Sorry for the typo. Audial.

It's either auto-dial, or audible..(please select the second choice.).

As for the person being discussed....

Both of you are correct in part..the guy may be smart, he definitely is in it for the money...

But making a power cord that is so ineptly dangerous that it should be banned from the market is not right. One funeral because of that unsafe design is one too many.

Cheers, John

It is easy to make the mistake of assuming that because a guy is technically savvy about one thing, maybe even a genius, he is automatically savvy about everything else technical. Whether its John Curl, an acknowledged fine designer of audio amplifiers embarrassing himself about the quantum physics of electrical conductivity in wires or a guy named Lawrence N. who was an expert at using an Eximer Laser but didn't know beans about chemistry and insisted on installing normal carbon steel tubing and ductwork for the fluorine supply and discharge because his department didn't have a sufficient budget for stainless steel, many people blindly believe in them. The safety guy who sat mute at the meeting because he had a personal war with my division manager later admitted that in a similar installation, a small leak had done a quarter of a million dollars in damage over a weekend in another lab that another scientist had built the same way.

I don't know what role this guy played in the design of electrical control systems in high performance aircraft and these may have been low voltage power limited systems anyway, but extrapolating to the design he is marketing for a 120 volt 15 amp power cord makes me feel he has gone way out beyond his depth. It makes me suspect he was a technician who became an audio tinkerer, not an engineer. I don't think that even Jon Risch would ever propose anything like this.

BTW, to RGA who wants to know why I won't post at AA anymore, the last time I saw something this dangerous was a DIY posting at cable asylum for a power cord made out of coax and another using ferrite beads creating high impedence grounds. The guy who built monster speaker cables weaving 10,000 pairs of cat 5 telephone wire together and blew up his amplifier (I say he built a giant capacitor which sent it into spontaneous ultrasonic oscillation) didn't inspire any confidence either. Some of their proposed home brew electrical wiring projects for their houses were nightmares too. Scary.

Read my input on this- Pierre Sprey- WHO IS HE.
I have some links from a google search, including the F16 story.
Not to worry. It doesn't look like he designed an inch of that aircraft from reading the history where he is mentioned only once as to his position. He was in the Pentagon assistant somebody to sec def. He may have been instrumental in policy and defense needs of the F16 but actual design of the aircraft, I seriously doubt that, not from any of the links found.

and the F16 link. He is mentioned but once there. A policy wonk?

lol Actually it is audial, or aural. Generally, people who are in business are in it for the money. I have no problem with that.

I don't know it if has been accurately demonstrated that his powercord is inherently dangerous. I'm certainly no engineer, but I don't think as a businessman that he would open himself up to that sort of liability. I have talked to him several times on the phone about a couple of products. I'm sure he would be more than willing to discuss the finer points of his powercord safety.

I don't know about you John, but I'm in no mood to train him.

I don't know about you John, but I'm in no mood to train him.

So, was I correct in thinking that you have no experience in the audible differences amongst different powercords?

[skeptic]

You're right, they all sound the same to me.

[wiseburro]

You're right, they all sound the same to me.

That's cool. At least you have tried a few for yourself.

[wiseburro]

You're right, they all sound the same to me.

That is a very interesting comment for someone that claims, "That strongly suggests to me that the need for it in a consumer audio amplifier is completely bogus."

They ALL sound the same to you? Are you telling us that you have tried a few aftermarket powercords? You wouldn't be making an unsubstantiated claim now, would you?


First, you say I'm right that you have no experience, then you claim that they all sound the same. lol

I would hate to suggest that you are lying, but your statements don't add up.


Maybe we should address the phenomena of engineers needing to pontificate about subjects that they have absolutely no experience in. Why do you think that exists?

? Are there any high end audio power cord design engineers out there that can explain how a three foot cord affects a 60 Hz 120 VAC signal in a way such that it improves the sound quality of anything.


(I don't expect anyone to ever reply)

Why don't you ask this question of your beloved Pierre Sprey? Obvious to anyone he doesn't know. While you are asking this question, ask for evidence for his claims, not testimonials.

"Maybe we should address the phenomena of engineers needing to pontificate about subjects that they have absolutely no experience in. Why do you think that exists?"

Electrical engineers don't learn about electrical conductivity in wire by taking home the latest product Joe Schmo's Hi Fi Haven is offering this week. They start in a classroom by studying mathematical models of wire, the circuits they are connected to, taking data in laboratories, analyzing it, and drawing scientific conclusions. If they are still interested, they contact people who actually make and test wire like Belden. They don't gain anything from printed advertising literature or hype on the internet. That way they wind up putting their money in their education, not wire for their stereo systems. Now how do YOU learn about it.

[mtrycraft]

So, was I correct in thinking that you have no experience in the audible differences amongst different powercords?

You have any evidence that any of them have an audible sound to it? Don't try too hard looking. There is no evidence, zero. Neither does Pierre has it.
So, what is there to listen to?

[skeptic]

Once again it is impossible to find anyone who has performed a fair test of any power cords or even has a suitable setup to conduct such a test. As I said in another posting, the only listening test I would now consider fair to even show evidence of a role any cables would play is not wire A against wire B but wire A against a shunt. DBT of course. If I were to set one up, I'd use make before break relays just the way I would with speaker cables. But then what do I know. PC Tower says engineers are too stupid to set up and conduct DBTs. So who is smart enough, clever enough, truthful enough, fair, trustworthy, decent, loves god and country enough to do the job? Lawyers.
