The Pro-ject Pre Box RS Digital combines all the features of the DAC Box RS with a pre-amplifier with both solid-state and tube output stages. The Pre Box RS Digital uses two PCM1792 DAC chips from Texas Instruments in a dual differential mode to achieve ultimate fidelity. A selectable second DAC chip from Texas Instruments can handle 32bit/384kHz signals.

As well as stereo RCA and balanced XLR, there is also a high-class headphone output with selectable impedance for a perfect match to your headphones. The Pre Box Digital RS offers 3-dimensional sound-staging, perfect micro dynamics and ultimate resolution combined with flexibility to use a wide range of sources. With a dedicated clock output and RJ45 input for combining with the Pro-Ject CD Box RS disc drive, the Pre Box RS Digital will give outstanding jitter-free disc playback.

An excellent high-end DAC and preamplifier from Project.
