Pro-Ject Amp Box DS2

Digital power amplifier with 2 x 100 W at 8 Ω and high efficiency up to 92%

Audiophile-grade, very warm to tube sound with substantial volume, clear surround and pleasing detail.

The amplifier's power is sufficient to power even demanding loudspeakers, and the distortion exhibits very low values across the entire frequency range without depending on the current load.Thanks to its low output impedance and minimal noise, the Amp Box DS2 meets the highest sonic standards for spatiality and microdynamics.

The four-layer circuit board allows the shortest possible signal paths to be used, thus guaranteeing high sound quality despite its compact size.The Amp Box DS2 delights listeners with a fresh, energetic and smooth sound that can only be heard in much more expensive components.

The Amp Box DS2 power amplifier finds its application in many home applications where superior sound, small size and high performance are required.As an additional upgrade, you can use the Power Box DS2 Amp for separate power supply to further optimize sound quality.

The sandwich chassis made of aluminium and metal is not only highly aesthetic and robust, but also protects the amplifier from vibration and electromagnetic interference.Silver or black finishes are available, and alternatively, an elegant optional extra can be selected, complete with wooden side panels made of walnut or eucalyptus wood.
