A/C CABLE MEASUREMENTS

Lets compare a regular IEC power cord that comes with audio equipment vs an ArtistCloner power cord.
Be aware that changes to the sound will happen and may or may not actually improve your overall sound experience.
REGULAR IEC POWER CORD 3x18 AWG
ArtistCloner (Not a Litz) IEC POWER CORD 2x12AWG and 1x12AWG
We are measuring the impedance of the cable between the live wire and ground for these graphs. This means that we are looking at its performance vs frequency. The true work of a great cable is to deliver the amperage necessary to drive the device and be efficient at the frequency (50 or 60Hz) of the A/C current. We can distinctively see that the two above measurements are not the same. For starters the graph on the left has a higher impedance overall (3 times more)which adds impedance (resistance) to the inflow of current from the wall compared to the right graph . A frequency of 50 to 60Hz is entering our equipement depending where you are on this planet and that is all we want to enter our equipment.  Anything above those frequencies can only contaminate the sound of the equipment being powered.  Let's take a closer look.
 3Khz                                           10Khz                 20Khz
A closer look reveals the average impedance around 0.470ohms. There is also a small rise that deviates and adds more impedance. This is good but it just doesn't happen fast enough. This cable will let interference enter the power going in to the powered device and the result will be;
  • Thin sound
  • Lowered dynamics
  • Poor resolution
  • Gritty / hard sounding in the midrange
  • Splashy high frequencies
  • Poor focus
             1Khz                              3Khz                                 10Khz             20Khz
In this graph we can see that average impedance is around 0.150 ohms. That is 3 times less that the regular IEC cable. Notice how fast the impedance rises and that from around 2000Hz. The rise has more than doubled from 1KHZ to 20KHz. This means that the noise above 1Khz will have more impedance (resistance) to deal with and will have a much harder time contaminating the equipment being powered. The audible results are just amazing!
  • Lowered noise floor
  • Less grunge in the higher registers
  • Better spacial resolution
  • Livelier dynamics
  • Smoother sound 
  • Depth and better stereo separation

Picture
This cable (red) is even more restrictive to good sound (3x18AWG regular IEC cord). Yellow is 2x12AWG and 1x12AWG ArtistCloner cord.
