Unrivalled Performance

The V5 Sigmas is an innovative component with a power cleaning and distribution system measuring 445mm in width, 305mm deep and 150mm high. It is a significant step up from the Aquarius and its EVO3 predecessor featuring over 35% improved amperage due to decreased resistance within the circuit design as well as 40% increase in current handling capability. This dramatically improves performance. There is improved direct current resistance (DCR) throughout the new design, bringing performance closer to the zero Ohms ideal.

V5 Sigmas is seven power cleaners in one box, seven independent outlets, each one with its own dedicated clean power 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 V5 Sigmas is dramatically superior.

There are three high current low impedance outlets, rated at 16A, delivering 3,680W at 230v. These are suitable for all kinds of power amplifiers, active loudspeakers and subwoofers, nowadays TVs 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 unrivalled performance and gives the ultimate low resistance, high performance internal power delivery system. Furthermore, 121,500A of instantaneous protection is provided, safeguarding valuable equipment via IsoTek’s unique sequential and repeatable protection system.

V5 Sigmas is 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 synergises with the range of IsoTek power cables. One critical but overlooked area, is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or your power cable network.

V5 Sigmas also contains a System Link outlet, this is designed to connect multiple units together, maintaining a starred earth reference, and preserving the need for multiple wall outlet sockets.

very good book
Format: Paperback
I was 8 when the Union collapsed. I don’t remember much, but the years that followed were full of conspiracy theories and stories about who “razvalil Sovetskiy Soyuz.” This book tries to answer that question. You can sense from the book that the author is not happy with how everything ultimately evolved. The Soviet system was corrupt, inefficient, and ill, but probably there was a chance to cure it rather than kill it. However, I think the book is overall quite balanced and very informative and is a must read.

So very long….
Format: Paperback
Every time Yeltsin takes a nap? Paragraph. Bush mumbles something indecisive to Scowcroft? Boom—chapter! I felt like I was experiencing the fall of the Soviet Union in real, agonizing time. Look, it’s a fine book. If you’re going for a career in the foreign service, this is a good place to start. Otherwise, you can get a fine rendering of these events in much more concise form elsewhere.

P O W E R F U L .
Format: Paperback
The author summarized: "The ghost of the disappeared Soviet Union ... still haunts the imagination of contemporaries .... This amazing story teaches us not to trust in the seeming certainty of continuity and should help us prepare for sudden shocks in the future" (p. 439). An engrossing in-depth eloquent analyses concerning the events and individuals affecting the 1991 demise of the Soviet Union. Moreover, the unforeseen Chernobyl nuclear disaster on April 26, 1986, crystallized the horrors of a possible nuclear war. Thus, a new orientation to end the exorbitant arms race with the United States. Further, General Secretary Gorbachev promulgated new reforms, including, relaxing travel restrictions in 1989: "... [T]he shock that thousands of Soviet people experienced when they crossed Soviet borders and visited Western countries .... For first-time Soviet travelers to the West a visit to a supermarket produced the biggest effect. The contrast between half-empty, gloomy Soviet food stores and glittering Western palaces with an abundant selection of food was mind-boggling.... This experience changed Soviet travelers forever" (p. 82). At times, repetitive and somewhat confusing. For instance, U.S. President Bush needed Gorbachev's approval for his Iraq offense, which was initially described on Page 143, then inexplicably again, on Page 172. On another occasion, the author indicated that Yeltsin was influenced by Alexander Solzhenitsyn's brochure "How To Rebuild Russia," on Page 150, which is again repeated, on Page 173. Scrupulous editing needed. Notwithstanding such glitches, nonetheless, a fascinating detailed portrayal of the unexpected implosion of a superpower. Having read other books on the subject, if I had to select only ONE about the USSR collapse, I would choose this as the best.

Thought Provoking
Format: Kindle
I bought this book after I heard the author on a podcast. Growing up in the US we have been inundated with the story that the collapse of the Soviet Union was an inevitable triumph of liberal, Western values. I had my doubts. Even poorly run dictatorships can muddle along for years. What the author did was center Gorbachev in the story. He was the eye of the storm. It was the terrible combination of Gorbachev’s ambitious idealism and gross ineptitude that led to the dismantling of the Soviet Union. Unlike much of Marxist historical narratives which emphasize the forces of history; the author shows that it’s individuals who shape events and are shaped by them. A different person than Gorbachev could have turned the tide in a different direction and left us a different world than we have today. This is a history book that teaches lessons not just about the Soviet Union but about human history in general.

A compelling account of the fall of the USSR
Format: Kindle
Zubok describes blow by blow the series of decisions that sent the USSR towards disaster. Gorbachev, widely hated in Russia, comes across as principled but indecisive, ignorant of economics, and incapable of translating his worship of Lenin into coherent action. The book reads like a thriller despite the density of facts. Zubok is a pessimist, but his thesis is convincing.
