The SMSL DO300 digital-to-analogue converter promises detailed and accurate audio reproduction with a flagship ES9039MSPro DAC chip, 32bit 768kHz DSD512 resolution and MQA-CD decoding via an XMOS XU-316 USB interface chip. Bluetooth 5 wireless connectivity is provided by a QCC5125 chip, supporting aptX, aptX HD and LDAC codecs.
In addition to single-ended RCA and balanced XLR outputs, there are AES/EBU, I2S, COAX, optical, Bluetooth and USB-B inputs. The front panel colour IPS display, protected by tempered glass, is easy to read and can be switched off freely.
The DO300 offers a more precise, neutral sound character compared to its DO200 MKII sibling, but it's still a versatile DAC with excellent performance. The package also includes an RC-8C remote control, Bluetooth antenna, EU power cable and USB-B cable.
