Sbooster Best of Two Worlds Power & Precision ECO (BOTW) Power Supplies cost £300 each and are replacements for the all too common wall-warts that seem to be de rigeur with many audio products. Dan Worth feels the power.

Sbooster are not new in understanding how important  power supplies are in any good audio setup. The “Best Of Two Worlds Power and Precision ECO Power Supply” is more than a mouthful to utter and yes it is one product, so I will be referring to the unit as BOTW. The BOTW supply is the successor to the companies previous supply which was based around a high quality switching supply that was smoothed incredibly well giving a notable improvement overall ripple to standard switching supplies – I’ve used a couple over the years, still favouring good linear supplies.

Sbooster themselves champion their new BOTW supplies as a fine balance between power, precision and efficiency. At the supply’s inlet their is a dual-stage line filter and earth choke, which eliminates any high frequency pollutants from entering the audio-grade transformer, which is precision wound and heavily shielded.
