About

An active dongle DAC using the Cirrus Logic CS46L06 chip at 24-bit/48kHz — the US-market unit (A2049) outputs 1.0Vrms at 0.9Ω output impedance, while the EU-market unit (A2155) is firmware-limited to 0.5Vrms to meet EU sound-pressure regulations, a 6dB drop in headroom for demanding headphones.

Ports: 1× 3.5mm audio jack and 1× USB-C
