SBooster Ultra MKII adds extra filtering and power optimization to BOTW P&P ECO supplies for streamers, DACs and sensitive audio gear. Read more.
The SBooster Ultra MKII is a premium add-on module for the BOTW P&P ECO audio upgrade power supply, created for music lovers and demanding listeners who want to refine the power delivery to sensitive audio equipment. It is designed for use with BOTW P&P ECO MKI and MKII power supplies and is especially relevant for streamers, DACs and compact digital sources. Rather than replacing the whole supply, the Ultra MKII adds an extra stage of optimization, making it a focused upgrade for systems where clarity, stability and low noise matter.
The module connects directly to the SBooster split-current module of the BOTW P&P ECO MKI or MKII, adding further filtering and power supply optimization in the final part of the chain. SBooster offers the Ultra MKII in seven versions, including 5V, 9V, 12V, 15V and 18V models, plus dedicated options for the Sonore ultraRendu and Auralic Aries Mini. Choosing the correct voltage and compatibility version is essential, so the product page and compatibility list should always be checked before installation.
In a well-matched hifi setup, the SBooster Ultra MKII can help create a quieter background, more confident dynamics and a more natural sense of space, depending on the connected equipment and the rest of the system. It is a useful upgrade for streaming setups, desktop listening systems and digital front ends where the power supply can influence overall performance. Keep connectors clean, avoid unnecessary cable strain and select the exact model for your device. Explore the Ultra MKII version that fits your BOTW P&P ECO setup.
