Pro-Ject DAC Box RS

Full DSD Capability, Switchable Tube and Solid-State Output Stages Make Asynchronous Pro-Ject DAC Box RS an Embarrassment of Riches

Outstanding Pro-Ject DAC Box RS a Great-Sounding DAC With Phenomenal Build-Quality and Double PCM 1792 Chips

Pro-Ject's DAC Box RS is an embarrassment of riches: Switchable tube and solid-state output stages, DSD capability, versatile connectivity, fully balanced circuitry, double audiophile-grade PCM 1792 chips, fully asynchronous 24-bit/192kHz support. Comfortably handling computer audio and stereo sources, it makes music come alive with reach-out-and-touch-it detail. Phenomenal quality and top-notch options at a great price.

USB Audio Interface, DSD Support, and Asynchronous 24-bit/192kHz

DAC Box RS is a reference-class DAC for all digital stereo sound sources. It superbly acts as a superior USB audio interface for demanding computer audio and features AES/EBU input and I²S interface for use with Pro-Ject's CD Box RS. Full DSD capability (up to DSD128) over PCM is also provided. All inputs support 24-bit/192kHz HD music data (optical inputs 24/96) in fully asynchronous mode.

Exceptional Build-Quality and Audiophile-Grade DAC Chips

A pair of the best audio-grade DAC chips, PCM 1792, only found in expensive high-end designs, serve as the heart of this striking component. Two different, selectable digital filter settings will suit your favorite sound preferences, for either tubes or Solid State Class A. Ultra-low noise and ultra linear audio circuitry, with very low output impedance to avoid any negative interference with cables or preamps, rounds out the design.
