S.M.S.L - DO200 DAC - 数字模拟转换器

Compact and sober, the SMSL DO200 high-resolution DAC has a metal build, premium finishes, and pairs perfectly with the AO200 stereo amplifier from the same manufacturer. It includes a 1.9” tempered glass display (IPS type with dimming function), next to the central volume/select knob.

The DO200 houses a pair of ESS DAC chips (ES9068AS) to support fully balanced output. It also features five SoundPlus OPA1612 op-amps, quite common, and is capable of handling high-resolution files including DSD512 and PCM up to 768 kHz / 32 bit. The USB input is supported by an XMOS XU-216 interface and the DO200 includes LDAC, aptX and Bluetooth 5.0 inputs. In fact, the DO200 is currently the only DAC on the market to offer complete MQA decoding on all inputs, including USB, optical, coaxial and even the AES serial interface. MQA playback does not require additional software; Foobar2000 or Audirvana can be used for playback since it supports ASIO or WASAPI audio output (it is recommended to set the computer’s volume to the maximum possible).

As for refinement, it is a desktop DAC of standard size among the very few, if not the only, ones that natively support LDAC and aptX HD. On the back there are balanced XLR outputs as well as single-ended RCA outputs, AES/EBU inputs, Bluetooth antenna, exotic I2S input, coaxial, optical and USB inputs. Next to the power socket is the physical power switch; the small remote control is included in the package. PCM filters available: “Slow Minimum”, “Minimum Phase” and “Fast Linear”; for DSD or MQA support on coaxial & optical inputs you must enable processor mode (then power off and restart the unit), invoking XMOS rather than using the DIR (Digital Interface Receiver) chip as is often done with other DACs. There is also a DPLL (Digital Phase-Locked Loop) function to limit jitter and avoid interruptions when the input source is poor. Among the specifications: THD+N 0.00008%, dynamic range 129 dB on XLR and 125 dB on RCA, SNR 128 dB, output impedance 100 Ohm. Bluetooth compatibility with SBC / AAC / APTX / APTX HD and LDAC. USB bit depth: 1 bit, 16-32 bit; optical/coaxial/AES/EBU: 1 bit, 16-24 bit. Power consumption 5 Watts; the low-noise linear power supply is a discrete component designed to improve energy efficiency and reduce consumption. Dimensions 210 x 40 x 170 mm (L x H x D) and weight 1.2 kg.

Used very little, the best DAC value for money. In the box: a pair of XLR cables as a bonus.

Thank you
