Built around the ESS ES9081 DAC chip and XMOS XU-316 USB processor, it delivers excellent measured performance, full MQA support across all digital inputs, and a true balanced headphone output up to 400mW, making it an ideal all-in-one solution for desktop listening and active speaker systems.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003eESS ES9081 DAC with 8-Channel Parallel Summing\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eAt the heart of the D100 is the ESS Technology ES9081 DAC chip configured with 8-channel parallel summing architecture. This design achieves low distortion of 0.00035% (-109dB) on the RCA line output and a dynamic range of up to 121dB. Paired with the XMOS XU-316 asynchronous USB processor, the D100 supports true 32-bit high-resolution audio and provides transparent, highly resolved sound reproduction.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003eHigh-Resolution Audio and Full MQA Decoding\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eThe D100 natively supports PCM up to 32-bit\/768kHz and native DSD512 via USB. Optical and coaxial inputs handle PCM up to 24-bit\/192kHz. Full MQA decoding is available across all digital inputs—USB, optical, and coaxial—allowing users to enjoy master-quality audio from streaming services, MQA-CDs, and digital transports without compromise.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003eTrue Balanced Headphone Amplifier\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eFeaturing a true balanced headphone amplifier circuit, the D100 offers both 4.4mm balanced and 6.35mm single-ended outputs. It delivers up to 400mW × 2 into 32Ω and supports headphones up to 600Ω. The low noise floor and clean power delivery make it suitable for sensitive IEMs as well as efficient full-size headphones, providing clear dynamics and a quiet background.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003eIndependent Dual USB-C Design\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eThe D100 incorporates two separate USB-C ports—one dedicated to audio data and the other for auxiliary power. This physical separation helps minimize ground-loop noise and power interference from computers while also allowing external power when connecting to smartphones or tablets, reducing battery drain on mobile devices.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003eRCA Line Output with Preamp Function\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eIn addition to headphone outputs, the D100 provides a high-quality RCA line output rated at 2Vrms. Volume control can be applied to the line output, enabling the unit to function as a digital preamplifier for active speakers or external power amplifiers in a compact desktop setup.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003ePremium CNC Aluminum Chassis and Display\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eHoused in a precision CNC-machined aluminum alloy chassis measuring 127 × 31.7 × 126.7 mm and weighing only 338g, the D100 offers excellent build quality and electromagnetic shielding in an ultra-compact footprint. A 1.66-inch fully laminated tempered glass display provides clear status information with a modern, clean aesthetic.\u003c\/p\u003e\n\u003ch3 dir=\"auto\"\u003eAbout SMSL\u003c\/h3\u003e\n\u003cp dir=\"auto\"\u003eFoshan ShuangMuSanLin Electronics Co., Ltd.
