The modern-looking D400Pro DAC (digital-to-analogue converter) is based on an AK4191 and an AK4499EX chip, capable of decoding PCM data streams up to 32 bit 768 kHz and native DSD up to DSD512. A third-generation XMOS XU-316 USB interface and CK-03 clock circuitry further contribute to precise audio reproduction. In addition to MQA and MQA-CD decoding, the D400 Pro also supports aptX HD and LDAC quality wireless audio via Bluetooth 5 connectivity. The superbly designed DAC is built with quality components and is as versatile as it is powerful. A remote controller is included.
