Product Description

Pro-Ject Power Box RS Uni 1-Way is a specially developed linear power supply for your Box Design RS Hi-Fi component. Designed to significantly enhance the sound quality by improving the audio path.

This high-end power supply upgrade is compatible with the following RS components: CD Box RS, DAC Box RS, Head Box RS, Pre Box RS, Pre Box RS Digital and Stream Box RS.

Audio Components

The Power Box RS consists of a massive toroidal transformer with shielding between the primary and secondary winding, which acts as an isolating transformer and avoids penetration of interferences from mains power into the audio component. 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 large filtration capability it can easily manage all power needs. 

By upgrading your RS components power supply with the Power Box RS you can benefit from greater and improved sound staging and detailed resolution which all contributes to a far better overall performance from your system. The Power Box RS Uni 1-Way is able to accommodate a RS components and comes in Black or Silver.

- Audio type toroidal transformer and low ESR capacitors 
- Main isolating transformer with copper foil shielding 
- Secondary voltage rectification with precise regulation 
- High filtration capacity (10.000 µF for each output)

    I have had a Pre Box RS Digital for several years and only now decided to stump up for a linear power supply.
    Honestly - night and day is the best way of looking at this. Whilst £359 seems, on the face of it, steep for a power supply, the simple truth is that Pro-Ject Audio really shouldn't let you buy any of their stuff without a linear power supply.
    Everything is improved. In particular, violin strings are smoother and their potential to fragment is almost gone. Bass is tighter, detail is improved and, to summarise, the whole becomes significantly more musical, has greater weight and is more pleasurable.
    Best £300+ I have ever spent on audio equipment. Moral of story - don't try to build a house on unstable foundations. Clean power matters!!!
