable etc. I am suggesting spending some decent money on interconnects, but not thousands of dollars.

First of all, 

We as audiophiles were not there when the original recording was recorded, mixed, and mastered. We have no clue about the true intent of the producer, the artist etc. 

All we can say is - "it sounds good" or it sounds "realistic" 

But these are interpretations not rooted in any observable understanding of psychoacoustics, or applied science or physics, or medical literature.

Certainly, 

Human hearing is incredibly sensitive and can pick up on many minute differences in sound due to the nature of the human hearing apparatus, and human hearing being sharply defined over millions of years of evolution. 

Human hearing originally evolved from fish gills 400 million years ago. Since then, it has evolved from our primate ancestors to the point where our ability to localize sound is excellent; because that way we didn’t eat eaten by a saber-tooth tiger.

Human ears evolved from the gills of ancient fish

it’s common sense guys. Not an opinion. It’s a fact.

If you dig deep, you find: 

Level JND: the tiniest change in loudness you can perceive (often ~1 dB under good conditions, sometimes less in midrange sensitivity).

Pitch JND: the smallest frequency difference you can hear (much finer in midrange than at extreme lows/highs).

Timing JND: tiny differences in delay or phase that affect spatial perception.

None of these IMPROVE with cables. The change you noticed already existed! 

What changed? You improvised and heard a specific subset of the music or a passage of it in real time, that you hadn’t paid as much attention to before....

In other words - it’s human observation divided by human confirmation bias plus faith. 

And then the CABLE BURN IN myth - 

Yeah okay, so you go to a tropical island with your family for vacation. Then upon return, your cables need to be burned in again?! 

No they do not. The cables were stable and in good condition when you received them, right? So then, what changed inside? Nothing changed. If someone needs to burn in cables for you, charge you a fee, and have it shipped to your house and that takes two weeks, then what? See where this is going? 

YOU CAN’T PROVE THAT CABLES NEED TO BURN IN TO SOUND THEIR BEST. IF THIS WAS TRUE, EVERYONE WHO EVER USED ELECTRONICS WOULD KNOW THIS AND IT WOULD BE WRITTEN IN ENGINEERING TEXTBOOKS.

IF you listen to your system every day, then notice it sounds "off" it is not because of the cables, unless they are defective, damaged, or have poor terminations. 

If you really want to compare sound quality, make sure the volume, the track, and the electronics are all dialed in properly and listen to the same track over and over. Make sure its a track you can listen to in a neutral way, not one that makes your heart pound or makes you feel heavy emotions. If not, then you have an unwavering cognitive overload, which will invariably lead to false conclusions.

Recordings such as electronic synths or simple instrumentals or musical instruments will be right to test with. See if you can determine if the sound character changes overtime, by pattern matching  specific sounds, or sounds in a specific sequence.

Keep a notebook handy and write down your observations. Then on day two, dial in the system exactly the same way and listen again. Write your impressions on a blank page. Compare the two pages. is the extent of what you're trying to communicate about the sound quality able to communicate the same message? Or not?! if not, there was never a difference to begin with if you are doing this vs. swapping cables.

Many audiophiles I know in person often play things at random and notice some nice things about mixing and mastering methods; but that is not the same thing as a real-life improvement in audio reproduction. So in other other words, if your listening session is sporadic and not controlled, you cannot deduce that the cables made a positive or negative improvement.

Yet, everyone seems to fall in to the rabbit hole.

Get with the program gentlemen.

I didn’t say they don’t make a difference.

Of course they can, but they shouldn’t. The signal from point A to B should be unhampered; and what you end up hearing are the electronics. They are producing the sound you hear. The cables are merely a bridge to connect them.

Bad interconnects such as those made for the lowest possible cost, and those with very thin, cheap copper have the following problems: 

1. Noise Pickup 

2. Poor Ground Connection

3. Excessive Capacitance

4. Poor Connector Quality

5. Intermittent Mechanical Connections

6. Ground Loop Susceptibility

7. Bad Terminations 

 

You are welcome to do applied scientific research on any of (or all) of the above qualifiers and tell me I’m wrong. But only tell me I’m wrong if  you have solid proof that I’m talking out of a hat.

I know this because in my career, many different types of wire, including but not  limited to internal wiring could be subject to all of the above if not properly designed and not properly constructed.

 Rigorous quality control standards were implemented over numerous world-wide facilities I managed. This is how you can get ppm (parts per million) and ppb (parts per billion) error rates, thus being extremely low and suitable for demanding clients who cannot tolerate failures in their respective fields; and who prioritize long-standing reliability.

You joined this forum at the end of May. 13 days ago? I’d normally say welcome to the forum. However, you’ve posted 160 times and started a few threads -all on the same issue. 

Perhaps it’s not your intent to be a troll, but it seems a bit psychotic otherwise to be so focused on what other audiophiles are doing. It also seems to me that you’re exhibiting a great deal of overconfidence as your understanding of both technology and science may not be as deep as you believe. And your social skills are not serving you particularly well either. 

Your claims to date can be distilled as follows:

You believe you have superior cognitive skills, knowledge and understanding than most of us here. Could be true. Might not be.

You believe all manufacturers of audiophile grade cables are intellectually dishonest.  Could be true. Might not be.

You seem to believe it is your duty to inform those of us attempting to improve our systems of the utter fallacy of our approach. You also seem to believe that repetition of will win you both friends and converts. 

Most people come here to learn and share. A few come to pontificate. You’re clearly in the latter group. It’s tiresome. It’s also unfortunately hard to ignore because you’re just so damn present. Can you throttle it back a bit?

@mgrif104 

So the Knight in Shining armor is here to take me down. 

My discussions are NOT all about the same issue. 

You call it overconfidence because you don’t understand what I write. It’s like trying to explain algebra to a fish.

I actually do have all of those things in full, because my corporate experience over 25+ years matters and counts for something. And my experience as a business owner (2 successful). All of this doesn’t just happen because of dumb luck or chance. I don’t believe in faith - I believe in hard work and dedication.

It is not my duty to inform any of you. However, my audiophile friends have been burned far too many times, and I want to try to help out in the best way I can. 

You said I was here to pontificate. I had once said the same thing about @cleeds , but we are on good terms now and I have nothing negative to say about him anymore. His last response to me was well-intentioned, well written, and honest.

My so-called pontifications are truly just knowledge in raw form. Because you disagree with me, that doesn't mean I'm factually incorrect. Do your homework and then return back with arguments if you hope to prove me wrong about a particular subject matter.

That’s all I’m asking for. Some intellectual honesty.

Some may find me intimidating. That’s okay. I was made for great things in life, many are not.
