The most universal & future-proof high end pre-amplifier, DAC, headphone amp!
Pre Box RS Digital combines all features of DAC Box RS plus a very linear pre-amplifier with both solidstate 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. A 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 micro dynamics 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 a I²S connection provided via RJ45, that is able to give jitter-free disc playback. Other unique advantages of this true highend DAC/preamplifier:
- Fully balanced double mono design with DAC chip selection
- Class-A circuitry with no negative feedback
- Tube or solid state output stage can be selected alternatively
- Separate power supply as an upgrade option for further improved sound quality.
- Headphone output for outstanding experience. Pre Box RS Digital is available in silver or black finish.
*Upgrade option: The addition of linear power supply Power Box RS uni (retail price € 399) adds even more depth and lets you hear all microscopic fine detail.
