D100

S.M.S.L D100 Ultra-Compact High-Resolution DAC & Headphone Amplifier

The S.M.S.L D100 is a highly versatile, ultra-compact desktop DAC and headphone amplifier designed to deliver an audiophile-grade listening experience in a small, elegant footprint. Equipped with a premium ESS DAC chip, XMOS asynchronous USB processing, and support for balanced headphone outputs, it offers an incredible price-to-performance ratio for music lovers and desktop audio enthusiasts alike.

High-Fidelity ESS ES9081 DAC & XMOS XU-316

Featuring the high-performance ESS Technology ES9081 decoding chip, the D100 achieves an ultra-low distortion of just 0.00036% (-108dB). Paired with the state-of-the-art XMOS XU-316 USB processor, it offers a true 32-bit asynchronous USB solution. It supports high-resolution audio formats up to 768kHz PCM, native DSD512, and DoP, delivering a transparent and faithful reproduction of the original master recording.

Full MQA Decoding Across All Digital Inputs

Unlike standard DACs that only support MQA decoding via USB, the D100 provides full MQA (Master Quality Authenticated) decoding across all of its digital inputs—including USB, Optical, and Coaxial. This allows you to experience master-quality streaming and MQA-CD playback from optical or coaxial-connected CD players with ease.

Integrated Balanced Headphone Outputs & Clean Power

The D100 features a built-in balanced headphone amplifier circuit with both a 4.4mm balanced and a 6.35mm single-ended output. On the rear, a dedicated single-ended RCA output allows you to connect to active monitors or external amplifiers. The internal circuitry utilizes multiple low-noise voltage regulators to supply pure, interference-free power specifically to the sensitive analog stages, resulting in a dark background and a wide, holographic soundstage.

Auxiliary 5V Power for Safe Mobile Connectivity

To protect your smart devices, the D100 features a dedicated 5V auxiliary power input. When connecting the device to a smartphone or tablet, connecting an external 5V power supply to this port prevents the D100 from drawing excessive power from your phone, eliminating the risk of battery strain or damage to your source device.

CNC Aluminum Chassis & Fully Laminated Display

Housed in a precision-engineered, CNC-machined all-aluminum alloy chassis with gold-plated input and output connectors, the D100 is built with premium craftsmanship. The front panel features a 1.66-inch fully laminated tempered glass display panel, which offers high light transmittance, an intuitive user interface, and long-lasting durability. The entire system is Japan Audio Society (JAS) Hi-Res certified.
