The invention of purest sound quality
Made in Germany

In current social theory there is the common term “pyramid of needs”.

If one simplifies it to two statements, it says that we all primarily need immediate things in life such as food and sleep, and only then we develop needs for cultural enrichment.

If this rather wise scheme is applied to current technological change, it becomes clear that in modern society everybody needs electrical energy at practically all stages of his or her immediate needs. With electric energy we prepare and preserve food, move about and communicate with friends, conduct professional negotiations, have fun and realize ou creative spirit – even when electric energy only burns as a lamp above the desk.

But have we ever thought about energy quality?

If you ask a driver what gas quality he will use for any car he will definitely choose clean, recommended gasoline with a high octane rating.

Electrical energy, however, is a matter that is more difficult to judge. We are faced with a multitude of daily routine equipment that surround us but that hardly react to a wide variety of network fluctuations – they react only to radical voltage spikes and power black outs.

The qualitative character of electrical energy is most evident where it is directly converted into mechanical energy, if it is in a clean signal accessible to our perceptive organs or in light/color and sound.

One of the most important facts to hear the excellent quality of your audio-components is the purity and stability of the grid signal.

Until electrical energy reaches your system it has travel hundreds of meters from the generating station. There is certainly no high-quality power cable on this route, so the energy will encounter a whole kaleidoscope of interferences on its way – from a multitude of radio signals to the feedback of thoudands of electrical devices connected to the electrical grid.

Daily routine equipment like PC’s or microwave influence the grid. Everyone is connected to the same dirty grid polluted with DC voltage, high level and frequencies.

Electric current entering your amplifiers is therfore about as clean as water in a small forest pond. It looks okay most of the time and does not cause any direct damage, but is interspersed with a host of microscopically small life forms. Hence it is clear that fluctuations in power quality have a detrimental effect on the capabilities of the connected components.

They simply do ot receive enough “good” (clean) current to develop their full potential.

Audiophiles are waiting until deep in the night for a less-disturbed AC-grid to get good sound.

Dreams come true – with your own real GENERATOR

After extensive research on various ways to improve the quality of the network, we opted for a radically different approach.

We take care making you completely independent from the traditional, fluctuating domestic power grid, by developing your own, independent power plant to supply your audio components.

This power generator is called STROMTANK.

Only the power generator STROMTANK offers you the unique opportunity to provide your system with stable energy, completely disconnected from the electrical grid. This complete network separation works for hours, and it may be perfect for you during this time no matter how many power plants are on and off be turned off and how many hair dryers and PowerLAN adapters in the Neighborhood mischief.

So what to do bringing the whole musical material to its full sonority to unfold?

A mains filter could be used to protect the system from overloads and to smooth out particularly unpleasant bursts for sound reproduction but this does not help to maximize the flow of energy. You can go one step further and install a regenerator that improves the sinusoidal shape of the electrical signal but this leads to a loss of sound dynamics.

This topic has been known for a long time, it has been worked on in many places.

However, a consequent solution was not in sight for a long time. Until now!
Stromtank is not a traditional conditioner or a simple filter, Stromtanks create their own perfect AC waveform and when in green operating mode, are completely disconnected from the AC grid.

For years, there have been many devices that use a variety of techniques to address AC power anomalies. The Stromtank models take this a step further and instead of simply adding a filter to the AC power signal, a Stromtank creates its own AC power! A Stromtank is completely independent from the traditional, fluctuating domestic power grid, by developing its own, independent power plant to supply your audio components.

Stromtank offers unique opportunity to provide audio system with stable energy, completely disconnected from the electrical grid. This complete network separation works for hours and is electrically disconnected from the AC main circuits isolating the system from any AC surges, sags, noise, or radiations.

What’s inside

The heart of all the Stromtank units is the innovative battery technology known as lithium iron phosphate (LFP). Stromtank uses a special type of LFP battery that offers maximum power delivery, extended battery life, voltage stability, and intrinsic safety. The lifetime of Stromtank batteries is ensured by a battery management system that was specially developed in conjunction with the Fraunhofer Institute in Nuremberg, Germany – experts in efficient battery management technologies.

Each individual cell provides feedback to the active battery management system. This intelligent system has three major functions:

- Active balancing of all cells in the array to maximize efficiency of discharging and charging cycles.
- Inspection of temperature, voltage, current load and state-of-charge of each single cell
- By monitoring and managing the battery array, the system is completely maintenance free

Digital Distortion Suppression
Eliminating digital and backwards interference from other audio components.
