Pro-Ject Head Box S2 Digital

High power headphone amplifier with DAC - 4 outputs and 5 switchable digital filters

The Head Box S2 Digital is a full-featured headphone amplifier designed for the most demanding modern audiophile.

It supports PCM file playback and DSD decoding. It dazzles with five digital filters to tailor the resulting sound to listeners' preferences.

Three digital inputs ensure connection to any available digital source, whether it's a computer via the USB B input or a TV via the optical input. The S/PDIF coaxial input takes all data from the digital transmission unit.

The new sandwich aluminum/metal housing not only meets the highest aesthetic criteria, but also protects against vibration and interference. The Head Box S2 Digital is available in silver or black.
