High performance DAC and headphone amplifier

Pro-Ject Head Box S2 Digital comes fully equipped for the highest demands of the modern audiophile. It supports playback for PCM files up to 32bit / 768kHz and DSD decoding up to quad DSD (DSD256). Head Box S2 Digital also comes with five digital filters for soundshaping to the listeners preferences. Three digital inputs ensure to connect to any source available, be it a personal computer via the USB B input or a TV set via the optical input. The co-axial S/PDIF input takes all data from a digital transport such as the CD Box DS2 T. All inputs offer support for high resolution data up to 24bit /192kHz. The USB input offers full high resolution support for all files up to PCM 32/768 and DSD256. The front seated 6.35mm headphone output delivers a clean and precise sound with a musical touch. Un-wanted noise coming in through USB is double filtered to surpress them to a level where it can’t affect audio to realize an undisturbed listening experience. The new aluminium/metal casing ensures highest aesthetics and protects against vibration and interference! Head Box S2 Digital comes in silver or black.
