Graham Slee is a small, enthusiastic manufacturer of realistically priced, high performance phono stages and headphone amplifiers, designed and built by hand in Yorkshire since 2003. Very positively reviewed by UK and international magazines, demand for these products has been overwhelming as the world's hifi enthusiasts can't believe the performance on offer for the price asked.

Each unit is designed by owner/ engineer Graham Slee and then hand constructed by two skilled electronics engineers before being thoroughly tested to check it meets it's specification and is 100% reliable.

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
