Pro-Ject DAC Box RS2

A PCM 1792 DAC with a switchable 6922 tube or solid-state output stage

The advanced DAC Box RS is a reference-class D/A converter for all kinds of digital stereo sound sources. All inputs fully support 24/192kHz HD music data (optical inputs 96/24) in fully asynchronous mode. An I2S connection lets you connect the Pro-Ject CD Box RS2 to create a high-end CD player. 

The DAC Box RS is based on the PCM 1792, and two different digital filter settings (steep and optimum phase) are available. Best of all, you can select between a 6922 tube output stage or a class-A solid-state one. Switch based on system of overall preference, or switch depending on the genre and recording quality. 

The circuit design is ultra-low noise and ultralinear with a very low output impedance to avoid any negative interference with cables or pre-amps. 

An outboard power supply is included.
