Once you have the information you need, we want to make the purchase process as simple as possible. So we give you up-to three options on how to buy our products.

Find Your Local Retailer

Our preferred option is for you to visit a nearby store and buy what you need locally. Our authorised stockists are some of the finest specialist hi-fi retailers in the country, and they're equipped to give you the best after-sales and set-up advice possible - all in person. To find your local retailer, either click the 'Buy In-Store' button on your product page for exactly the right recommendation, or head to our comprehensive Where To Buy tool.

S-Line

The USB Box S is a high-quality external computer soundcard, built to hi-fi specification. It introduces your computer-based music to your traditional hi-fi set-up in a simple but effective way. There's absolutely no installation needed, and the sound is first-class.

Windows computer systems normally resample music from CD with Windows Kernel mixer, but this conversion is well known to deteriorate the end audio performance. Pro-Ject's direct streaming technology allows bit-by-bit processing of the audio file. This avoids unwanted signal alteration by by-passing the Windows kernel mixer. In order to get the most out of this functionality, a playback software like foobar 2000 is needed.

Key Features:

  • High quality D/A conversion
  • SMD technology for shortest signal paths
  • Output stage with ultra-low impedance
  • Automatic detection without the need of additional software, when used with conventional computer systems
  • Powered via USB
  • Runs on Windows® and MacOS® operating systems
  • Metal case shields the electronics from vibration and electromagnetic interference
  • High quality analogue output stage
  • Gold plated RCA connection sockets
