Cable Directionality - do you want proof

[Thompsonuxb]

Actually major post a pic of a variable DC wave graph operating above 0.....

 

[Thompsonuxb]

...Your speaker will alternate between being in phase and out of phase. It'll push and pull.

It would be like constantly switching the speakers polarity...

It does constantly push and pull, but it's doing it tens of thousands of times per second. This is why if you wire the speakers out of phase one speaker pushes while the other speaker pulls and they cancel-out each other, typically at the lower frequencies first because low frequencies have the longest wavelengths and cancel each other out more easily (plus usually they're mono).

Think of a sine wave. A pure sine wave has equal presence above and below zero:?

The upper half represents +ve voltage and the lower half represents -ve voltage. The amplifier sends this out to your speakers, which typically have a coil wound around the pole of a fixed magnet. The electricity from your amp causes the coil to push out or pull back depending on the polarity of the voltage it sees, depending on whether it is attracted to or repelled by the megnet. The coil is fastened to the cone, which in turn does the same thing and creates sound. You get it? Hollar if I can help more!

The coil does not 'pull back' - it 'trys' to come back to rest the variable current keeps it 'extended'.

Think of it in terms of music.

Shirly Bassey singing 'Goldfinger' for example.

When she belts out 'Goldfiiiinnnnngaaaaaarrrrrrha!' the increase in current holds the coil 'out' as she tails off you get less current you hear the decay as the coil oscillate less to come to rest. The speaker cone oscillates to reproduce her input into the Mic.

Now you apply your AC principles of the coil pushing and pulling.

You guys mistake a variable (modulated) DC for AC.

We will come back to this again and as is always the case you guys will see your mistake.

That animated example of a speaker is pretty good actually.

But take a look at your speakers in action and think about it.....

He is hard selling the niagra I have said that numerous times

There is not 1 mention of any audioquest cables in the whole video that is what I have said also

The video stays constant through the demos - there is no trickery you can tell as the volumes are identical.

The sound changes because the sound changes and it's not a small difference in the second test

Sorry if the times are wrong I did it that to help clarify the various demos in the video. They can't be that far off.

How grumpy to complain about that

Actually there is. Even in my short (too long) watch he mentioned them.

 

[steve_1979]

But look at it this way guys. If somewhere among these ten pages of **** we've managed to teach Thompsonuxb how speakers work, something good has come of it [/unusually positive]

Judging from post 159 I think you may have spoken too soon.

 

[steve_1979]

Can you then confirm for me what tripod was used to mount the camera and what external or built in microphone is being used to record the audio?

Can you confirm that the camera was not moved by even 1mm in either X,Y or Z direction and the orientation angle was not changed by even 1 degree at any time?

Can you confirm what codec and bit-rate was being used when the camera was saving the audio to memory and if it was saved as a variable or constant bit rate file?

No of course you can't because it's just an amature YouTube video of unknown origin.

...and the camera/mic used is just one of the many variables that I mentioned.

Sorry must have missed it I font recall him promoting or even mentioning any of the cables in use from audioquest.

What ones does he mention and when??

The ayre electronics gets a mention though

 

[Infiniteloop]

There is no reference in the whole video to any specific cable in any way. It's not about cables

The reason the sound changes is because it changes the video is filmed by a German guy who is not related either.

These types of videos will get more and more frequent it's inevitable and it's great because I couldn't go to the Munich high end show but still get a sneak peak of what was there.

Even the cut video at the end you can hear the difference between the niagra and no niagra in use. It's a video about that product and just highlights a few things on the way.

Don't worry if it's below you - that's how your comments read

OK I've just watched a few little bits of it and as expected it's just some guy waffling on about your usual audiophool pseudoscience rubbish.

As for the trumpet bit they both sound the same on my tablet. I didn't bother using my headphones because as I said before, even if I do hear a difference it would be meaningless as there are several different factors which could be causing the difference.

I listened to it using my MacBook Pro and Bose noise-cancelling headphones. I have to say that I heard quite a significant difference. It's also interesting that he played the better sound first and the worse one after it. - Usually things like this are presented the other way around.

No of course you can't because it's just an amature YouTube video of unknown origin.

Oh yes of course so many variables still same result its a guy filming if you look at his other videos on you tube they are completely non related to audioquest or the company or the guy promoting

My bet is he sat Down and filmed it and start running low on mem or battery towards the end. If you watch the video stays constant through that whole bit.

But of course he has bothered to edit it after to change the sound.

It's ridiculous pessimism of the highest order and you know it as well. Just being awkward to not say yes he showed a difference in that demo several times

Why this doesn't change my view on the subject I can admit that is what happened

That is not difficult but has to a relentless battle with certain stubborn people on here

You're right. Teachers are paid (****) money to try and get basic science through to people who for some reason often refuse to understand, but I'm doing all this for free, so I officially quit the role. Someone else fancy a go, please be my guest.

I'm bored with this now. There are only so many times you can say the same thing although the OP seems happy to keep repeating himself.

For Ellis and Thomson ...

Whether AC or DC, and whatever 'direction' you like your current to flow, best of luck and enjoy it.

2. Use Audiodiffmaker to see if there is a difference

Recently I suggested this in a similar context over on the PFM audio forum. According to one of the bods over there, the time alignment in Audiodiffmaker doesn't work, so the whole tool is next to useless. (BTW this guy is an experienced electronic engineer and an "objectivist", and it's certainly not in his interests to diss Audiodiffmaker.)

If that is the case why often is there no sound then?

Do you mean why is no sound audible, or why is there no sound? If the latter, I'm not confident the premise is correct. In either case, I can't answer the question, I'm afraid.

I'm saying if the timing is out, why is there no difference, as you play it back and if there is nothing then they have cancelled each other out. Does not make sense to me.

It may be that the timing alignment is just unreliable: with some musical samples it might work, with other types of material it might not. In other words the negatives may be genuine negatives, but some of the positives may be false.

 

[BIGBERNARDBRESSLAW]

The answer to the question is:

1. If you think cables are directonal, use them in the directon you feel sounds best.

2. If you think cables are not directional, just use them in any direction.

Can we all stop now?

I don't blame people for not reading the whole thread but most people didn't even watch the video before they started on here

This thread was supposed to be about the video nor how speakers work or anything else.

But things get twisted to win the online war. Roaring with someone about hifi only thing better than listening to it.

If you lot turned your cables round the right way we would never hear from you again as you would be spell bound by how good music is supposed to sound

I understand what the 'scientists' are saying, but I cannot deny that I do hear quite a big difference.

I have found a similar effect with USB cables. I have a reasonably good quality Chord USB cable in my Devialet based system but I prefer the cheaper cable in my Valve-based system. I have tried both cables in both systems too. I know the theories about why there shoudn't be a difference, but to my ears, there is.

By the way, if you go on to the Devialet Chat forum, posters there will leave you in no doubt at all about whether cables sound different........

 

[RobinKidderminster]

Agreed the thread/video proves nothing but it has provided some interesting information. Most of all its shown the attitudes, talents and knowledge of a few here. I still didn't find any reference to the quality of YouTube in comparison to "hi-fi" standards but an interesting battle (at times).

2 cables for you to look at
Jcat or ppa usb made by same person - these are honestly exceptional

Then there is computer audio design expensive but patent awarded design.

Demo at Bristol was easy the cleanest sound there into harbeth
