I don't believe cables make a difference, any input?

Ahh, yes I forgot, pseudo balanced cables
I used them a lot in my younger days
Yes, a different kind of "directionality"

Still have a pair
I dont know why it works, may be noise related
But it does make a difference which way you orient a pseudo balanced cable
At least the difference has always been clearly audible to me
Tho orientation of a pseudo balanced cable is not always the same, but depending
Sometimes those arrows point the wrong way :clown:
 
Only if you use a nonstandard definition of "hear."

Fault. Second service.

"I, Brooke Turner, do perceive by ear differences between cables in normal sighted listening conditions." Works for me, no loss of honesty.

Of course, you can make the Humpty Dumpty argument...

Of course I can, but I prefer only to use it in a sticky spot. You played your Humpty Dumpty card and squandered it. The way things are going here, mine isn't likely to see light of day for a looooooooong time 😀
 
Hi,

No, directionality started when smart engineers found a way to decrease hum and noise in interlinks: by using an additional screen, in addition to the 'ground' screen in the unbalanced cable, and ground that additional screen only at one end.
To maximize the benefit, the side were the ground was connected should be on the sending/source side. To help remember that they put an arrow on the cable, supposed to point from source to receiving side (amp).

That perfectly sensible developement was subsequently, as often happens in a fashion industry, taken up by marketeers to sell 'directional cables', and, as so often happens in a fashion industry, the unsuspecting masses fell for it.

Directionality of an interconnect and directionality of wires are two unrelated subjects.

Cheers, 😉
 
I have two cables with arrows. I'm thinking of drawing more arrows on them. They have to be faster then, huh?🙂

Joke aside, I have not heard any significant difference when shifting directions. More over, I once had one of them connected wrong for about half a year, changing direction made no detectable change. Following the claim of some people here, it should be easier to hear differences when one has gotten used to a "sound" for a longer period.

Thankfully, I can't "hear" cables. I worry more about the drawbacks of loudspeakers.

The speaker is where most of the masking takes place. Also, changing listening levels sometimes will help discover different things.
 
There are many places and conditions where cables do make a difference. In many cases when the difference is very significant, probably such differences are due to diffeciency in design of either driving or receiving electronics equipment just like the effects of the little pigtail in the "groundside electrons" thread. The further away from a pure voltage model the interface operates at, the more critical impedance needs to be taken into consideration in any part of electronics.

Yes that's true. But one should remember that in all but the most pathological cases, that voltage model is valid in the context of the cable impedance.

Talking to Dr. van den Hul (eat your heart out JC 😉 ) a few weeks ago, he told me his carbon cables have a resistance of about 28 ohms per meter. Even with such an extremely high cable resistance, one can argue that there is no audible impact of resistance period, except some possible very minor level differences which are easily corrected by twiddling the volume control, of course.

However, Ed Simon did a measured test of a number of interconnects and found some of them very directional, even obviously audibly so. He published this in 'AudioXpress' Nov. 2009, and it has been put up on this thread.

John,

A correction. I understand that one way to read my draft would imply I listened for direction. I did not, I compared the best and worst measuring cables. I might have been able to hear a difference between my best measuring cables and the worst, that is at my limit. That is a much greater difference than the front to back measurement.

Other folks have measured differences in cables also. One of the fads in ham radio is to used a network analyzer to see which way RF cables work best.

Note! Cables not conductors! The difference could be anything from the way connector pairs mate to actual crystal structure in the conductor.

So there is nothing really new here. My article was on how to measure the distortion. The goal being to make it easier for anyone to test cables to see if they wish to spend lots of money on a magic cable. There are some differences that are real and practical.

Real gold plated connectors work better than other types as they do not have oxidation problems. Solder joint or crimp quality is an issue. Shield design can be important. Connector dimensions and contact area count.

Can everyone hear these problems? Well a cold solder joint or filthy connector can cause no signal to pass. So most people could tell a difference. It is opinion if that is worse or an improvement and in some cases it may be better. (Humor for those lacking in common sense.)

If two cables have the same LRC will they sound different? Maybe, because they can have different distortion. Can you tell the difference?

If you are playing MP3's pretty much so no. 16 bit CD's over most "Name Brand" gear (Sony, etc.) probably not. 24 bit files with a high input impedance amplifier and a whiz bang system, now you are getting into the area where cable distortion differences are at a maximum. Can that be heard? If you tell me you cannot hear a difference, I will believe you.

I am surprised that you actually talked to him, Jan. I thought you were against his ideas. OF COURSE, the carbon cables have more resistance, BUT if it is virtually perfect, especially at low levels, then it is an advance in wire technology. What I hate is the TERMINATION of these cables. I have had samples for decades.

A lot of people talk about various material and structure, much of which I have not experienced. But just within my own experience, the more simple structure seem to produce a cleaner and accurate sound. There was only one exeception which was Randal Research cables. But now that I know a bit more about the interfacing electronics, I'd probably take some time to plug them back in for re-listening. Cables with too many strands always seem to give the sound a furry edge. I'm sure carbon cables are going to provide a well damped clean sound, but what it does to the low level detail, I kind of wonder.

As demonstrated by...??

16 bit CD's over most "Name Brand" gear (Sony, etc.) probably not.
Ahh yes "Mid-Fi". You have evidence that 16 bits and "Name Brand" gear "probably" audibly suppresses cable distortion (vs a "hi-rez" system)?
Let's see it.

24 bit files with a high input impedance amplifier and a whiz bang system, now you are getting into the area where cable distortion differences are at a maximum. Can that be heard? If you tell me you cannot hear a difference, I will believe you.
And if you tell me you can hear a difference, I will believe you.
I just won't expect any demonstrable proof (to RDF's, Jakob2's, John Risch et al robust standards) outside of an internet connection 😉
 
The opposite could just as easily be said. Why not try to avoid logical fallacies?

No,it couldn't.A Pioneer cheap amp for example can't be in anyway better than say an audio research.When you talk of serious mass production manufacturers,talk about serious high-end manufacturers too.There are many of both kinds.I have never heard of a mass production manufactrer to claim that their low cost equipment sounds better than any specific high-end one.This is one of the very few places where you can read such claims.

I stated it could be "said". That doesn't make it a fact. That was my point.

I think too many people try to read into what is being said instead of just reading what is being said. Again, it is logical fallacy.
