Digital micro preamplifier with MQA and DSD512 support

A performance revolution in a small package!

Pre Box S2 Digital marks a new era for the S-series components. A dual mono configuration with the highest class D/A converters of ESS Sabre. Their flagship DAC-chip ensures the 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. Digital audio is the art of time, with a new proprietary clock design which managed jitter rates of unrivaled 100 Femtoseconds, this easily outperforms many renowned and respected audiophile clock generators!

Organic polymer capacitors and thin film miniMELF resistors makes 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!
