Sbooster logo

Sbooster provides linear power supply upgrades for existing products. Sbooster greatly enhances the sound quality of your AC/DC powered hardware for devices such as music streamers and servers, D/A converters, headphone amplifiers, PC audio accessories, phono-stage preamps, routers, switches, external hard drives, etc.

Sbooster is compatible with; Lumin’s L1 and D1, M2Tech’s Young, Young DSD/DXD/PCM DAC pre-amp combo, M2Tech Marley and Joplin series 1 and Joplin MKII, and the DibiBit Aria “Mini” Server/Ripper/Renderer/Streamer.


Sbooster is an economic solution to replace a switch-mode power adapter (wall wart adapter), significantly improving sound performance with an easy to use aftermarket solution. Very suitable for products like a Squeezebox Touch, the small Tri-path T-amp may also be used for routers and switches to improve the sound of a network. Sbooster is designed and engineered in the Netherlands. The Sbooster Best of Two Worlds Solution ("BOTWS"), audio upgrade is a high-end linear power supply with the Sbooster single unit upgrade combined into one single product. This is the main focus of our Sbooster product offerings. Our recently sold out – BOTWS - audio upgrade has received a lot of positive response. This new audio upgrade product combines power, precision and efficiency in an unique innovative manner. The best choice for every audio device!

Power & Economics: The innovative electronic design of the Sbooster system is able to extract up to 50% more power out of your electronics than any conventional “wall wart,” design. The Sbooster audio upgrade is highly efficient, it only consumes a bit more energy than a stock supplied switch mode adapter.

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

Precision: Due to active and passive filtering techniques, as well as the innovative SBooster-technique, voltage and current enter in a greatly “purified” power path to your audio device. The sound is therefore free from the negative side-effects of ripple, distortion and AC/DC noise.

With the Sbooster audio upgrade, purification of the power line starts immediately when current enters the upgrade device. A dual stage mains filter and an earth line choke clean the current from high frequency pollution before the current reaches the transformer. The transformer is a custom-made audio grade transformer with electrostatic shielding. The supply is fully linear. The electronic design is innovative: it gets 50% more output of the used electronics and consumes up to 35% less energy than a conventional design. The Sbooster audio upgrade concept is so efficient that it consumes only a few dollars a year more than the standard supplied high efficient, but also highly polluting switch mode adapter. Finally, at the end of the DC cable the unique split current system has been placed. The power supply upgrade provides the split current system with powerful and clean power, so the electronics can do their job profoundly, which is to buffer the power so that the power supply becomes very fast and to filter one last time the voltage and current before they enter in to the audio device. This unique upgrade power supply with its large headroom delivers at all times, sufficient clean power to the audio device, ensuring very low noise, stable and continuous performance. This combination of power and precision results in “easy” music, a perfect soundstage, with a more natural and detailed audio experience.
