Exquisite Sound

DAC 2*CS43131  SNR -131dB

Compared to a single-chip solution, the dual CS43131 delivers clearer sound details and a more three-dimensional soundstage. Whether you're listening to vocals, symphonies, or pop music, you'll hear more authentic, nuanced sound. Meanwhile, the dual-chip architecture achieves an ultra-high signal-to-noise ratio of -131dB, completely eliminating electrical background noise.

Excellent output drive ability

Dual-chip design with independent left and right channels

With the 4.4mm balanced output, it delivers a powerful 180mW+180mW, effortlessly driving a wide range of high-impedance over-ear headphones and low-sensitivity earphones. Whether it's the explosive impact of large-scale dynamic symphonies or the refined warmth of delicate vocals, every nuance is perfectly rendered.

Enhanced headphone compatibility

More flexible and stronger adaptability

Three adjustable power levels suit any headphone (from tiny earbuds to large over-ears) regardless of impedance or sensitivity. Hardware-based adjustment provides stable, cleaner sound — no more under-driving, weak vocals, or noise. Every headphone reaches its full potential.
