S.M.S.L D200 Desktop DAC & Preamp
The S.M.S.L D200 is a high-performance desktop digital-to-analog converter and preamplifier built around the ROHM BD34352EKV DAC chip. Designed for audiophiles seeking clean, linear sound with excellent measured performance, it combines ultra-low distortion, versatile connectivity, external clock support, and full MQA decoding in a compact aluminum chassis ideal for modern desktop systems.
ROHM BD34352EKV DAC Architecture
At the core of the D200 is the ROHM BD34352EKV 32-bit DAC chip, selected for its high linearity and natural tonal character. Paired with dual NJU72315 chips in a fully balanced preamp stage, the design achieves THD+N as low as 0.00019% (-114 dB) and SINAD up to 115.9 dB. This architecture delivers transparent, detailed reproduction with precise imaging and low noise across the entire frequency range.
SMSL CK-03 Clock Circuit with External Clock Input
The D200 incorporates SMSL’s self-developed CK-03 clock processing circuit to significantly reduce jitter. It also features a dedicated external clock input that accepts a standard 10 MHz reference or atomic clock, allowing users to further improve timing accuracy when pairing with a high-precision master clock source.
Full MQA and High-Resolution Audio Decoding
The D200 provides comprehensive support for high-resolution formats. Via USB it handles PCM up to 32-bit/768 kHz and native DSD up to DSD512. Optical and coaxial inputs support PCM up to 24-bit/192 kHz and DoP DSD64. Full MQA and MQA-CD decoding is available on USB, optical, and coaxial inputs, enabling studio-master quality playback from compatible sources.
High-Performance Qualcomm Bluetooth Connectivity
Equipped with a Qualcomm Bluetooth chipset, the D200 supports LDAC (24-bit/96 kHz), aptX HD, aptX, AAC, and SBC. The unit can display track information and lyrics while offering wireless playback control, delivering convenient high-resolution streaming from smartphones, tablets, and computers without compromising audio quality.
Balanced and Single-Ended Outputs with Preamp Function
The D200 offers both balanced XLR (up to 5 Vrms) and single-ended RCA (up to 2.5 Vrms) outputs. It functions as a high-quality preamplifier with volume control or can be set to fixed output mode, making it easy to integrate into a wide range of systems from active speakers to power amplifiers.
Linear Power Supply and Tempered Glass Display
A linear power supply with SMSL’s patented Adaptive Voltage Switching technology supplies clean power to the analog stages. The front panel features a 1.9-inch fully laminated tempered glass display with high light transmittance, supporting Chinese and English interfaces for clear status and menu navigation.
Comprehensive Digital Connectivity
The D200 provides a full set of digital inputs for versatile system integration:
- USB Input: Powered by XMOS XU-316 supporting high-resolution PCM and native DSD.
- Optical & Coaxial Inputs: Suitable for connecting televisions, game consoles, CD transports, and other digital sources.
- Bluetooth Input: High-resolution wireless streaming with LDAC and aptX HD support.
