For the very first time it is using a dual mono configuration with the highest class D\/A converters of ESS Sabre. The 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 Pro-Ject's proprietary Optimum transient digital filter and its proprietary clock circuitry design. Digital audio is the art of time, with Pro-Ject's new proprietary clock design it has managed jitter rates of unrivaled 100 Femtoseconds, this easily outperforms many renowned and respected audiophile clock generators!\u003c\/p\u003e\n\u003cdiv class=\"textual \"\u003e\n\u003cp\u003eWith 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.
