The DAC section is built on a dual CS43198 chip from Cirrus Logic, and signal amplification is provided by two SGM8262 modules from SG Micro. The maximum output power is 500 MW at 32 ohms with balanced connection, and the low output resistance, not exceeding 0.4/0.8 ohms, allows the amplifier to confidently handle most headphones.
