miniature high quality digital to analogue converter!

DAC Box S2 + 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). DAC Box S2 + 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 datas up to 24bit /192kHz. The USB input offers full high resolution support for all files up to PCM 32/768 and DSD256. Unwanted noise coming in through USB is double filtered to suppress them to a level where it can’t affect audio. The new aluminium/metal casing ensures highest aesthetics and protects against vibration and interference!
