HP-A8C is Fostex\'s flagship 32bit DAC / Headphone Amplifier model and features finely designed Analog and Digital circuitries as well as the epoch-making DSD audio playback function.

Housed in a gorgeous enclosure featuring glass front panel and black side panel, the HP-A8C is set to spark the interest of both high-end headphone users as well as PC audio makers, professionals and enthusiasts.

Partner with the new TH-900, premium headphones for excellent results.

• High fidelity 32bit D/A converter (Asahi Kasei\'s AK4399) and all discrete analog circuitry headphone amplifier.
• Complies with USB Audio Class 2.0 up to 32bit / 192kHz (24bit on Windows)
• Asynchronous mode by highly precise TCXO (Temperature Compensated Cristal Oscillator) clock.
• Highly precise level adjustment by an electronic volume designed for audio equipment.
• Large capacity toroidal power transformer.
• Built-in SD (SDHC) card drive for epoch-making DSD file (DSF format) reproduction in addition to the firmware update.
• Selectable between the internal clock and the external clock (except for USB and SD card)
• Built-in up-sampling function of x 2 and x4
• Digital Filter selection between the conventional \"sharp roll-off\" and the \"minimum delay\" developed by Asahi Kasei to eliminate pre-echo.
• Direct Out mode bypassing the volume control circuit.
• Variable headphone amplifier\'s gain from 0dB to -12dB by 0.5dB step for perfect match with any type of headphones.
• Various inputs including USB, AES/EBU, Coaxial, Optical (x2) and analog RCA.
