The HP-A3 32-Bit D/A Convertor with Headphone Amp from Fostex is a digital to analog audio convertor 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 convertor from USB to optical.
