The new Pre Box S2 Digital ultra-compact stereo preamplifier is a product that offers high-class technical solutions at an unequivocally democratic price. Defined by its creators as a “premium” digital preamplifier with double monophonic circuit topology and three digital inputs, the Pre Box S2 Digital is not “just another product” from Pro-Ject , but a true milestone among the achievements of its category as a consequence of its unique conception. This is corroborated first of all by a D/A conversion section that, thanks to the use of two D/A converters from the elite SABER range from ESS Technology, allows you to obtain a sound that is as warm and captivating as it is clean, transparent and brimming with information.

Specifically, the SABER ESS9038Q2M D/A converter is a very high-performance device with 32-bit technology that incorporates the Hyperstream architecture and the Time Domain Jitter Elimination circuit, both exclusive technologies from ESS Technology. The Pre Box S2 Digital is also the first Pro-Ject product to support hardware for the MQA (“Master Quality Authenticated”) encoding scheme, which promises a superior sound experience from smaller file sizes and therefore much more. easy to stream or download. As a state-of-the-art digital component, the Pre Box S2 Digital is prepared to reproduce the most demanding “hi-res” of the moment, while incorporating very high quality digital and analog components and a completely metal and anti-resonant enclosure.
