The Fostex HP-P1 Headphone Amplifier & D/A Converter is a portable headphone amplifier with a D/A converter that receives its audio signal digitally from your iPod/iPhone 30-pin dock connector. It's designed to provide exquisite tone, depth and effective headroom for unsurpassed sonic performance and fidelity. The HP-P1 features a 3-step gain control to accommodate all types of headphones, as well as a built-in S/PDIF digital out.
This headphone amp employs AKM's 32-bit AK4480 DAC, which offers on-chip symmetrical circuitry to avoid noise coupling, thus improving sound quality. It has two digital filters including a 32-bit minimum delay filter designed specifically for acoustic sounds. Engineered from aircraft-grade aluminum and built to exacting standards, the HP-P1 is a delight to handle and operate. Also included is a carrying case that can be clipped to a belt for easy transport.
