This is the correct audience to ask about 'zebra' wire.
Initially thought it to be a crafts wire but the search results all look like ISM.(industrial scientific medical)
It's available with gold or silver plating and high purity copper core.

I'm still intrigued back a few pages with those speaker runs using a solid return and stranded high side.

I'm sure that's the case.

To me, it has to be repeatable, verifiable, built upon or an extension to existing repeatable and verifiable work.

You need to use your "science" as it were, build a testable entity, show positive results which others can verify. All that with adequate controls.

I'm rather confident that the items you've mentioned cannot survive close scientific repeatable scrutiny, but am open to any valid test data you could provide.

I cannot simply take anecdotal accounts as science, to me that would be faith based.<snip>

So we have something in common, as these are some basic rules for doing science or scientific progress.

The difference seems to arise over the question what to do with assertions not backed by scientific evidence.
At that point some people are obviously more than willing to sacrifice their scientific approach in favour of their beliefs.

Extensive use of the playbook of eristics starts and search for truth is replaced by the urge to fight.

@ Rick Miller,

This is where the phrase started (Daniel von Recklinghausen) and it was slightly changed by someone I know.

There is a nice collection at the AES pnw section site:
Laws For Audio Engineers

including the original von Recklinghausen "law" . At that time iirc the debate about measurements and listening impressions and von Recklinghausen was strongly advocating an update of the IHF measurement catalog to get a better correlation between the objective and subjective side.

I found/find it a bit inconsistent to mark pointing to "stress" (not to detect, or not to consider it, is a flaw in the experiment/setup) as "excuse" - although we know due to experimental evidence that it is a strong confounder - while searching for other flaws is accepted as search for "explanations" , isn´t it?
'Stress' is the usual explanation offered when golden ears fail to hear a difference in a blind test. I merely said that I would not use that explanation myself.

So far you didn´t tell us what number of runs would be sufficient.
I would leave that to someone who knows far more about statistics than I do.

Really, you think my questions were an attack?
I hope pointing me to the above inconsistency helps a bit against your impression. Further in the other thread you posted that "it helps when no fincancial interests....", so it is imo an obvious question (not answered yet).
I was going by 'tone of voice', but perhaps you always talk in an apparently aggressive manner? Some people do. Forgive me if I misunderstood.

I can confirm that I have no financial interest in audio. Some years ago I was paid for a set of three articles in Wireless World about the complementary feedback pair but that was about how they work, not how they sound. I have never made claims about my ears so I have no reputational interest either. Perhaps other prominent contributors to this thread will make similar statements of interest now?

Don´t know if am within these "some people" , but what about that their view could be correct?
It could be, but I suspect this is unlikely. My view (call it a "belief" if it pleases you) is that we more or less know what we need to know for good audio, and have done for some years. Any new information will be at the margins and only provide for minor improvements which most people will not hear - including most who fondly imagine that they will hear it clearly.

Does circuit theory have to be wrong, if someone is able to hear a difference between two cables? You know better,i guess
In some cases, yes (e.g. silver vs. copper with identical geometry). In most cases, no because a cable which sounds different from an ordinary cable is inferior electrically even if it sounds 'better' to some people.

"We can hear everything we measure, but we can't measure everything we hear. Let your ears be your guide."
No. We can measure things we can't hear. If we can hear it then in principle we can measure it, even if at present we do not or do not yet know how to. Ears are a good guide to what pleases me; they may be a poor guide to anything else.

I can see the point of getting cables off the floor,
I can't. A suspended wooden floor with air underneath it would provide a better dielectric than wooden blocks, even if I thought that was relevant to speaker cables.

I wondered who would blink first in your little contest.
 
Rick please don't get me wrong, I have no problem with your process and whatever gives you (and I mean you) more musical enjoyment is fine.

You have to remember that Charles said here that cable lifters were the single most effective tweek you could ever do. He was quite adamant in fact, but consider what the cable was lifted from was irrelevant, I guess air is good "stuff" is bad. It also was presented as a fact that should be true for everyone. He even implied that you could forgo a speaker upgrade (even $1000's of dollars). How silly does this stuff have to get?


I have a gut intuitive hunch that ultimately this will be fully understood , even by the aes. Hint: Specific Organic material.
 
That said, there are significant reasons that a line cord can alter a system response.

That sounds interesting!

I see over on the power cable thread that you have significant experience in that area.

Provided it doesn't require you to get entangled in screeds of theory, would you possibly summarise the significant reasons why a line cord can alter a system response?

Perhaps the power cable thread is the place to post the summary. I think I am correct in saying that you haven't already done so on that thread, but am happy to be corrected.

Note that I ask this as a matter of scientific interest, and am not attempting to stir things up!

Thanks.

A system where two rca cables connects an amp to a preamp, with 3 prong line cords, establishes a ground loop.
If the preamp sends a signal through one shielded cable, the low frequency current return will be typically through the bonding ground, with only some of it returning to the preamp by the shield of that cable.

At high frequency, the current will return by the shield of the rca being driven.

How the current returns to the pre will be dependent on the reactances the signal encounters. That will depend on the resistances, the loop area of the line cords with rca's.

Without control over the path of the currents, even moving the line cords around can affect the system.

There are diagrams in my gallery.

Granted, the diagrams are five years old, but I suspect those pesky Maxwell equations still hold..

Very good info J. thanks for sharing,
 
All we need now is for Mr Merrill to show up to complete the show and the inevitable closure of yet another pointless thread
You called - how can I help? :D

Ah, maybe all we need is for Mr Wurcer to expand to detail the warnings about the difficulties of blind testing for small differences.

You already know my views as I've detailed them but I've never seen Mr Wurcer's warnings on this topic, have you?
