This is the AWARD-WINNING, very well reviewed DAC from ProJect that is in MINT condition but has been used just enough to be broken in.
It sounds awesome, works perfectly, looks great / like new (with no physical flaws), and is rarely (if ever) available on Audiogon. This one may go fast...

Digital micro preamplifier with MQA and DSD512 support
a performance revolution in a small package!
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!

Headfonics reviews the Pre Box S2 Digital
The Pre Box S2 Digital is one of those all-in-one solutions that defines what a typical 2018 digital audiophile might be looking for. Roon Tested, full MQA unfolding, a low noise floor, easily transportable and a very likable tonal presentation with a very modern DAC chip solution inside.

Fidelity reviews the Pre Box S2 Digital
The Pre Box S2 Digital sounds open and honest, surprisingly broadband and detailed, plays free of any attitude. The music flows just as "undigitally" and confidently as it does with a really big one.The attractive, immaculately finished chasis further reinforces the impression that Pro-Ject, has taken a major step in the development of modular audio equipment with the new S2 series.
The Pre Box S2 Digital realizes the desire for really good, modern signal processing - extremely compact and of high quality.
