Superior D/A conversion & outstanding headphone sound for digital and analogue sources combined in one box!
Head-Box DS is based on the former SE model, which has a very good sound quality, but only one analogue input. So we kept a similar concept, improved the power supply and added a high-quality digital section! It’s USB input works up to 24/192 in asynchronous mode! Playback for any headphone offers realistic sound-staging on all volume levels for 3 digital and 1 analogue sound source. Head Box DS also provides a high-quality front display, that gives full information on current status.

Can be used as DAC? Yes, internal D/A conversion offers additional RCA line output that can be used with any hifi-system as cost-effective sound upgrade for existing digital sound sources. As DAC Box DS, Head Box DS uses feedback loop for controlling computer and amount of data sent. This allows implementation of a high quality, fixed frequency clock directly in the DAC section to keep jitter as low as possible.
