SMSL SU-3 Digital to Analog Convertor SU3 USB DAC HIFI Decoder AK4496 Chip Decoding

Description Report this item or seller SMSL SU-3 High-Resolution DAC with 32-Band PEQ Equalization Compact Design with Multiple Placement Options Features AKM AK4496 DAC for ultra-low distortion Dual femtosecond clocks for pure timing accuracy New-generation XMOS XU-316 with PCM768kHz & DSD512 32-band PEQ with power-off memory High-performance USB power filtering XLR balanced output for studio-grade signal Anodized CNC aluminum alloy chassis Compact design with multiple placement options Ultra-Low Distortion with AKM AK4496 DAC To deliver a pure and flawless sound, the SU-3 uses AKM's AK4496 decoding chip, known for its excellent signal conversion and very low noise. After many rounds of acoustic adjustments, circuit improvements, and careful tuning, the chip's performance is refined and the signal path is optimized. This helps prevent signal loss and harmonic interference, achieving ultra-low distortion as low as 0.00012 (-118dB). The result is clear sound, smooth frequency transitions, detailed dynamics, and faithful music reproduction. Rebuilding Pure Timing Soundstage The accuracy of timing has a direct effect on the purity of sound, since even a small amount of clock jitter will damage the integrity and clarity of the audio. The SU-3 is equipped with two high-precision, low-phase-noise femtosecond crystal oscillators, which serve as the main clock reference for the device. This allows clock jitter to be compressed, phase noise to be reduced, and the transmission timing of each group of audio signals to be accurately controlled, making the process of digital signal conversion more stable and accurate. Unlock Full-Frequency High-Resolution Soundstage The SU-3 is equipped with a new-generation XMOS XU-316 high-end audio master control system. Owing to its powerful multi-core computing capabilities and well-developed audio processing architecture, it fully supports a high PCM sampling rate of 32bits/768kHz and is compatible with DSD512 ultra-high-rate lossless audio decoding. This allows it to accurately capture the subtle overtones, airiness, and dynamic details in music. Whether it is delicate vocals, a grand symphony compilation, or a pure instrumental solo, it can reproduce them completely. Exclusive Personalized Setting with 32-Band PEQ Considering both professional sound quality and the need for personalized listening, the SU-3 is fitted with a professional audio tuning feature and offers a 32-band fine PEQ balanced adjustment that covers the entire audio tuning range. It is able to make fine adjustments to different types such as vocals, pop, classical, and rock music, as well as to individual listening preferences and equipment characteristics. The SU-3 also has an EQ power-off memory function, so exclusive equalization settings do not need to be set again and can be automatically saved and recalled after a restart. High-Performance Power Supply and Pure Signal Link The SU-3 is equipped with a high-performance dedicated power filter system that accurately filters out noise, ripple, and electromagnetic interference that occur during the power supply process, stabilizing both voltage and current output. Even when powered only through the standard USB interface, the chip, crystal oscillator, and decoding module remain in a stable operating condition. The SU-3 also features an XLR balanced line output interface with strong anti-interference capability, effectively shielding electromagnetic interference, signal attenuation, and noise crosstalk during transmission. Precision Texture and Adaptable Design The SU-3 features an anodized CNC aluminum alloy shell, cut and formed with high-precision CNC machining. The surface is smooth with finely finished corners, and the mature anodizing process ensures scratch resistance and worry-free use. The compact, integrated body design minimizes its footprint and supports multiple orientations, including flat, vertical, and side placement. It adapts effortlessly to various scenarios such as desktop audio and video, bedroom listening, study listening, and portable external connections, easily blending into diverse aesthetic atmospheres.
