Product Description



Pre Box RS Digital combines all features of DAC Box RS plus a very linear pre-amplifier with both solid-state and tube output stages, that can be selected alternatively. As in all our top-class digital products, we use PCM1792 DAC chips from Texas Instruments, but here we use 2 pieces in a dual differential mode to achieve ultimate fidelity. As a selectable feature, a second DAC chip from Texas Instruments is on board, that can handle 32bit/384kHz. High-class headphone output with selectable impedance for a perfect match to your headphones is also provided. Pre Box Digital RS offers 3-dimensional sound-staging, perfect microdynamics, and ultimate resolution combined with flexibility to use a wide range of digital and 1 analogue sound sources. Perfectly combined with Pro-Ject CD Box RS disc drive, Pre Box RS Digital will give outstanding sound experience, because of an I²S connection provided via RJ45, that is able to give jitter-free disc playback.
