STROMTANK S-5000 HighPower MK-II 

Life consists of compromises, many say. We say it’s made up of choices. And if you have chosen a high-end system, you also want to be able to call up its optimum performance at any time. That’s why our top model, with its truly gigantic power reserves, has a very simple mission: to stand by the best systems.

Its performance data speaks for itself: 5000 Wh and 1500 VA continuous power at 25 degrees ambient temperature. Alone the DC/AC inverter we use, which is specially optimized for audio purposes, is more expensive than many end devices. The S5000-HighPower is the largest StromTank with 16 high performance LFP batteries (48 volt system). No fewer than two power inverters provide ultra-stable power delivery capability.

It does not only make sonic sense to provide the best, largest systems with such a power base as our StromTank S5000-HighPower.  The energy requirements of large power amplifiers in particular require an absolutely stable supply and they will thank you with longer operational life, as well as pure musical enjoyment.

Of course, you can also combine the S5000-HighPower with a less elaborate system and thus put off replacing components that you thought would no longer meet your needs.
The S5000-HighPower shows listeners who appreciate the best very clearly what is really in their system.

Everything that characterises the StromTanks can already be found in our smallest model. Depending on the system configuration, even with the S-1000 there are no limits to absolute music enjoyment.

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.
