We will not dwell on the importance of the power supply to the audio elements and the influence of the sound. To improve the sonic performance of their products, Pro-Ject have developed a high-end universal power supply: The POWER BOX DS SOURCES. As the name suggests, it is designed for the manufacturer's sources like phono preamplifiers, CD Box, Head Box and turntables…
It comes in a large box with an elegant natural or black aluminium front panel… It includes an ON/OFF switch associated with the traditional blue LED! The rear panel features several outputs associated with the various leads (included): Two 9V outputs for 1.8 mm connectors, three 18V outputs for 2.5 mm connectors and a 15V for 2.5 mm connectors specifically designed for turntables. There is also a trigger output in 3.5 mm jack format.
Pro-Ject's Power Box DS Sources delivers a very clean and stable direct current (DC). The internal design relies on a large toroidal transformer with a copper foil shielding between primary and secondary winding. It acts as an isolation transformer that prevents interference from affecting the secondary winding, hence the circuitry and audio elements. The power of the transformer combined with a low impedance and high filtration capacity (10 000 µF) also contribute to delivering a good quality and clean current. Secondary voltages undergo very precise regulation. Also, the system is powered up and the outputs are powered via a progressive sequence that prevents a surge in the primary winding.
The addition of such a power supply to a Tube Box S phono preamp and Tube Box DS is immediately perceptible. The dynamics and definition clearly go up a notch! The brand's analogue sources and CD players alike boast a low noise level.
Recommended for owners of at least two Pro-Ject systems, like a Tube Box DS, DS 2 with a Pro-Ject 2xperience, 9xtension turntable, etc.
NB: You will need to check the product details to make sure that your system is compatible with Pro-Ject's POWER BOX DS SOURCE.
