Product Description

Power Conditioner

The EVO3 Sigmas is the bigger brother of our highly respected EVO3 Aquarius.  Again offering 4 medium power outlets, now rated at 10A and 2 high current 16A, driven by a light version of the Titan's Direct-Coupled© circuit. It represents an extremely cost effective full system upgrade.
IsoTek's EVO3 Sigmas represents a significant step up from our award winning Aquarius.  Sigmas features a lightversion of the Titan's high current Direct Coupled Design technology, allowing for low impedance high current delivery to two dedicated outlets.  These are specifically designed for power amplifiers, active loudspeakers or sub woofers.
A further four outlets are dedicated to all other (front end) equipment, CD player, music server, projector, pre-amplifier, etc.
Sigmas is an easy to install full system upgrade, improving a systems sound stage with increased three dimensional imaging, bass articulation and control are also improved, with a sense of extended frequency range and openness.
Housed in a striking steel and machined aluminium chassis, Sigmas is the perfect upgrade for all high quality audio systems.

"If you have a system that performs in the way you want it to and you want to try and make it better, the Sigmas delivers in spades. There are very few products that can deliver improvement across the board to a multiple unit system, but this is very definitely one of them." read the full HiFi Choice review here.
