The Sigma uses 5 stages with additional delta filters at each end to emulate a full 9-stage design. IsoTek's current Titan design consists of a 9-stage cascaded design using natural roll-off and no Chevishev type characteristics, i.e. About the Sigma, one seller's website proclaims that it "takes the high current direct-coupled design of the Titan for the high current and combines Nova and GII MiniSub and Vision technology for the medium current components. The Titan is a dedicated two-outlet high-current affair said to render further advances when feeding the power amplifiers separately. The Sigma S is a 6-socket complete systems solution sufficient unto itself. The following tech paragraphs are culled from that draft and then Frederic takes over again. As is my habit however, I had already penned the obligatory tech section and exchanged e-mails with Isotek's Keith Martin. * In April 2008, I was solicited to do a review on the Sigma S and Titan units but never received the promised loaners. I won’t pretend to understand how either of these work to instead point you at Isotek’s website* where most of the technical information can be found - although understandably, the real particulars of their circuit implementations are not fully disclosed. The Nova is intended primarily for front-end equipment (sources and preamplifiers) while the Titan is optimized for power amplifiers with massive current draw. The Nova and Titan sit on top of Isotek’s product range. ![]() After Isotek worked through financial difficulties and rose again like a Phoenix, the Sound Organization is now in charge of US distribution. This review started with Genesis being the US distributor. In came the Nova and Titan filters by Isotek. To a less drastic but related extent, that’s what the Monster filter did on this very revealing association of gear, the most damaging effect being obtained by plugging the Genesis Hypex-based amplifier in the filter. While the ambient noise level comes down, everything sounds muffled. Yet over the past six months, my system underwent a few radical changes that were to upset this pastoral picture of tranquility.Ī dedicated quieter room treated with Frank Tchang’s resonators enabling a better perception of nuances and subtle differences a far more revealing pre/power combo with the Esoteric C03 (or now Wyred4Sound STP) and Genesis GR360 and as cherry on top, the Zu Essence capable of superb microdynamics and transient fidelity - although the quieting effect of the Monster filter was obvious in this system/room, so was the damping of dynamics and transients. It kept the AC gremlins out while staying reasonably unnoticed in its nefarious side effects. ![]() Up to now, my Monster power filter had been doing a more than commendable job for its $500 sticker. Living in a rural area where most of the disturbance to the power grid comes from the milking machine at the neighbor’s dairy farm, the benefits of deep filtration have always seemed dubious to me - until of course the month of August arrived and with it the 24/7 air conditioning with all its associated spikes and noises. In the worst case, the soul of the music goes with them. At best, I look at those devices as necessary evils that deliver a needed clean-up of the incoming power yet like the devil, always take something in return. Unlike Paul or Marja and Henk, I have a hard time getting excited about power filtration and conditioning.
