* A power-house to drive even the most demanding full-sized headphones, along with a dedicated mini phone jack tailored for in-ear-monitors.
* Pure tube design without the use of semi-conductors in the amplification circuitry. The 6C45 triode acts as both driver and power tube.
* The USB input supports up to 32/192k high-res playback. The RCA connectors can be used either as analog inputs or as D-A outputs. Both in/out signals are user selectable on the back panel.
* The linear external power supply provides pristine energy to the amplifier. It can be placed where ever you please to keep the simplicity of the unit.
