Pro-Ject Pre Box S2 Digital Edition 23 - Pre-Amplifier
The Pro-Ject Pre Box S2 Digital – since its release back in 2017 – has quickly ascended to an exceptional status in the DAC market and gained a reputation among digital and PC-audio enthusiasts for its remarkable ability to compete way above its price point. The 2023 Edition, following the chip crisis of 2020/21 saw a rework and upgrade to several components, making the Pre Box S2 Digital 2023 Edition even better than ever before.
Edition 23 Improvements
New Internal Power Supply Design
The power supply units (PSUs) of clock, DACs, and analogue output stages have undergone enhancements to offer increased isolation from PC USB power noise and achieve a wider/flatter output impedance across the entire audio bandwidth.
Redesigned Master Audio Clocks
Pro-Ject have redesigned and improved the discrete audio master clocks – this lowers the phase noise and further enhances the already cutting-edge jitter performance.
New Output Stage with Higher Class-A Current
The new analogue output stage, based around the SABRE9603Q, has higher Class A operating current, for improved performance with low impedance headphones and long cable runs.
New Headphone Amplifier
The entire design is now more energy efficient – a 12% reduction in PSU current, while also offering higher Class A analogue stage operating current resulting in lower distortion when used with low impedance headphones. Users with mobile devices or laptops on-the-go will also appreciate the lower power draw, and simultaneously enjoy more power for the energy that is being drawn. And for anyone finding themselves using low-impedance headphones or in-ears – whether in a mobile, home, or work environment: they will experience a noteable boost in sound quality too.
