Pro-Ject Pre Box S2 Digital Phono Preamplifier
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 Pro-ject's devices to support hardware MQA unfolding via USB, it also features their proprietary ‘optimal transients’ digital filter and proprietary clock circuitry design.
With the proprietary clock design Pro-Ject has 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, they 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.
