The Best of Two World Power & Precision ECO is the successor of our Best of Two Worlds Solution upgrade. For the BOTW P&P ECO we have applied a large number of innovative techniques in order to improve the sound quality of your Beresford Caiman+ to a much higher level compared to a conventional linear audio power supply.

Sbooster ultra

The Sbooster Ultra is an innovative addition to the BOTW P&P ECO in the fight against pollution. The Sbooster Ultra is based on a highly effective active filter which reduces any residual noise within the audio spectrum with > 110dB. The purity of the voltage and current of the BOTW P&P ECO with Sbooster Ultra Upgrade is the highest level that ever has been reached with an external audio upgrade power supply solution.


Like the BOTWS we have equipped the BOTW P&P ECO 15V - 16V with an interchangeable DC-tip system. In addition, the BOTW P&P ECO power supply has a selectable output voltage of 15V, 16V, and an accessory setting. This last setting can be used with Sbooster Ultra upgrade or other quirky applications of Sbooster.

Check our compatibility list for an overview of all the audio devices for which the BOTW P&P ECO 15V - 16V is suitable as an upgrade.

The BOTW P&P ECO 15V - 16V is available in a 100/110/115/120/220/230/240V AC 50/60Hz version. With your order, please select the version that meets your local mains voltage. Additionally, you can select one of the four mains cable variants. If you prefer to use a special audio grade power cord with the BOTW P&P ECO please note that the mains cable has to be equipped with an IEC 13 connector.
