SMSL D100 Office All-in-One Headphone Amp DAC, ES9081 XMOS XU-316 Chip, MQA/DSD512 Compatible, 1/4" Balanced Output, RCA Preamp, Suitable for Active Speakers

Equipped with the ESS ES9081 DAC chip and third generation XMOS XU-316, it supports full decoding of native DSD512, 32bit/768kHz PCM and MQA format. Multi-channel coordination generates a deep stereophonic scene and extreme fidelity, satisfying the strict requirements of audiophiles. Featuring two headphone outputs: balanced 1/4" and asymmetric 1/4". It provides powerful drive force (400mW ×2 under 32Ω), capable of powering large high impedance headsets easily. Its ultra-low background noise design (<0.83μVrms) provides a completely silent background sound that is perfectly suited for high-sensitivity in-ear headphones. Digital signal circuits and power circuits are physically separated to suppress any electromagnetic interference. A Type-C socket for auxiliary power is built-in: when decoding on phone or tablet, the mobile device does not consume its battery, resulting in a more pure and stable audio signal. RCA line output with pre-amplified volume control allows you to connect active speakers or power amplifier directly to form a desktop HiFi system. It also offers intense dynamic response without latency, giving PC gamers an immersive and striking 3D auditory localization experience. The housing is made of 100% high-precision CNC machined aluminum, equipped with a 1.66 inch anti-scratch tempered glass screen. The interior incorporates two ultra-low phase noise NDK oscillators, TI OPA1612A operational amplifiers and several low-noise LDO controllers, achieving total harmonic distortion plus noise (THD+N) down to 0.00033% for outstanding audio performance.
