The Sbooster Single Unit, the "Best of Two Worlds Solution" audio upgrade power supply and the new "Best of Two Worlds Power & Precision ECO" audio upgrade power supply and all our other audio upgrade products are designed and developed in the Netherlands.

In 2008, Wiebren Draaijer, founder of Sbooster / Squeeze-upgrade, received a Logitech Squeezebox as a gift. Soon he noticed the convenience of streaming audio, but it an audiophile his was totally dissatisfied with the sound quality of the Squeezebox compared to his high-end CD-player. With his background in electronics tried the find a solution that would improve the performance of the Squeezebox. It soon became clear that the standard supplied switch-mode adapter was the one that had a negative impact on the performance of the Squeezebox. The question was how to solve this problem? The Sbooster Single Unit was born. The “current improver” for almost all standard switch-mode adapters of small devices.

In 2009 Sbooster Single Unit is further developed and made production ready. Meanwhile, the Sbooster-technique was combined with the best elements of a linear power supply. The result: the Best of Two Worlds Solution audio upgrade power supply (BOTWS).

At the beginning of the product development some audio enthusiastics. They listened very to our products over and over again and provided us with information to improve our prototypes. We are very grateful to them!

Due to the many requests outside Europe for our products and because of new high-res audio, like DSD and the DSD-DACs we started to develop the successor of the BOTWS audio upgrade at the end of 2013. We proudly present: the "Best of Two Worlds Power & Precision ECO" (BOTW P&P ECO) audio upgrade. At the development of this product we had the following goals in mind:

  • Worldwide use with an equal perfomance at every mains voltage;
  • Energy savingd, higher efficiency and more power;
  • Achieve an even greater improvement in sound by getting the most out of your audio device.

In our opinion we have achieved our goals! This new audio upgrade power supply combines power, precision and efficiency in an innovative manner. Through smart design this upgrade product performs the same at any mains voltage. 

The innovative electronic design is able to extract up to 50% more power out of the used electronics than any conventional design. The BOTW P&P ECO audio upgrade concept is highly efficient, it only consumes a couple of dimes more energy than the stock supplied switch mode adapter.

The unique split-current system ensures that the audio device, to which the BOTW P&P ECO audio upgrade is connected, has an unlimited source of pure energy. The audio device will perform at its best.
