Isotek EVO3 Sigmas
Monday, February 3, 2014

Isotek’s latest whole system conditioner the EVO3 Sigmas is a six-way mains unit that combines IsoTek’s Direct-Coupled technology for power-hungry components, with the Adaptive Gating technology of the well-respected Nova, optimised for source components and preamplifiers. EVO3 Sigmas delivers a ten-fold improvement in both common mode and differential mode mains noise filtering over the original GII version.
Two Direct-Coupled outlets provide high-current low impedance filtering while “fully maintaining the transient and dynamic performance” of power amplifiers, integrated amplifiers or subwoofers. Four medium-current outlets feature a 10A capacity combined with proprietary Adaptive Gating technology which auto-senses and adapts to the current draw of the load, enabling the use of a wider range of electronic devices, from audiophile components to home cinema plasma screens, projectors and media centres. A new addition for the EVO3 version is KERP (Kirchoff’s Equal Resistance Path), this ensures equal resistance and equal power delivery to all outlets, providing a pure, coherent signal path through the unit with no interference from one socket to the next.
The EVO3 Sigmas’ internal wiring has been upgraded to IsoTek’s newly-developed UP-OCC (Ultra Pure Ohno Continuous Cast) high purity copper solid core internal wire, which is silver plated before being insulated with Teflon. A fine Teflon strand is wound helically around the wire before a secondary Teflon tube is extruded over the top, creating an air gap between wire and insulating tube and forming an air dielectric. The printed circuit board features 24-carat gold-plated 2oz copper for improved reliability and signal transfer.
EVO Sigmas 3 will be available in March for £2,295.
