The SMSL D400EX is equipped with the latest generation of AKM digital/analog converter with two AK4499EX chips and one AK4191 chip. These chips are extremely powerful and ensure a very musical sound reproduction for a lively and immersive listening. These chips are integrated in a dual mono design with one AK4499EX chip per channel.
The USB input of the D400EX features a XMOS XU316 USB interface. This high-performance microcontroller allows fast and efficient processing of audio streams via USB. It also guarantees support for PCM signals up to 32bit 768kHz and DSD up to DSD512.
With its AK4499EX chips, the D400EX becomes capable of decoding and playing the MQA (Master Quality Authenticated) format. This type of file offers a high sound quality, as close as possible to the original studio recording. Each track is also authenticated by the artist, producer or copyright holder. This type of format is notably used on the Tidal streaming platform. In addition, MQA-CD is also supported, allowing this type of file to be played from a CD player.
In addition to its already complete connectivity, the D400EX integrates a Bluetooth 5.0 receiver from Qualcomm. This one offers the possibility of broadcasting and controlling its music in wireless, from a smartphone or a tablet for example. The receiver chip used supports the high-resolution transmission codecs aptX HD and LDAC for a quality sound reproduction in Bluetooth.
The whole D400EX benefits from a quality design, using only components specially selected for their performance. It includes a circuit with no less than 9 dual operational amplifiers, the brand's CK-03 clock system for greatly reduced jitter and a regulated low-noise power supply stage.
