Dual-Mono Pro-Ject Pre Box RS2 Digital Preamplifier/DAC Decodes 32-Bit/768kHz PCM, DSD512, and MQA: Features Dual ESS SABRE DACs, Switchable Analog Output Stage

The larger, deluxe edition of the award-winning Pre Box S2 Digital, the ultra-linear and EISA Award-winning ProJect Pre Box RS2 Digital preamplifier/DAC touts the same superb DAC chipset while adding even more technology – including a switchable analog output stage that lets you choose between solid state and tube. Eight digital filters as well as nine digital inputs, separate signal paths for the left and right channels, optional selectable upsampling of PCM and MQA, advanced re-clocking of the USB input by an XMOS chip with multi-core RISC architecture, and an aluminum remote control further place the European-built Pre Box RS2 Digital at the top of the European company's value-addled S2 Series.

Featuring dual-mono construction and dual ESS Sabre 9038 chips, the 3.8-pound unit brings high-end digital decoding and immersive audiophile fidelity to your space for a stunningly modest price. Able to support up to high-resolution 32-bit/768kHz PCM and DSD512 via USB, Pre Box RS2 comes equipped with Pro-Ject's proprietary Optimum transient digital filter straight from the creators of MQA. Plus, RS2's passively filtered USB output drops the noise floor to near-inaudible levels. Organic polymer capacitors, thin film mini MELF resistors, a gold-plated four-layer PCB, and vibration-resistant metal housing further contribute to its mesmerizing sound.

Want to listen through ‘phones? Free of any coupling capacitors, the built-in headphone amplifier claims a fast DC servo and delivers stellar output power to match with a wide variety of headphones. Want more options? You can also enjoy MQA by linking Pre Box RS2 Digital with Pro-Ject's CD Box RS2 T, which can be connected to RS2 by reliable I²S differential bus via the HDMI connector whereby Pre Box RS2 Digital also provides the master clock (16.9344 MHz). A large display screen, easy-to-operate menu, and a pair of XLR inputs help complete a miniature marvel made to please. 100% Music Direct Guaranteed.

"Digital connections to the hugely flexible Pre Box RS2 Digital DAC even include HDMI, with a synchronizing clock. The latter also boasts Bluetooth, USB-B, coaxial and Toslink digital inputs, with a choice of solid-state and tube-based analog outputs."
