High end preamp, D / A converter, headphone amplifier Universal & future-proof: high-end preamplifier, D / A converter, headphone amplifier! The Pre Box RS Digital combines all the features of the DAC Box RS with a highly linear preamplifier, which has a switchable output stage in transistor and tube technology. As with all of our top-of-the-line digital products, we use the PCM1792 DACs, which are used twice in dual differential mode for ultimate fidelity. As a unique feature can alternatively be switched to a 32bit / 384kHz converter chip also from Texas Instruments. The also available high-quality headphone amplifier has a switchable output impedance to allow optimal adaptation to any headphone. The Pre Box Digital RS offers 3-dimensional room image, Perfect fine dynamic playback and ultimate resolution with the ability to connect a variety of digital and analog sources. Especially in combination with the Pro-Ject CD Box RS drive, the Pre Box RS Digital can show its qualities, as a specially suitable I²S interface (via RJ45) ensures maximum jitter-free reproduction.
