Material, design and engineering - all elements vital for pure signal transfer were technically investigated to provide the ultimate in reproduction quality. ESOTERIC power cord series - Hear everything as it was meant to be through components powered with ESOTERIC's high-end power cords!
Pure conductor / Stressfree annealing technology
ESOTERIC power cords incorporate high purity "Stressfree" copper conductors. The material purity of conductors used for critical areas is 7N (99.99999%) copper. This high purity material was originally developed for the semiconductor industry which requires an extremely high level of quality certification, and guarantees 7N purity with less-than-0.01 ppm (parts per million), of metallic impurities. This quality level is maintained by using 'GD-Ms' high precision material analysis technology. The high purity copper wire uses special "Stressfree" annealing technology to minimize distortion of the crystalline structure of the copper. These new power cords also feature extra-large crystalline structure conductor technology, "D.U.C.C." (Dia Ultra Crystallized Copper) in order to farther optimize the high purity and conductivity of the power path.
Stressfree 7N (99.99999%)
The 7N-PC5500SE is a true high performer in ESOTERIC’s ultra high end power cord line. The 7N-PC5500SE shares most of the key technologies with its big brother 7N-PC7500, yet some features are simplified to provide affordability.
The cable incorporates high purity, D.U.C.C. (Dia Ultra Crystallized Copper) 7N Cu conductor produced by our Stressfree annealing technology. Polyolefin insulation provides extremely low dielectric property (1/4, compared to conventional PVC material). The cable jacket is finished in a high gloss, transparent black.
The new SE "Speciale Edizione" version features the same IEC / Wall plug used for the PC7500 and PC9500 MEXCEL. We changed plating on the beryllium copper contact elements from platinum + palladium to the highest quality siliver + rhodium plating, and the end result is a sharper focus and more precise detail.
