Sbooster Ultra

Sbooster Ultra

The Sbooster Ultra can be used as an addition to the many filtering and optimization techniques of the BOTW P&P ECO audio upgrade PSU. The Sbooster Ultra has to be connected directly to the Sbooster split-current module of the BOTW P&P ECO.


The Sbooster Ultra is based on active filter technique, which reduces the ripple & noise of the BOTW P&P ECO even further: to a negligible low level. A must have for every audiophile!


The Sbooster Ultra is designed for audio equipment that is sensitive to residual noise, such as digital to analog converters, music streamers, USB to SPDIF converters, headphone-, pre- and phono amplifiers. To find out if your audio device is also suitable for the Sbooster Ultra upgrade, please check our compatibility list. You will find the compatibility list in the overview pages of the BOTW P&P ECO voltages.

The electronics of the Sbooster Ultra needs power to operate. This is also why the BOTW P & P ECO has more than one output setting.

Besides the active filter function, the Sbooster Ultra also re-stabilizes the output voltage to the correct voltage. Because of the short output cable of the Sbooster Ultra, the highly purified powered is lossless passed to your audio device.


Music streamers

The Sbooster Ultra is designed to provide highly purified power to just one single audio device. Often USB powerd DACs or external USB powered hard drives are connected to the USB port of music streamers. These USB powered devices are powered through the USB port of the music streamer. This means that more power is required from the BOTW P&P ECO and thus the Sbooster Ultra has to purify more power. This extra load can exceed the maximum capacity of Sbooster Ultra. In that case, the combination - unfortunately - is not suitable for the additional Sbooster Ultra upgrade.

At this moment the Sbooster Ultra is only available for the Squeezebox Touch and the Auralic Aries. Please check the overview below on the possibilities for the connectivity to the USB port (s). When new music streamers are available and suitable for the ultimate upgrade combination of the BOTW P&P ECO with Sbooster Ultra, we will add them to this overview.
