The DAC Box DS is not only an excellent D/A converter for 'traditional' digital sound sources (such as CD players) because of its optical and coaxial inputs; but it also acts as a superior USB audio interface for the increasingly demanding world of computer audio. Moreover, the DAC Box DS is now one of the most affordable hi-fi DACs available to handle pure DSD playback. With a free update released in March 2014, the DAC Box DS can now play DSDx64 and DSDx128 DSF audio files.
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. 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.
USB Audio supports 24-bit/192kHz HD music data in fully asynchronous mode, and DSD audio over PCM (DoP) markers. The DAC Box DS therefore utilises the finest DAC chips available - the Burr-Brown PCM 1792 by Texas Instruments - devices which are 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.
Avaialble with Black or Silver faceplate.

You do not need a driver. The driver is already integrated in the operating system.
Turn off your Computer and press at start alt+cmd+p+r until another starting sound appears. With this command the USB bus will be reset and the USB Box will be recognized new.
There are many forum reports about that issue. It is a widely spread error affecting a wide array of USB DACs, unfortunately there is no current fix for this problem, since it lies in the Core Audio of Apple's OSX. We advice not to use our USB DACs with OSX El Capitan.
