If you read more carefully, you'll see this is a conditioning cord.
If you properly search, you can discover how a power cord can make a measurable difference. Given some of these manufacturers have competing products, you'll have to put it in the leg work yourself if you're really interested, rather than trolling.
]]>Given the only response you'll care about is a measurement, go do the work yourself.
]]>You could take a couple minutes to read the review and look at the manufacturer's websites to find the relevant info.
Your goal is admirable, but everything has some level of coloration. Otherwise music reproduction would be easy. If you spend time working on improving your power, you may realize how difficult it is to aim for your stated goals
]]>I'd really like to see one of these reviews use a proper piece of scientific equipment to support the claims. Something that gave objective measurements such as a network analyser. A colleague of mine worked as a technician for a well known audio publication and they actually used high-end analysers which tested claims of manufacturers, rather than just relying on their own objective bias.
]]>How does skin effect have any impact on a power supply? Please enlighten me?
]]>Except all it says is "dedicated 15 amplifier" (I presume that was intended to say 'amp'). Dedicated sockets is irrelevant when city power is unconditioned.
]]>Skin effect at mains frequencies? Really?
]]>Thanks Anon.
I don't know about the internals of the cable, so cannot answer your first question.
As far as the K-S cables, sorry, I have not had a chance to audition the new Realization line yet.
So far in my cable adventures, none come up to the amount of weight imparted by these Stage III wires. They seem to be in a class by themselves.

]]>"A common misconception regarding power cables is that they represent the final link in the transfer of power after traveling through miles of power lines and in-home wiring. The power cable is actually the first two meters of power wiring that the audio component sees — electrically speaking. In effect, the power cable is an extension of the transformer in the component’s power supply.
Shunyata Research has developed advanced conductor geometries, electrical contacts, power connectors and junction-to-junction bonding techniques with measurements provided by our exclusive DTCDTM Analyzer. Shunyata Research’s NR Series power cords have built-in noise filters that measurably improves CCITM (Component-to-Component Interference) by reducing conducted power line noise and radiated RFI/EMI interference. Some of the key features of our power cords include: pure OFE (Oxygen-Free Electrolytic) copper; VTXTM ‘hollow tube’ wires; CopperCONN® connectors made with pure copper contacts; and built-in NR noise reduction filters."

"Alright...
With power cords its all about voltage drop across the cord. Some of that is at 60Hz, and some of that is much much higher- well above 30KHz-100KHz depending on the power supply in the unit with which it is being used.
I’ve seen a 2 1/2 volt drop rob an amplifier of about 30% of its output power. The cord was rated for 10 amps, and the draw was about 6 amps. This measurement was done with a simple 3 1/2 digit Digital Voltmeter.
The more insidious problem is high frequency bandwidth. The power supplies of most amplifiers have a power transformer, a set of rectifiers, and a set of filter capacitors. The rectifiers only conduct when the power transformer output is higher than that of the filter caps. So:
When the caps are fully charged the amp is able to play. As it does so, the caps are discharged until the AC line voltage waveform gets high enough again that the rectifiers in the power supply are able to conduct. Depending on the state of charge of the filter capacitors, this might only be for a few microseconds or it might be a few milliseconds. Either way, the charge is a spike which has very steep sides- and requires some bandwidth to make it happen.
If the power cord has poor high frequency response, it will current limit on these spikes. This can result is subtle modulations in the power supply or even a sagging power supply voltage.
Romex wiring found in many buildings actually works quite well. So it really becomes all about that last few feet and also how well the power cord is terminated- molded cords generally are not terminated very well. If the ends of your power cord get warm after a while, you know you have a problem!
This can be measured, its quantifiable and also audible as many audiophiles know. Anyone who tells you differently probably has not bothered to do any measurements- please refer them to this post.
I can go into more depth but this is it in a nutshell. Incidentally, Shunyata Research is refining an instrument that does a more in-depth analysis of what this is all about. At the link you will see that their tests essentially confirm what I have said here.

]]>Do you know if the stacked dual conductors have any space between them? It seems odd that the Proteus and Leviathan both use this design, that should reduce the ability of ribbons to limit skin effect. They both clearly increase conductor size and the amount of the damping/shielding filler.
Did you ever compare the Elation and Realization cables to each other, or Realization to one of the Stage III?
Thanks!
]]>Okay, but this is a simple question. What's the value of a 15k power cable when your home power isn't conditioned?
How can a power cable physically change the sound? You encourage people to spend this money, but do you have any quantitive measurements of the actual changes to frequency response that might actually make it objectively better?
Or is it confirmation bias?
