The Lyreman DAC-01 is a desktop DAC featuring USB-C optical inputs, designed to convert various digital sources and drive a headphone or an audio setup. Its ES9039Q2M converter accepts PCM streams up to 768 kHz/32 bits and DSD512 over USB-C, while its 3.5 mm single-ended and 4.4 mm balanced headphone outputs ensure integration suited to multiple configurations.
The amplification delivers up to 500 mW per channel on the 3.5 mm output and 1,000 mW per channel on the 4.4 mm output into 32 Ω, allowing it to drive demanding headphones. A line output completes this versatility for connection to active speakers or an external amplifier, making the DAC-01 a central conversion point for a desktop system.
