Pro-Ject Power Box S3 Phono Power Supply

Power Box S3 Phono is a very efficient and flexible power filter for your turntable and phono preamp. By placing the power supply outside of the main component, potential noise and audio signal contamination is avoided. Clean energy contributes significantly to the sound quality. 

The Power Box S3 Phono's two outputs are specifically engineered to power Pro-Ject turntables and phono preamps. The sophisticated DC filtration can have a dramatic impact on the sound quality. In addition to the sound improvements, Power Box S3 Phono also offers its users a cleaner cable soluti- on avoiding PSU and cable mess.

The new Power Box Phono S3 is carefully designed and handmade in Europe. We aim to develop a technically flawless device in a housing that is only as big as necessary to save raw materials. Due to the timeless design & rigid aluminium casework, the Power Box Phono S3 is built for eternity.

With high-quality materials and components and well-thought-out design, we want to pioneer the industry.
