Introduction


Fostex, known by many for their T50RP orthodynamic headphones recently released an innovative i-devices accessory. The HP-P1 unit allows for extraction of digital out from any modern Apple i-device. Unlike the analog line-out from the i-dock, the digital does not have to pass through the unit's internal DAC and therefore leaves the unit completely untouched. The HP-P1 can then via its own elaborate DAC setup convert the digital out to an analogue signal, and the trick here is that the HP-P1 uses a high quality DAC and amplification stage unlike anything ever incorporated into an i-device.

The HP-P1 can effectively turn any i-device into a high-performance headphone source or DAC. Fostex have graciously provided the HP-P1 with both analogue out and optical S/P-DIF.
