“A gatekeeper into the realm of high-performance headphone amplification” – John Darko, Darko Audio

Head Box S2 Digital supports playback for PCM files up to 32bit / 768kHz and DSD decoding up to quad DSD (DSD256). The Head Box S2 Digital also comes with five digital filters for shaping the listener’s preferences. The front seated 6.35mm headphone output delivers a clean and precise sound with a musical touch.
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. 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 to realize an undisturbed listening experience. The new aluminum/metal casing ensures the highest aesthetics and protects against vibration and interference!
