S-2500 Quantum MK-II

S-4000 ProPower MK-II

S-5000 HighPower MK-II


Everything that distinguishes the StromTanks can already be found in our smallest model: a mains-independent generated perfect sine wave for the best sound. Whereby „small“ should not be considered underpowered, because the entry into the StromTank world can also be the perfect choice for many. Depending on the system configuration and listening habits, there are no limits to absolute music enjoyment with the S1000-SourcePower.

The main reason for this is the LFP batteries, and in the case of the S1000-SourcePower we are using 8 batteries (24V System). Due to their high cost, they have not been utilised in the audio sector so far, but they are extremely powerful, durable and safe. That is precisely our claim. Given the impressive dimensions of the StromTanks, it may seem almost ironic to say, but they are comparatively compact thanks to current battery sizes. Just a few years ago, the dimensions of a comparable device would have been simply absurdly large. If you prefer to listen to classical music with HiFi system that is not oversized, the S1000-SourcePower is your StromTank.

By the way: even when our StromTanks are charging, your system sounds better. You don‘t believe that? You don‘t have to, you can hear it. Connect your system to the S1000-SourcePower and give it and yourself a few days. You will no longer want to listen without a StromTank.

S-2500 Quantum MK-II

"The new middle class", if you go by our device hierarchy. Otherwise, the S-2500 Quantum MK-II is, of course, absolute top class. Here, too, we have implemented everything in line with our uncompromising approach.

S-4000 ProPower MK-II

The S-4000 ProPower not only cuts a fine figure in many recording studios. It is also a classic power tank, but one with eight LFP batteries and two inverters.

S-5000 HighPower MK-II

Many people say that life is made up of compromises. 
We say it consists of decisions. And if you have opted for a high-end system, then you also want to be able to call up its optimum performance at all times.
