It is a speaker cable, not a preamp one.
Unless you use a Quad ESL-2905 and a very (very) special selfic cable, i don't know how you can get such treble losses, with a cut-off frequency of 1kz.;-)
But, you misunderstood one other point, it is not level curves, but "Significant musical signals" curve. That's why you will need the Significant musical signals meter i was talking about. I can build one for you if you want to win the 1 million $. (Pm for the price, but it will be as expensive as the *danceable cable*)
BTW: I just discover an other part of systems witch deserve to be tuned after cables.
Fuses.
I just read an article, They report astonishing differences in the sound with different fuses. Not some 'golden ears' differences, but obvious ones.
So, in September, i will stop to listen to cables, and begin to listen to fuses.
A very difficult study, as the sound of fuses interfere with the sound of the power cords, as everybody knows.
[edit]After that, i will be ready to buy an amplifier for Christmas.

It depends on where the fuse is located with respect to your speakers.
Is the fuse at the power station, or at the HV transformer, or at the local LV transformer, or at the incomer just before the distribution board?
I somehow doubt that the power company will allow you access to swap fuses to hear/measure the effect you allude to.

Bridge pluse test setup errors. As I stated earlier, most do not know how to properly measure L at such low levels, they do not understand the issue of "current path". Heck, I still see books which claim a foot of single conductor wire has 1 or 2 microhenries of inductance..clarly false, but still lives on it's own.
Yes. I've seen it many times. Given that it's a different discipline, I've seen many people mess up L measures. I've also checked the "fix the errors then resubmit" box may a time for bad L and/or C measurements put into a paper being reviewed.
Yes. But at the macro level and room temperature, the electronic properties of the metals have not been changed to a point where it can be measured, even at 10 power 10 accuracies. At 4.5 kelvin, yes the mean free path may be changed, but nobody keeps speaker cables at that temperature.
Agreed. But, wasn't the claimed result of that listening test...that a difference was heard therefore established?

If you read the accompanying reference articles, you will see that Pear ultimately refused to test their cables in the double-blind test. Why? Because they knew they would lose. I have read several double-blind test for speaker cables and ALL fail to prove that there is any audible difference between regular zip cord and the more exotic and laughable "audiophile" cables. You can do your own search to find tests and their results, they are easy to find. This thread has so far been very entertaining to see actual so-called "scientists" and "engineers" spout their technological BS, and the sad part is they seem to actually believe what they are saying. At least I know now whose advice on this forum NOT to take. Continue on gentlemen, so far it's been a million laughs.
Whew, I'm glad I finally got THAT off my chest. ;^)
No, it's both. They claim their measurement is of a system using 16 feet of interconnect cable and 14 feet of speaker cable.

That's strange, it was there last night. Oh, I see what happened, can't upload MP3s. It's attached now, but I put a .zip extension on it. Just change that back to .mp3
Be careful with your tweeters.
Yes, I've noticed that. And I was about to buy this bench DVM yesterday, it's on sale for $80.

What really intrigued me were the 1µA and 10µA AC current ranges. But at that price? I just didn't think I'd get anything but noise.
Hi,
I stated it as insurence againt being mistaken by a cable vendor who posts here and who's "cryo" cables use a very different process compared with the one we tested.
I agree, it is stating the obvious. It was as Santa Esmeralda put it "Don't let me be misunderstood".

I don't understand. Two people, on this thread had talked about line transmission effects in wires in a scientific way. Means you can understand, measure and reproduce.
They never (if i had read everything correctly ?) had pretended the changes you can measure above 1MHz* affect the sound quality in any noticeable manner, as far the equipment around is correct and with domestic lines lengths ? Most (IE all but one) of the other engineers or technicians here just entertain themselves, sometimes using absurd
, with this very funny thread. They of course, use ordinary cables for their systems and explain why.
The scientific approach is not to *believe*, but, as long as you believe in something, to study (isolate and measure) phenomenas till you can advance evidences on your assertions. Right ?
I wonder why, in this matter of magical mystery tours of cables, so much people oppose scientists and Audio lovers. Did technical studies supposed to make you deaf ?
Laws of music are mathematical. Harmonics, periods. And science the sister of art.

Actually, I seem to recall something about failure to agree on test protocols, or something to that effect. Steve could elaborate a tad I believe.
Actually, I've never "so-called" myself as a scientist...my wife would never let me out of the house with that kind of wardrobe..
And, what makes you think that I believe what I say.😕 So far, I can still bamboozle the grade school kids on tours...
I don't recall many giving advice here, just lots of interesting discussion.
Been bustin at the seams for a long time, eh?
Cheers, jn
Yes, if they are curved. No, if they are straight and uniform. That's why speaker cables are usually hanging on identical poles that stand on equal distances.

yahbut..yahbut..
Even with the poles, aren't we dealing with cosine hyperbolics????
Maybe your electrons were taught COSH in skool??

Pear did withdraw their offer to provide their cables to Michael Fremer who was the one who had accepted the Randi challenge.
It had nothing to do with failure to agree on test protocols. The discussion of protocols hadn't even begun.
Then Randi used Pear's withdrawal to disingenuously pull the rug out from under Fremer and declared the challenge over, even though there were still two other cables on the table at that time.
I lost all respect for Randi after that.

I use my Wheatstone Bridge to measure anything under an ohm, I trust my Cambridge LC meter to 50pF and 10nH. Neither meter cost me a penny. Not being a scientist I have no use for measurements below those levels...very often.

I only hang mine in the imaginary plane, hence they aren't susceptible to your run-of-the-mill distortions and such... they just seem to VANISH!!

The whole exercise is pointless IMO without differentiating between difference and preference. I also still think Randi was lucky, he might have let MF pick speakers with known pathological impedance issues.
I see you so call yourself an engineer, very technical criticism I think I'll cry.
