HP-A8mk2
DAC Headphone Amplifier
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).
