Unique to its class, Pre Box S2 Digital dual-mono configuration with the highest class D/A converters by Sabre. Their ESS9038 DAC chips ensure audiophile-grade sound from a compact, affordable design capable of high-resolution audio up to 32bit/768kHz PCM and DSD512. Among the first of our devices to support hardware MQA unfolding via USB, it also features our proprietary ‘optimal transients’ digital filter and our proprietary clock circuitry design. With the proprietary clock design we have managed unrivaled jitter rates of 100 Femtoseconds, easily outperforming many renowned and respected audiophile clock generators. With organic polymer capacitors and thin-film mini-MELF resistors, we were able to create a tiny device that screams value in terms of sonic performance. With a total of seven digital filters, sonics can be adjusted based on your preferences.
