Overview
New standard model for easy enjoyment of balanced headphones
A new standard model based on the HP-A4 headphone amplifier with built-in DAC for easy enjoyment of balanced headphones.
Features
- Equipped with XLR (4-pole) balanced output terminals.
- Newly developed audio capacitors are used.
- Low phase noise high-precision crystal (crystal oscillator) is used.
- 24bit/192kHz linear PCM audio and 11.2MHz DSD audio can be played back.
- When used with MacOS, DSD up to 5.6MHz is supported.
- High-performance DAC (Burr Brown PCM1792A).
- USB AUDIO2.0 compatible with 192 kHz/24 bit asynchronous.
- HI/LO gain switch (10dB) supports a wide range of headphones.
- Equipped with a digital filter that allows switching of roll-off characteristics and cut-off frequency according to the sound source.
