One of the most cost-effective upgrades you can buy for any high-quality audio system, Sigmas is a multi-award-winning six-way mains conditioner featuring two high-current outlets that use a lighter version of the IsoTek Titan Direct-Coupled circuit to provide high current, low impedance power for amplifiers, subwoofers, or active loudspeakers.

The four remaining output sockets are medium-current for source components. Each outlet of Sigmas has its own dedicated power cleaning network; thus, six power cleaners in one box! Sigmas represents an extremely cost-effective way to fully upgrade a complete high-end audio system.

EVO3 Sigmas is an innovative component with a power cleaning and distribution system measuring 445 mm in width, 305 mm deep and 90 mm high. It is a significant step up from the Aquarius. Sigmas is six power cleaners in one box, six independent outlets, each one with its own dedicated power cleaning network.

These dramatically reduce both Differential Mode and Common Mode noise. Cross contamination of connected components is also kept to a minimum due to the multiple power cleaning stages for each output socket. Most power filters join output sockets together, running each in series. This is an error as Differential Mode Noise created by your connected electronics will cross contaminate from one output socket to the next. The electrical architecture and design of Sigmas is dramatically superior.
