Funniest snake oil theories

The center image is fixed by your head location. That cannot be discerned by humans. What you may have done is discern the images off center, and assuemd it was the center that moved instead of the side images.
So how can side images move if the cable has no directional effect ?.

The center image can also contain depth information.
A perfect system will portray central image as a vertical thin sheet extending backwards from the front panel of the loudspeakers.
That's the clue.

That is the wrong question to ask.

You perceived a change and immediately assign it to wire directionality. That is certainly not the scientific approach to the problem. Nor, does it consider the reality of the physics and electronics.

Instead, consider what within the program needs to change such that side images move with respect to a central mono image.

What distinguishes a side image from a central one...that is the question that needs consideration.

edit: to your question...how is the ground current path from the input jacks controlled back to the IEC?

What return currents?

In my gallery is this:



Signal current which flows through the IC core has to get back to the source. It has two paths in this pic, through the shield, and through the line cord.

DC, the line cord is a better path.

RF, the IC is the better path.

Within the audio range, it is frequency dependent, simple model in the pic.

Sorry.

I have to say, your link was fantastic, it clearly shows how the return current depends on the paths and the frequency.

The ever increasing speed of digital circuitry and the increasing RF pollution has mad understanding return currents critical if you want to do PCB's properly these days. Also a firm I worked for did some work for Daresbury in the early 90s, met a mad physicist whos views on the term Ground were unprintable, he taught me to always think of it as a return path, and 0Vs some arbitrary point in a circuit. Never looked back

Stereo means two channels.
Both signal paths need to be identical.

Dan.

No, if both signals are identical then it falls to mono. Stereo effect is produced due to the differences in both channels.

You and Frank are hittin' the pipe when it comes to things like this.

His idea of removing frequency response and dynamic range to deem poor recordings playable and alive is just nonsense. AM broadcast quality sound is not lifelike.

No amount of snake oil or tweaking will make bad recordings good. Removing the resolution from a system does not make it sound better. It is just the audio equivalent of feeding a 1080HD screen with 300 scan rate standard video and hoping it won't look grainy.
It all starts from the source and if the source is poor then everything after is too, only amplified.

Also, cables are not directional.

You and Frank are trolls.

Sorry to let more gas out.
 
I believe your first statement is incorrect.

Return current will run as close to drive signal as is physically possible. As such it will run in the shield of the interconnect cable.

That is not quite correct. Return current will take the path of lowest impedance.

At the lower frequencies, that is the lowest resistance path. As the frequency goes up, the inductance of the line cord path makes it the higher impedance path, and the shield takes over. So your statement is in part accurate, but only when the closer path is the lowest impedance path. At audio frequencies, that is not necessarily the case.

Check out the link marce provided. Notice the drawing (figure 2) showing the shielded cable with the grounding strap. And look at my gallery link, I've gone a little further and actually provided the equational relationship for such a setup, one that allows others to model.

It really does that, and is easily demonstrated. Tom Van Doren demo'd that here about 3 or 4 years ago.

Return current will take all available paths.
