Sbooster BOTW AC High-Quality Power Supply Upgrade

A plug-and-play AC power upgrade for select turntables and phonostages. Drop noise, dramatically increase detail retrieval

Note: This product may not be compatible with your device. Please check compatibility first. Sbooster 2025 Compatibility List. Ensure that you are using this with an AC (alternating current) product! Unless you are sure you need AC, you might be looking for the DC Sbooster, here. 

The Sbooster BOTW AC is a direct replacement for stock AC wall adapters used in many high-performance audio components. Designed for audiophiles who want to eliminate power-related distortion, this linear power supply delivers ultra-low-noise AC current with no internal modifications required to your gear.

The BOTW AC follows Sbooster’s “Best of Two Worlds” engineering philosophy, combining robust output regulation with low electromagnetic emissions. With strong voltage headroom and a purely linear design, the BOTW AC avoids the noise and instability associated with standard switch-mode adapters.

This AC version of the hugely popular Sbooster BOTW P&P Eco is designed as an upgrade for AC-powered audio devices such as the Benz Micro PP1 phonostage, or Rega turntables with an external PSU. AC power is purified before it even reaches the transformer, which is well-shielded to use near turntables.

To make the BOTW AC power supply perfectly suited to turntable applications where the signal is extremely small and sensitive to distortion, Sbooster has added an electrostatic and high-frequency magnetic shielding to the transformer as well. An anti-oscillation circuit with WIMA capacitors ensures a stable operation of the BOTW AC power supply regardless the type of AC powered audio device. A custom-made 16 AWG shielded output cable with gold-plated connector pins ensures a low-loss distribution of the purified AC power to your device.

The Upscale View

Sbooster is one of our favorite products because it brings so much sonic benefit for the price, and is versatile and inexpensive enough for you to experience the cumulative effects of switching out all those noisy power supplies in your system. Sbooster is already our top DC power upgrade, and this AC version brings clean Sbooster power to a new set of products. Notably, it fits a range of Rega products, from the P1 up to the P8, and the Neo PSU and Fono. Some Thorens tables also work with the 16 V version. Please check the Sbooster list for compatibility.
