SMSL D100 DAC Headphone Amplifier XMOS XU-316 ES9081 32bit 768kHz DSD512 Silver
The SMSL D100 is an all-in-one desktop DAC and headphone amplifier built around the ESS ES9081 chip, using all eight channels in parallel summing mode to achieve a dynamic range of 127dB. Supporting PCM streams up to 768kHz, DSD512, and MQA decoding, it ensures extremely high-precision digital-to-analog conversion.
Its balanced headphone amplification stage delivers up to 400mW and supports headphones with impedances of up to 600Ω. The D100 features two front-panel headphone outputs (single-ended 6.35mm jack and balanced 4.4mm jack) as well as a rear stereo RCA line output, which can operate in either fixed or variable mode for use as a preamplifier.
Its digital connectivity relies on two independent USB-C ports, one dedicated to power and the other to data, in order to isolate noise generated by computers or prevent smartphone battery drain. The whole unit is housed in an elegant CNC-machined aluminum chassis and features a 1.66" glass-covered color display with a user-friendly interface.
SMSL D100: High-resolution ESS ES9081 DAC
The SMSL D100 is based on the ESS ES9081 converter, a professional-grade chip employed here in an eight-channel parallel summing architecture. This design enables a dynamic range of up to 127dB while ensuring extremely detailed sound reproduction. The D100 supports high-resolution audio files up to PCM 32bit 768kHz, native DSD512, and MQA decoding, providing broad compatibility with demanding music libraries and streaming services.
SMSL D100: Balanced headphone amplifier
The D100 incorporates a true balanced headphone amplification stage designed to provide silent and accurate sound reproduction. It features a single-ended 6.35mm jack output and a balanced 4.4mm Pentaconn output, capable of driving a wide variety of headphones, including high-impedance models up to 600Ω. With a maximum output power of 400mW, it delivers dynamic and controlled listening performance suitable for both portable headphones and audiophile reference models.
SMSL D100: Preamplifier function and Volume control
Thanks to its RCA line outputs, the SMSL D100 can be used either as a pure DAC or as a preamplifier. Its integrated volume control allows direct adjustment of the output level to drive a power amplifier or a pair of active speakers. The line outputs can therefore operate at either fixed or variable level depending on the system requirements. This versatility helps simplify a Hi-Fi setup while maintaining precise volume control directly from the D100 itself.
