Graham Slee Bitzie USB DAC

The palm size "bus-powered" Bitzie hi-fi USB DAC will easily match the sound of much bigger DACs. It will drive a power amplifier, active loudspeakers, and as a hi-fi USB headphone amp — headphones. And at the same time it will convert USB to transformer-driven coax or optical S/PDIF and send to other devices — it's a hi-fi USB to optical converter and a hi-fi USB to coax converter. And now with its optional "power wire" (available separately), it can grab its power from other 5V sources including Virgin Atlantic USB "in-seat power" or a phone charger, as well as being made to sound even better.
