Featuring an ultra-high quality 32-bit DAC and exclusively designed audiophile analogue circuitry, the sonic performance and fidelity of the headphone signal simply has to be experienced to be believed. The tone, the depth and the effective headroom is nothing short of stunning, giving the impression of almost limitless audio power reserves on tap at all times.

Add to this a 3-step gain control to accommodate all types of headphones, an onboard S/PDIF Digital Out, twin digital filters and a rugged, yet cool, aluminum alloy chassis and you simply have the best portable headphone amp for your iPod / iPhone available.

Everything about the Fostex HP-P1 screams quality. - First up is the audio processing.
