SBooster Ultra Upgrades

SBooster Ultra Upgrades

The Sbooster Ultra MKII is designed as an additional upgrade for SBooster's BOTW P&P ECO MKI and MKII power supplies. The Sbooster Ultra MKII has to be connected directly to the Sbooster split-current module of the BOTW P&P ECO.

New features Ultra MKII:
- The innovative electronic design filters and optimizes the input power and is fine-tuned within the audible reach.
- The Ultra MKII circuit uses upgraded input and output buffers with a higher capacity and solid conductive polymer capacitors to lower the output ripple and to expand the bandwidth of the filter circuit.
- The transient response has improved 40-50% compared to the Ultra MKI by adding new parts and lowering the output impedance to a bare minimum. The output circuit is now equipped with an impedance correction filter to achieve improved performance over a wider bandwidth.
- “Sbooster Decoy”: we all love to have our audio devices in the metal enclosures, but… also a lot of noise comes from the radiation of the used electronic components, which cannot escape from the metal enclosure and keeps on bouncing within the enclosure. How can you eliminate this noise? Via our innovative “electronic baiting container”! The “Sbooster Decoy” is integrated on the Ultra MKII to lure this unwanted noise out of the metal cage of the audio device.
- Star-ground design: the Ultra MKII is a star-ground design. Almost every component has its own dedicated ground connection. This makes the electronic design more stable and brings ease in the music.
- New designed input and output cables: the cables on the Ultra MKII have only one purpose: to pass on all the benefits of the BOTW P&P ECO and Ultra MKII design without any form of interference to the audio device. The input and output cables have high quality oxygen-free copper for the conductors and are double shielded. The interchangeable DC-connectors are equipped with custom-made gold-plated connector pins.

Ultra MKII input and output cables - extra shielded with gold plated connections

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. A must have for every audiophile!

To find out if your audio device is also suitable for the Sbooster Ultra upgrade, please check SBooster's compatibility list. You will find the compatibility list here .

NB: the Ultra is not compatible with high current demanding devices such as NUCs and NAS.

The Sbooster Ultra is based on active filter technique. The electronics of the Sbooster Ultra need power to operate. Therefore the BOTW P&P ECO power supply has to be set to a higher DC-output Voltage.

The Ultra MKII is available in 7 models. On the product pages and in the compatibility list you can discover the possible combinations:

- 5V for the BOTW P&P ECO 5-6V
- 9V for the BOTW P&P ECO 9-10V
- 12V for the BOTW P&P ECO 12-13V
- 15V for the BOTW P&P ECO 15-16V
- 18V for the BOTW P&P MKII 18-19V

- For the Sonore ultraRendu - 7.5V in combination with the BOTW P&P ECO 9-10V
- For the Auralic Mini - 15.4V in combination with the BOTW P&P ECO 15-16V

Music streamers and external HDD:
The Sbooster Ultra is designed to provide highly purified power to just one single audio device. Often external USB powered hard drives are connected to the USB port of music streamers. These USB powered devices are then powered through the USB port of the music streamer. This means, that the music streamer powers an extra device, 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.
