Who said it acted like a diode?

georgehifi resonse:
It’s the only technical non voodoo’ist explanation, if they (fuses or cables) are seen/heard to be directional.

First this thread is about cables, not fuses. For the discussion of this thread leave fuses out of it. PLEASE!

No doubt the diode theory makes it easier for you to disprove the chance cable directionality can exist.

Possible other theories that may be at play with cable directionality might be distortion in the cable caused by the conductor and or the type of dielectric used to cover the conductor. In one direction the distortion may be less than the other.

Apparently to date no one has been able to prove or disprove beyond a reasonable doubt using test equipment, that exists today, if cables are directional or not directional. I might also add to date, not that I am aware of, any such credible tests that prove or disprove ICs and speaker cables break-in burn-in with use. Do you believe they do? Now I am not talking about cheapo $2 or $4 dollar ICs. I am referring to good quality designed and built ICs whether DIY or name brand.

Here is a long and winding thread I found on AA. Note the posts of well known EEs and a couple of audio equipment designers. It appears bench testing of IC cables is not all that easy to do. You can’t just use a multi meter to test an IC or speaker cable. Other than maybe checking for continuity or DC resistance.

No cable warm up: proven by a Korean hi-end critique

Posted by koko (A) on February 10, 2002 at 15:21:02

Mr. Hyun, one of the most popular and highly respected hi-end audio critique at HIFINET, claimed that it is scientifically proven that there is not a thing like cable warm up or cable break in.
According to him, his claim is so firmly established by science that it can never be altered by future science.

He says that he himself measured RadioShack audio cables with a multi-meter. He used continuous sine wave tones on a test CD. He could not measure voltage difference between a new one, a several-day-old one, and a several-week-old one. He says that such test is SUFFICIENT to be a firm SCIENTIFIC PROOF of his claim because cable is electrically linear.

About HIFINET:
www.hifinet.co.kr
It is a true hi-end webzine. Korean hi-end audio importers provide its reviewers with Mark Levinson 380SL, B&W Nautilus 801, Sonus Faber Guarneri Homage, etc - true high-end stuff -.

About Mr. Hyun:
He has posted a lot of articles on technical issues as well as listening test reports. Readers can feel that he has high confidence on what he is talking about. He very often uses words such as ’science’, ’technology’, ’textbook’, ’NIST’, ’proof’, ’founded’, ’established’, etc.

Wasn’t Korea where they make the smartphones that kept blowing up last year? You know, Samsung. I kind doubt anyone’s opinion right off the bat who’s opinions are described as having a "high degree of confidence" or representing the pinnacle of high end audio. Gimme a break! That’s such an obvious Appeal to Authority it’s not funny.
Are you trying to be controversial? Don't we have enough controversy already? 😀

@jea48 > Where is your proof? Hard data? Any science supportive of your claims?

Nope. Not a bit. Just my own ears and opinions as were put down in this thread. I;’m not even gonna Google it to further support my claims.

I don’t care what any science, measuring equipment, theory, or electronic pathology states about anything in life. At some point later on someone will challenge it or refute it, or entirely oust it from popular opinion..

Years ago Coffee was said to be carsenogenic. Then it was red meat. Then it was red meat cooked very rare, then later it was said only the cooked well done meat was bad. And next it will be something else. Super. Fine.

Here is what I can control and attest to which is not my own truth but ‘the’ truth……. As I am able to perceive it.

Once a highly resolving system is established, one with sufficient transparency, exchanging in and out links, componentws, accessories, are all detectable merely from familiarity and astute listening sessions.

Pardon the vain attempt at humor from the power cord no matter how hard you push business. Sorry. It sounded funny to me. It still does.

I view the world at large by hwat, how or when I experience it first hand. It is said here on these pages repeatedly “try it for yoruself’. If a doubt exists.

If you can hear a difference, then there is a difference, in your opinion and may well be a difference in fact. It doesn’t matter what someone else opinion may be… in this arena it is the opinion of whom so ever is chief cook, and bottle washer which matters.

As erstwhile, frank, direct and open as are the notes of our experience we so liberally post on these pages remains, I am hard pressed to figure anyone, is intentionally stating contrary information or being outright deceptive. Passionate? Misguided? Confused? Possibly. But I feel the subjective accounts of members herein are so very often, quite genuine.

I refuse to be lead about by some bit of scientific data which essentially means nothing to me, when I can simply connect this to that and find out first hand what has changed.

So ‘skin effect’ and hole flow’, and aligning microns of the metals thru cryogenics are all just so much nonsense to me.. there is far more to this hobby than focusing on the minutia and remaining so pedantic we allow a past time to become an ‘all the time’ situation. As Riley said about that particular point in time, “the Thrill is gone.”.

There is gonna be smoke and mirrors everywhere there is advertisement. Marketing. Sales and salesmanship. Competition. Technology.

Big deal.

Corvettes have a load of technology built into them lately. How we find out if we like one is to drive it. Period. No other way. We have to experience one first hand.

Audio is the same exact identical thing! Experience things first hand. Damn the technology. Damn the hype. Damn, a lot of this stuff is freakin’ expensive! Lol.

New approaches on older themes occurs all the time. OK. Choose. Listen to them and give them a try…. Or ignore them. Its your pick. I tend to give credence to whomever… at first … and if it is an affordable thing to experiment with.

I’m never gonna know what its like to have a room professionally treated for acoustics. Never gonna know what it’s like to have a complete DCS stack of electronics.

I recently heard Ethernet wires make a diff in the SQ. Really? Well, I can find that out for myself. And will.

Do wires need to be run in? well, they sure sound different after a few weeks of playing than they did the first couple days.

I have more than one system in house. Meager as it may be, it helps me get wires run in with out wasting the main rig’s resources. Hell, the refrigerator does most of the power cord brning in duties.

I’ll plug whatever into the main affair and check it out. But always that day or the next, put it/them into another system to get run in for 7 – 10 days and recheck them. Some need more than 200 hours. Some don’t.
I’m very allergic to ‘placebos’. They do nothing to me physically, but emotionally I’m irritated someone actually thought nothing in a pill could alter my state of mind. Its like being cheated. IMO

So which way should wires run? Find out for yourself. There’s no other legit argument and what you discover regardless what other’s say even in consensus, will be ‘the’ truth, won’t it?

I pray this sheds more light onto my previous post.

I think we might very well have just witnessed the auspicious arrival of a brand new Juror #3 on the set of 12 Angry Men. Welcome aboard, soldier!

But there’s nothing there to hear. And you can’t prove there is.
And why can't you tell me why it would be a good thing even if it did exist? I've asked twice now.
