It marks a new era for Pro-Ject's S-series, using — for the very first time — a dual-mono configuration built around ESS Sabre's flagship D\/A converter, for highest-class audio in a compact, affordable form.\u003c\/p\u003e\n\n\u003ch3\u003eReference ESS Sabre Dual-Mono DAC\u003c\/h3\u003e\n\u003cp\u003eTwo ESS9038Q2M 32-bit DAC chips run in dual-mono for exceptional resolution, handling high-resolution audio up to 32-bit\/768kHz PCM and DSD512. It is also Pro-Ject's first device to support hardware MQA unfolding, and it debuts the proprietary Optimum transient digital filter and Pro-Ject's proprietary clock circuitry.\u003c\/p\u003e\n\n\u003ch3\u003eClock Design \u0026amp; Premium Components\u003c\/h3\u003e\n\u003cp\u003eDigital audio is the art of time: Pro-Ject's proprietary clock design achieves jitter as low as 100 femtoseconds, easily outperforming many renowned audiophile clock generators. Organic polymer capacitors, thin-film miniMELF resistors and a gold-plated four-layer PCB let this tiny device outclass far larger, more expensive components.\u003c\/p\u003e\n\n\u003ch3\u003eSelectable Digital Filters\u003c\/h3\u003e\n\u003cp\u003eMultiple selectable digital filter characteristics — plus Pro-Ject's proprietary Optimum transient filter — let you precisely shape the sound to your taste.
