Some more stuff on cables worth bearing in mind if the sneaky cable propaganda ever manages to slip by your critical faculties.

It can happen to anyone. Subliminal programming works, and is all around us.

Some of this targeting is good, and some is not so good. We're all being constantly targetted into overload and then it's not always easy to sort out the truth from fiction.

First the infamous article from 2008 by Matt Buchanan.

Then a more recent update to see if the notorious Coat Hanger could be defeated by some modern audiophile cables.

And here’s Audioholics’ founder Gene DellaSala clearing away all those pesky psychological cobwebs for the rest of us in just under 9 minutes.


Are Perceived Audible Differences in Cable Performance Real or Psychological?

https://youtu.be/wrmNvQIl-D8

So what you're saying is, five months and nothing learned. Still stuck in the same rut. Is there even any desire to try and learn to listen?

Siegfried Linkwitz is one of the great contributors to audio science. His directions always made sense and it is very hard to argue with his basic premises. I think he may have been miss stated. A speaker has to have the same dispersion pattern at all frequencies. A criteria Magnepans and certain ESLs meet better than any other kind of speaker. I'm not entirely sure but I think it would be possible to design a horn system that way. This is probably the reason the K horn is so compelling in spite of it's phase and timing errors. Linkwitz's experimentation with dipole sub woofers was an attempt to create the dispersion pattern of his dipole speakers. 
Anyway, some great articles and Youtubes here. 
What we listen to are illusions, illusions of musicians playing real instruments and singing. Illusions are plastic and depend on the perception of the individual which is at once complicated by other motives and emotions but as has been demonstrated under the right conditions surprisingly uniform. I think most of our differences are based on opinions formed under the wrong conditions.

@mijostyn,

'What we listen to are illusions, illusions of musicians playing real instruments and singing.'


Good point. As time goes by we seem to be getting increasingly immersed in illusion trying to pass off as reality.

From the printed page to our smartphone screens, TV sets and workstations - it's all an illusion of a relationship becoming increasingly removed. Covid 19 has only made it worse.

Thankfully with audio we do have a fixed fundamental point of reference, the recording itself. All that any playback system can do is to attempt to play back the original recorded signal as faithfully as possible. 

The biggest challenge falls with microphones and loudspeakers and their attempts to capture and mimick naturally occurring sound radiation patterns.

We cannot, and should never blame playback systems for not being able to deliver what was never captured in the first place.

As for individual interpretation, well that's another issue altogether - one of biological capability and psychological interpretation. One that, although currently beyond our means to measure adequately, is not one needed to determine playback fidelity.

The job of the playback system is accurate playback.

What the listener then does with the signal after it leaves the loudspeaker is only an individual personal matter.


@millercarbon, 

We're not in the creation business are we?

We're only on the consumption end, and as such we look to the industry to provide the best products they can. 

What do you suggest we should be listening to and learning from? 

Isn't it better to leave that to the professionals who have both the time and resources to do a better job than we ever could?
