Yuki SE, aune's new portable DAC with headphone amp, is equipped with the ES9280AC Pro DAC chip. The innovative double-layer structure separates the digital circuit from the analog headphone amp circuit. The 4-way balanced headphone amp circuit has 4x4 transistors to drive the output. It is a high-quality "dongle" that's great for your smartphone, tablet, computer, laptop and Switch. Equipped with the ES9280AC Pro DAC chip, the Yuki SE supports master-tape-gradedecoding up to 32bit/768k DSD512, providing you with a high-resolution music experience. The Yuki SE adopts two low-jitter AS318 crystal oscillators to provide clock signals for the core digital chips, resulting in a more natural sound. The Yuki SE uses multiple DC-DC power management chips for multi-stage noise reduction and voltage regulation, ensuring the power supply for the balanced four-way discrete transistor headphone amplifier. This little thing has got big power inside. The Yuki SE continues aune's classic transparent window design, with an all-aluminum structure and overall aesthetic design, allowing you to experience the wonderful fusion of art and technology. High-Spec The Foundation of Excellent Sound Headphone amplifier output noise: 2.9uV, THD+N: 0.00050% @1kHz. The excellent hardware performance has laid a solid foundation for excellent sound.
