The modern-looking D400Pro DAC (digital-to-analog converter) is based on an AK4191 and an AK4499EX chip, which can decode PCM data streams up to 32 bit 768 kHz and native DSD up to DSD512. A third-generation XMOS XU-316 USB interface and the CK-03 clock circuit also contribute to precise sound reproduction. In addition to MQA and MQA-CD decoding, the D400 Pro also supports aptX HD and LDAC quality wireless audio via Bluetooth 5 connection. The superbly designed DAC is built with quality components and is as versatile as it is powerful. The package also includes a remote control.
