Sound reproduction is far more complicated than those little things. 😀
SY, I don't even closely see the relevance of that comparisons, which of them has anything to do with audio.

It depends on how many 2'nd order harmonics create your amp. Usually, when 2'nd order harmonics occur, their satellite is an infra-sound that corresponds to signal's envelope. While it is not audible directly, it is perceivable well.
For example, when the door sounds the same open it to one side or to another, it is perceivable.
Connect DC measuring tool to your speaker terminals and measure what you perceive.
Re: it is 'beyond' them
Yes Edmond, the phase of the speakers were reversed but by changing phase in the digital domain afterwards did not make an easilly noticeable difference. That's the reason why I believe that absolute phase is not that important but somehow changing polarity with the cables, there is a difference.

Re: Re: it is 'beyond' them
If you change polarity before rectification occurs, you hear nothing. But when change after, you perceive it.

Wavebourn, although I don't understand a word what you say 😀, it is quite interesting. IIRC there are about 20mV dc on the OP, could that make such a difference?

Andre Visser said:
That would be the only thing I could think about that could make a difference.
To hear the difference in cable direction you need to turn the cable around and keep the same polarity.
Andre Visser said:
No. I don't mean constant DC shift. I mean "variable" DC that follows your musical signal. SE amps are more "directional" than PP ones.
When the person breathes an air goes in and out. When the singer sings an air goes out, in pauses the singer breathes in. You may not hear that, but you perceive well. You perceive a kick drum. You perceive a horn. You perceive organ's air flow from pipes. Recorded digitally such sounds loose their infra-sound parts, so you can swap polarities forever, but hear no differences. But when an amp distorts asymmetrically it "re-creates" that "breeze" of a natural sound. It is perceivable. So, when a trumpet play, but you perceive the musician inhale, it does not sound natural.

I’m not talking about the polarity of the cable, that’s the whole point.
I’m talking about the amp and speaker.
stinius said:
Amp - speaker polarity reversion is pretty audible. But I am very curious to know more about 'cable polarity', as it has been mentioned here 😉
PMA said:
Agree, the amp/speaker polarity reversion is what Andre heard, not the "cable polarity"
stinius said:
Some people say they hear cable polarity. Similarly, some say they hear voices from electrical outlets that say them what clothes to wear today. However, more usual place to hear such voices are especially organized for worshiping purposes. But audio setups sometimes are organized such a way, and used similarly. People spend so big money they can't not pray on what they got...
Wavebourn said:
I use a Class A, PP amp and did not notice any DC shift on the scope when running tests but I will make sure.
I don't have a problem with breathing 🙂, that sound very natural on my system.
Thanks

I don't mean whisper, I mean low-low-low frequency sound pressure. In and out, in and out... Light breeze of wind on your forehead, on your face, moving your hair a little bit... It is subtle, but you perceive it when sit down comfortable, relax your back, your arms, your legs, your chest, breeze deeply and slowly, feel free and happy, and with each and every breeze feel how your face relaxes and you go in deeper and deeper trance... Right... You are relaxed, you enjoy the music, you see how singers and musicians inhale... exhale... And the whole your body feels that...
Isn't it wonderful? 🙂
As I implied, non-believers in others experience make this thread difficult to for audio designers to get anything done.
You need to listen elsewhere. Firmly established in the literature decades ago.
Wire directionality (in the sense of a single conductor) is something different, a claim with no solid subjective or objective evidence that would require all the aforementioned technologies not to work. If pointing this out gets in the way of the tale-spinning, my apologies. I'll go back to eating my popcorn.

Honestly, I can make you hear that. But I don't use power of hypnotic suggestions for such unfair purposes. Suggestions to open your mind to your senses is a totally different thing, at least it is fair, so I can respect myself. 😀
