Virtual Dynamics Power Cords

This is why it is FRUSTRATING!!! you guys don't get it. Get a copy of the latest code cycle, NEC 2002. you can LEARN things based in reality. Ampacity IS a word used in the NEC. all this happy talk, think outside the box? Another marketing blurb, shows you watch and hear too much nonsense, and it corrupts your thinking. People trying to convince me they can hear the sound of an AC power cord, and because I don't consider it anything but nonsesne, this bothers those that are beyond logic. Get some NEMA, some NEC2002 literature, it will set your mind free. It's called reality. Wiring devices with audio qualitys?!!!

My inquiry about "ampacity" was merely grammatical, not electrical. It sounded like a made up word, that's all. I had not seen it used elsewhere, so I was curious about its origins either way.

Another particular tome that may "set your mind free" CE, is called the Dictionary. Crack one of them open once!

(sorry, couldn't resist)

All wurds where made up. DUH!!!! The didn't grow on a pear tree. Which dictionary?, I have been told some have more res than others...some give better definitions than others. is this true? Look up snake oil, scams, etc.

Oh come now, everybody knows words do in fact grow on pear trees! Strange but true. I have a pear tree in my back yard and every year I add some new words to my vocabulary from it. Plus they are quite tasty!

CE, I know where you're coming from and agree with the gist of what you're saying, but you have all the grace of a bull in a china shop. You're coming off like a simple troll who just wants to piss folks off. Hifi is kinda like church. The parishoners aren't too keen about some dude coming in during mass and yelling "There is no God! You fools!" That's about all you're doing here.

I agree that the marketing of audio products such as power cords and the like definitely carries with it the smell of shenanigans, but of course you don't have to buy them. Potentially dubious ad copy and bending\breaking the electrical rules which you continually point to is something that can be debated, but stating that people cannot hear what they claim to hear isn't as easily challenged. Perhaps there are other reasons we should examine for what people perceive as changes in the sound for which there is precious little scientific backup.

I've been influenced by cable hype myself and so far haven't experienced anything that lives up to any ad blurb out there. But it's easy not to be fleeced - just don't buy thousand dollar cords! Simple! Heh!

There is no GOD....

Actually I would hope that if there were "supreme beings" that it would be on the order that the Greeks and Romans thought of them, that is many gods.

So they could party and socialize.

The crap that goes on in the Catholic church (and I go regularly) is so paganistic as to be funny to me.

At least the house band is great

This is why it is FRUSTRATING!!! you guys don't get it. Get a copy of the latest bible circa 2003. you can LEARN things based in reality. God IS real you just have to have faith. all this happy talk, think outside the box? Another marketing blurb, shows you watch and hear too much nonsense, and it corrupts your thinking. People trying to convince me they cannot believe in god, and because I don't consider it anything but nonsesne, this bothers those that are beyond logic. Get some faith, some bible literature, it will set your mind free. It's called reality. Thinking that god does not exist?!!!

20Khz on a power cord. What kind of AC line do you have? Mine is 60Hz. Voltage drop so what? A properly designed amp/pre amp can deal with it a few volts ...do you think .1 OHM or so of negible resistance in a wall outlet to cord cap, is gonna effect the sound of an amp...you are reading too many cool ads. You just don't get it.

Yes, thats correct 20kHz CURRENT, not voltage. I'm afraid you don't get it yet. The di/dt can cause several volts of drop during music transients across the 6-foot cord. This can cause a droop in voltage in the power supply depending on the inductance and type of the capacitive storage inside the power supply of the amp. If there is significant inductance and not enough high-frequency decoupling capacitance, these drops can be significant. If you are not an engineer, I don't expect you to understand this right away. It is a complex power-delivery problem. Most folks believe since the impedance of the power source is so low, that only resistance is a consideration. This is simply not true, inductance plays a large part in the power delivery as well. Once you have heard the benefits of a low-inductance power cord, you will be a believer too.

In the last 6 feet of cord..utter BS, and marketing nonsense. a properly designed power supply in the electronics can operate just fine, within a range of input AC. Yeah, I need a #10 cord to power a device that draws about 8A...when cranked LOUD!!! Stop the insanity. there is no sound benefit in these assinie power cords or interconnects. Why is electrical design and facts somehow different for consumer audio, than any other electrical device? I think, just becasue it can be....why do the dozens of these cord makers all have some magical shape and insulation, each claiming superiority, and they are all goofy different ovals, squares, twists,bi furcated, wrapped, double wrapped...nothing like a 1 inch round cord, with like #16 conductor in it...and all this wrap is improving the sound....any documents on your research on this 20Khz AC on the line cord?

Can an ac transformer even pass 20kHz? In other words, isn't the xformer inductance higher than a cheezy power cable? I'd expect the cable to have a much higher bandwidth.

This 20Khz current is effected by the last 6 feet of wire, but the 60 feet of NM wire going to the service panel, doesn't matter. how does this last 6 feet fix the previous NM, just solid house wire, that is so bad? I don't see a freq rating on the Leviton or hubbbel wall devices? Are these cords UL listed by chance? ETL or CSA? I would think so since they are at a premium price, I'm sure they have been submited to UL for testing?

My Milwaukee Sawzall has a detachable cord, should I replace it with a high performance, better cutting AC cord type. Please advise me on which one will make my power tool, perform better? OH, wait, Audio electrons only get improved, not motor electrons.

I think a good power cord might give it enough clean juice to be able to drill through that thick head of yours.
