30th Anniversary Power Cord

To further commemorate 30 years of crafting detailed and musical cables, Purist Audio Design is pleased to release the 30th Anniversary Power Cord! We took everything we learned from our stunning 25th Anniversary Power Cord and dialed it up to 11! The 30th Anniversary is comprised of a custom wire bundle with 8 AWG finely stranded SCS (single Crystal Silver) conductors, Contego for improved shielding and dampening, improved AC power conditioning circuitry, and terminated with the Furutech’s NCF (Nano Crystal2 Formula) connectors! This cable is specifically built for the most demanding, most detailed, and most revealing systems.

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.

The Connectors

“Furutech’s Pure Transmission FI-50 NCF Piezo Ceramic series connector bodies and housings feature several breakthrough construction techniques. A multilayer nonmagnetic stainless steel and silver plated carbon fiber shell incorporates a special damping and insulating acetal copolymer. Furutech settled on stainless and silver plated carbon fiber for the outer housing after extensive listening sessions with Japanese industry figures and audiophiles. The body of the connectors incorporates an “active” damping material: Nano Crystal² Formula - Nano Crystalline, Ceramic and Carbon Powder Incorporated into select Furutech products, Nano Crystal² Formula --- NCF is comprised of a special crystalline material that has two “active” properties. First, it generates negative ions that eliminate static and secondly, it converts thermal energy into far-infrared. Furutech then combines this remarkable crystalline material with nano-sized ceramic particles and carbon powder for their additional “Piezo Effect” damping properties. The resulting Nano Crystal² Formula is the ultimate electrical and mechanical damping material – only found in Furutech products! Nano Crystal² Formula eliminates static, “interconverts” thermal, mechanical and electrical energy and damps vibrations."
