Main Features

• Headphone amplifier equipped with high-quality sound 32bit-DAC (AK4490) and all discrete circuit.
• Supports a sampling frequency of up to 32 bit/192 kHz through in house developed USB driver. In addition, supports DSD 11.2 MHz (ASIO).
  * DSD playback on Mac is compatible up to 5.6 MHz
• Eliminates the jitter caused by low accuracy of the source clock of the computer, etc. by using the asynchronous mode of an SPXO for audio (crystal oscillator).

Product Description 

Fostex HP-A8 Mk2 Headphone Amplifier + DAC is a high-calibre, easy to use combined model that truly brings life to your headphones. Kick back and enjoy top quality digital sounds from your computer or any other digital audio device.

The HP-A8 Mk2 showcases a 32-bit DAC alongside subtle circuitry within a sleek and aesthetically pleasing construction.Thanks to its bespoke USB driver, the model supports a sampling frequency of up to 32 bit/ 192 kHz.

Attention to Detail

Jitter is eliminated from the model thanks to the utilisation of a crystal oscillator in the asynchronous mode.

Ultra-Connected

Input sources can be provided by computers, digital and analog audio devices. The model can play DSF files, WAV files and AIFF files on an SD (SDHC) card directly by utilising the built-in SD (SDHC) card drive. This drive is future-proof for upcoming updates.

Feature Rich

The HP-A8 is excellently versatile as both the external and the external clock are available for the master clock, alongside being equipped with an RCA pin jack output.

The headphone output is improved by 24 level gain settings, while the model also enjoys a switchable digital filter. Sound clarity and accuracy is increased as analogue output does not directly pass through the volume.
