Pro-Ject Stereo Box DS2 Integrated Amplifier

The Stereo Box DS2 is a high-power stereo integrated amplifier in the traditional style, but featuring modern conveniences and Pro-Ject‘s popular small footprint structure.

Designed to focus on two of the most common sources requested today, the Stereo Box DS2 features both a built-in phono stage and a built-in Bluetooth receiver. The phono stage draws from Pro-Ject's extensive experience with turntables and offers options for both Moving Magnet (MM) and Moving Coil (MC) cartridges. The Bluetooth input provides modern convenience, allowing for quick and easy pairing to smart devices for instantaneous high-quality music reproduction. There are also three additional RCA line inputs for adding other sources such as DACs, CD players or music streamers. 

The Stereo Box DS2 features a dual-mono amplifier design principle, making it able to drive a huge range of speakers with ease. Such is the sophistication of the internal design, the amplifier will make any attached speakers come to life with powerful transients and a rich, wide and dynamic soundstage. For wider system integration, the Stereo Box DS2 also features fixed and variable RCA outputs (for active speakers or a subwoofer). For times when you need to keep quiet, there's also a 6.3mm headphone jack on the front panel that's driven by its own dedicated amplifier stage and has ample headroom to drive the best sounding headphones.

No corners were cut when designing the Stereo Box DS2. Though it's simple and convenient in its layout, and small enough to fit into any hi-fi system, the heart of the product still remains with its sound quality - and there it comfortably competes with much bigger designs. 

Like all other DS2 products, the Stereo Box DS2 is available in a variety of finishes, including with or without retro styled wooden side panels (read our FAQ for more information).
