IsoTek Sigmas Mains Conditioner 

Hi-Fi Choice Magazine. Best Mains Conditioner 2006 and 2007

Hi-Fi Choice comment that, “IsoTek’s Sigmas builds upon the company’s award-winning GII Mini Sub layout, with six output socket each with separate filtration. The integrated amp-sized component houses two 16A outputs, four 6A outputs and a special 20A mains in let socket with its own mains lead. We found the block brought about improvements in detail, precision and soundstaging. A year on and there’s still nothing to touch it... Yet.”

6 individually filtered outlets for Audio & AV installations

The IsoTek Sigmas features IsoTek's GII technology that forms the building blocks of the high-end Titan, Titan/Multi-Link, and Titan/Nova combinations. Sigmas has been developed primarily as a half-way house, effectively bridging the gap between the GII Mini Sub and Nova, as well as incorporating aspects of both Nova and Titan into a single chassis.

At the rear of the unit you will note six high quality outlets, these are individually filtered to stop components ‘talking’ to each other or corrupting the clean supply provided by the unit. This is achieved by a series of high quality filters on each of the outputs and a sophisticated ‘adaptive gating’ system which auto senses the requirement of filtering products connected to the medium current outlets need.

Outputs 1 & 2 (high current) feature the ‘direct coupled design’ concepts first introduced to the field of power conditioning with the Titan. This allows for almost unlimited transient ability, essential for higher power rated products, such as power amplifiers, integrated amplifiers, some ‘tube’ pre-amplifiers, projectors and plasma screens, etc. the remaining four being suitable for all other equipment.

Like the GII Mini Sub, Sigmas offers two high-current outlets and an additional four medium-current outlets for source components and preamp. However, unlike the GII Mini Sub or Vision, Sigmas delivers a cross-breed of technologies, borrowing the Direct Coupled Design and high-current aspects of the Titan, as well as the Adaptive Gating from the Nova.

All components used within Sigmas are of the highest grade or designed by IsoTek and manufactured to MOD / Aerospace specification and tolerance. All components are under stressed, which gives greater longevity. These high quality parts are then hand soldered (in England) onto the PCB with silver solder. The unit is also fully star earthed.

For many high-end audiophile applications, Sigmas will be an ideal solution, offering unrivalled performance and versatility for its price. For ultimate performance, of course, the Titan/Nova combination remains supreme.
