Pre Box RS Digital

Pro-Ject Audio Systems is proud to introduce the ultimate DAC/Pre-amp/Headphone amp!

Wien, (PresseBox) - It combines all the features of the DAC Box RS, plus a highly linear, variable preamplifier in Solid- State, Class-A or a selectable tube output stage. Additionally, it features a terrific headphone amplifier with adaptable output impedance for perfect matching to all headphones!

An analogue input allows the user also to connect a turntable to this unit. As with all RS Series components, the Pre Box RS Digital is fully-balanced, with both balanced and RCA input and output.

The I²S interface with separate master clock output makes it the perfect partner for our CD Box RS, with the lowest possible jitter connection!

Some background info on sound:

In all of our top-class digital products, like DAC Box RS (double), Stream Box RS and DAC Box DS (single), we use the TI 1792 24/192 DAC chip combined with a tube output configuration. This DAC chip is the most expensive DAC on the market! A tube output stage, to our ears, is by far the most musical, 'analogue'-like sound available from a digital source. Both the DAC and the tube output section represent a high investment for us, while providing exceptional value for the customer.

Because some listeners do not like tube-smoothness, we added a second output stage in Pure Class-A to provide sound with the impression of more speed!

In the same manner, we also want to get eliminate concerns about 32bit/384kHz DACs. Although there is NO COMMERCIALLY-AVAILABLE MUSIC in this format, the public is screaming about this future ca-pability. So we looked into some of these ultra-high-resolution DACs and realised that in musical terms, nothing comes close to the TI 1792. Most DAC chips sound too forward, with extremely high resolution but less fluidity as the TI 1792. We found a unique solution: to get the best of both worlds, the Pre Box RS Digital exclusively provides BOTH DAC OPTIONS on board, free for selection to meet individual tastes!


The addition of the linear power supply "Power Box RS uni" (retail price €399) adds even more depth and lets the listener hear all the microscopically fine details.

With all these sound options, allied to all the inputs, the Pre Box RS Digital represents the most genuinely 'universal' and future-proof digital Preamp/DAC/Headphone amp on the world market!

The Pre Box RS Digital is now shipping in silver and black.

BOX DESIGN regards itself as the 'next generation of hi- fi' the link between the micro-sized hardware of the IT world and the big boxes of the audiophile world. All products, except for speakers and headphones, are designed and produced in Europe.
