A DAC, MM phono preamplifier, preamplifier, headphone amplifier and powerful power amplifier are combined in one compact case (210×46×254 mm, weight 1.56 kg). The Cirrus Logic CS43131 chip is responsible for the sound quality. The built-in USB interface is built on the XMOS XU-316 circuit. The power amplifier based on Infineon MA5332MS modules produces 2×85 W at 8 Ohm or 2×165 W at 4 Ohm. There is a volume control on the NJW1194A (JRC) chip.
