Product Description

Pro-Ject DAC Box DS is an excellent DAC for use with your computer or other traditional digital sources like your CD player and features optical, coaxial and USB inputs, available in black or silver.

Box Design

Part of Pro-Ject's "Design Series" of box components, this is a stylish, high-performance DAC which owing to its miniature size, fits as perfectly on a desktop as it would on a hi-fi stand. This is a particularly good choice for listening through USB for a number of key reasons. 

There are many ways to transmit data to and from your PC, but one of the biggest issues faced involves risking the data being overlapped by computer-based distortion and 'jitter' on the digital signal.

USB Streaming

These negative effects can negatively impact on the sound performance in the form of incorrect signal timing. To isolate and resolve this problem, the new DAC Box DS contains Pro-Ject Box Design's own asynchronous USB streaming technology. Through this method, the DAC Box DS 'cleans up' and 're-locks' the signal into its correct timing before it is converted.

Finest DAC

USB Audio supports 24-bit/192kHz HD music data in fully asynchronous mode. The DAC Box utilises the finest DAC chips available, the Burr-Brown PCM 1792 by Texas Instruments, which is usually only associated with far more expensive, high-end designs.

For the engaged audiophile, the DAC Box DS also provides two different filter settings ('Steep' & 'Optimum Phase') for selection of your favourite sound preference. The big display also shows the selected input, incoming bit depth and sampling frequency, as well as the filter settings.


The whole audio circuitry design is ultra-linear and incorporates only the finest components available at the cost, with low output impedance to avoid any negative interference or colouration with cables or pre-amps.

Key Features

- Top grade PCM-1792 D/A converter from Texas Instruments
- Capable of 24bit/192kHz asynchronous USB streaming
- Display readout shows incoming bit depth and other info
- 2 selectable filter settings (steep and optimum phase)
- Linear circuitry, extremely low impedance output stage
- Gold-plated RCA line level output sockets

Press Reviews

  • Displays are still relatively unusual in the world of DACs, especially around this price, so it’s a bit of a bonus that the DAC Box DS has one.  Of course, we’re more concerned with what we hear than what we see, and what we hear from the DAC Box DS is very nice. It’s a smooth, flowing presentation with a very even tonal balance – from deep, weighty bass to clean and clear treble. (What Hi-Fi Magazine)
