The power supply is an active player in hi-fi and significantly contributes to the sound quality of a given component. Now you can upgrade both your turntable and phono preamp power supplies simultaneously and benefit from the perfect power distribution to your phono rig. Power Box RS2 Phono is compatible with all 18V Pro-Ject Phono Boxes as well as all 15V DC Pro-Ject turntables.

A linear power supply consists of a massive toroidal transformer which disallows interference from the mains to negatively impact the performance of your audio gear. The built-in transformer has a much higher power reserve compared to the standard power adapter. It has very low output impedance and in combination with a large filtration capacity, it can manage it’s task effortlessly. Expect improved soundstaging, reduced background noise, more detail & better resolution that’ll contribute to the optimal performance of your turntable AND your phono stage. Like all Pro-Ject electronics, Power Box RS2 Phono is made in Europe and available in a black or silver full-aluminum housing.
