DAC Box S2+ comes fully equipped for the highest demands of the modern digital audiophile. It supports playback of PCM files up to 32bit/768kHz and DSD decoding up to quad DSD (DSD256). DAC Box S2+ also includes five digital filters for sound-shaping to your liking. Three digital inputs ensure compatibility with numerous sources such as a personal computer via the asynchronous XMOS USB B input or a TV set via the optical input. The coaxial S/PDIF input takes all the digital data sent by a CD transport as well. 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 32bit/768kHz and DSD256. Unwanted noise coming in via USB is double-filtered making it inaudible in playback. The simple, sleek-looking aluminum/steel enclosure is protective against vibration & airborne interference helping to foster optimal sonic performance.
