The HP-A3 32-Bit D/A Converter with Headphone Amp from Fostex is a digital to analog audio converter designed for computer audio output. It is capable of handling up to a 24-bit, 96kHz digital audio source.

It features two analog outputs choices: two RCA line outs or a ¼” headphone out, powered by its built-in headphone amplifier. The HP-A3 has two digital input options; either USB or optical S/PDIF. It also features an S/PDIF digital output, which allows the unit to act as a digital to digital converter from USB to optical. The unit is USB bus powered regardless of input routing choice and does not have a separate AC input. The input and output routing is selectable by front panel selector buttons.
