The EVO3 Sigmas is an innovative component with a power cleaning and distribution system measuring 445mm in width, 305mm deep and 90mm high. It is a significant step up from the Aquarius. Sigmas is six power cleaners in one box, and 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.
There are two high current low impedance outlets, rated at 16A, delivering 3’680W at 230V or 1’840W at 115V. These are suitable for power amplifiers, active loudspeakers, or subwoofers and feature a light version of the Titan’s Direct Coupled© circuit. The four remaining medium current outputs rated at 10A are designed for source components. These feature IsoTek’s unique Adaptive Gating © technology that auto senses the connected load, thus giving the ideal optimal clean power based upon power draw. The power cleaning network is more sophisticated than that of Aquarius.
KERP © (Kirchhoff’s Equal Resistance Path) ensures equal resistance and equal power delivery to all outlets. The internal wiring is of the highest standard; ultra-pure Ohno Continuous Cast copper solid core conductor strands with silver-plating offering low resistance and high amperage. A Fluorinated Ethylene Propylene (FEP) helix is wound around the conductor before an extruded FEP dielectric protects the conductor and creates a Virtual Dielectric of Air dielectric (FDA). This construction gives unrivaled performance and gives the ultimate low-resistance, high-performance internal power delivery system. Furthermore, 108’000A of instantaneous protection is provided, safeguarding valuable equipment via IsoTek’s unique sequential and repeatable protection system.
Sigmas is a high-quality design yet highly functional and an excellent upgrade for a complete high-end audio system improving sound stage, three-dimensional imaging, bass articulation, control, and a sense of extended frequency range and openness. IsoTek’s award-winning Premier power cable is also included.
The internal wiring of IsoTek products synergizes with the range of IsoTek power cables. One critical but overlooked area is maintaining the commonality of design and material properties through an audio wiring loom, be it signal-carrying cables or your power cable network.
