A performance revolution in a small package!
Designed by hi-fi veteran John Westlake, the Pre Box S2 Digital is a powerhouse that’s ready to handle the newest and highest-resolution digital files with grace and precision.
The most affordable MQA DAC on the market
Featuring a high-resolution ESS Sabre ESS9038 DAC and hardware MQA unfolding a feature commonly found on much more expensive DACs, the Pro-Ject Pre Box S2 Digital packs a top-of-the-line audio experience into a palm-sized product, all for a stunningly approachable price.
Pre Box S2 Digital marks a new era for our S-series components. For the very first time we are using a dual mono configuration with the highest class D/A converters of ESS Sabre. Their flagship DAC-chip ensures highest class audio in a small and affordable package. This DAC is capable of high resolution audio up to 32bit/768kHz PCM and DSD512!
Pre Box S2 Digital is also the very first of our devices to support hardware MQA unfolding. It’s also the premiere of our proprietary Optimum transient digital filter and our proprietary clock circuitry design. Digital audio is the art of time, with our new proprietary clock design we have managed jitter rates of unrivalled 100 Femtoseconds, this easily outperforms many renowned and respected audiophile clock generators!
With organic polymer capacitors and thin film miniMELF resistors we were able to create a tiny device that will blow away even much bigger components for a much higher price. With a total of eight digital filters the sound can be shaped precisely to the listeners liking. Pre Box S2 Digital is fully remoteable, it can also control the playback software of a computer. You can use Play, Pause, Forward and Rewind straight with your Pre Box S2 Digital!
Award winning design
"This petite box shows that – in the world of digital audio – less can be more. Its long list of features includes full preamp functionality and the latest ESS Sabre DACs running in dual mono configuration. So it handles everything from DSD512 to 768kHz/32-bit PCM music media and will even recognise and decode MQA files. High quality passive components, an integrated headphone amplifier and a host of digital filter options complete the big picture. With an open and expressive nature, and supreme versatility, the Pre Box S2 Digital sounds bigger and bolder than it looks – making it great affordable hi-fi."

Pro-Ject Audio has been reviving music since 1990. After the fall of the Berlin Wall, when factories were closing in droves, founder Heinz Lichtenegger bought a turntable factory in the small Czech town of Litovel. Retaining the experienced staff and re-imagining classic turntable designs, we went to work constructing low cost, design-oriented turntables that would help people rediscover music the way it should be.
We're still working with the same staff out of the same small factory in Litovel. We've kept revising our low cost options for the easiest use, best sound and cleanest finish. But we also build midrange and high end turntables... and a whole lot more.
We don't expect you to believe everything we say. You've got no reason to trust us, so don't. Look up reviews and ask your friends. We're talked about and reviewed positively, and for good reason. Whether you're after a cheap and easy 'table, a high end award winner or quality hi-fi equipment, you'll keep coming across one name. That's Pro-Ject Audio Systems.
