The Bitzie USB DAC from Graham Slee is a highly capable and sonically sophisticated piece of audio equipment. This unit provides a truly immersive experience, providing a vast sense of space and depth, tempered with impeccable clarity and detail. 

This DAC is also highly user-friendly, and is essentially plug-and-play, with no sitting around and waiting for irritating downloads. The Bitzie is compatible with most operating systems as soon as its plugged in. The unit works like an external soundcard, and so is a great option for people who have a S/PDIF only DAC but want to be able to retrieve their music collection from USB. 

The Bitzie also features both coaxial and optical outputs, and will deliver phenomenal performance when used as a headphone amplifier, for both low-impedance and high-impedance headphone sets
