Limited Edition-Luminist Power Cord

by Purist Audio Design

AC Power Conditioning Circuitry...

The circuitry features a custom magnetic control and passive multistage filtering circuits that provides impedance compensation to effectively attenuate and/or block the effects of EMI/RFI noise interference of a broad frequency range of well below 200KHz up to in excess of 1GHz. The circuit is implemented in such a way that it does not break the current carrying conductors anywhere within the bounds of the input and output connectors of the cord. This technique maintains the current capacity of the cord by minimizing overall DC resistivity, minimizes the potential for internal generated thermal noise, and maintains overall dynamics. The circuitry is protected and shielded within an attractive durable extruded aluminum housing integrated to main body of the power cord located near the power entry point.

The magnetic control circuit, which utilizes a custom configured ferromagnetic material, provides for common mode noise suppression by dynamically changing the high frequency impedance. Thus, causing high frequency noise to be either absorbed and dissipate as small quantities of heat are reflected back to the source depending on frequency and type of noise. The passive multistage filtering circuit is designed for a wide bandwidth attenuation of high frequency noise. At high frequencies the reactance of the filter approaches zero at various frequency points there by lowering the overall high frequency AC impedance, and thus shunting the presence of any high frequency noise.

Unlike purely reactive or traditional EMI/RFI filter circuits (composed mostly of inductors and capacitors), which tends to induce additional resonances within the signal path creating further noise potential, the design of the magnetic control and passive multistage filter circuit is such that it cannot. At high frequencies, the magnetic control circuit is seen as a frequency dependent resistive device and operates as a low Q series loss, non resonant element with virtually no series impedances at the very low AC frequencies. In addition, the design nature of multistage filter network is such that its reactance is inversely proportional to frequency, and at low frequencies the reactance of the filter increases without bounds. There by, it is effectively an open circuit to low frequencies. This combination in circuit topology is virtually transparent, and provides for a clean 50/60Hz power signal for source equipment.

A Letter from Jim

I’ve been in this business for over 25 years and for me, it started with art. The art of the craft, the art of music and being able to truly appreciate it as the artist intended. Our new, Luminist revision returns to these roots and is, we believe, a true marriage of art and fine engineering.


We named it for the Luminist art movement, a movement which emphasized depth and the beauty of the natural landscape and natural light. Luminist artists were so skilled that they rendered their brush strokes invisible, which kept the focus on the beauty of the painting. With our nearly 30 years’ experience, we are hoping to give you those invisible brush strokes, that you may hear music as truly, the artist intended.

Engineering, not marketing

Our Luminist revision marries engineering and art in a way they were meant to be. Constructed by hand by skilled craftsmen, and guided by nearly 30’ years experience in quality engineering, the Luminist sets a new standard in high-end audio. 


Luminist Hilights

  • Reengineered core wire to allow a more flexible design
  • Improved the metallurgy of the wire across all lines
  • New spade banana design to allow for easy change from spade or banana
  • Enhanced build quality and design for all cables
  • Enhanced Ferox and Contego Processing 
  • Improved Triple Cryomag process
  • New RCA connectors made from beryllium copper with silver then gold plating
  • New ultra-high end plugs on our top of the line AC Power cables
  • Refined engineering and enhanced design in our XLRs
  • Built by-hand, by skilled artisans
  • Engineered and built in the U.S.A


The Luminist represents quality engineering from the ground up. Our new Ferox process became Ferox 13, named because we polish it 13 times. Each polish pulls the silicon molecules closer together. It is a more efficient, spender design and requires less space to work. 


Our Luminist cables possess superior RMF, EMF, EMI noise reduction, and reduce vibration even better. It’s quality you can hear.
