Aune Yuki SE
ES9280AC Pro Portable Dongle DAC

The Yuki SE, Aune's new portable DAC with headphone amplifier, is equipped with the ES9280AC Pro DAC chip. The innovative dual-layer structure separates the digital circuitry from the analogue headphone amplifier circuitry. The 4-way balanced headphone amplifier circuit utilises 4×4 transistors to drive the output optimally. This high-quality "dongle" is the perfect addition to your smartphone, tablet, computer, laptop and console.

Descriptions:

Discrete Headphone Amplifier with Transistors - Detailed music playback
Most dongles use integrated designs where the amplifier chip is fixed, which limits the range of settings. Aune, on the other hand, has tested over a hundred combinations of transistors, resistors and capacitors based on their own understanding of audio and according to their own requirements. The result is a dongle DAC that consists of 16 transistors and forms the 4-way headphone amplifier that produces the desired sound. 

Independent ESS DAC chip - High Resolution
Equipped with the ES9280AC Pro DAC chip, the Yuki SE supports decoding in master tape quality up to 32-bit/768k DSD512 and provides you with an unrivalled precise and detailed music experience.

Dual Structure - DAC and amplifier completely separated
The innovative dual-layer structure completely separates the DAC and headphone amplification - one layer for the digital DAC circuit and the other for the headphone amplifier circuit. The Yuki SE has been designed with true high-fidelity playback in mind.

Turn your smartphone/pad into a Hi-Res player
Connect your smartphone/pad to the Yuki Se via USB and the sound quality is massively improved. It can be that easy to enjoy Hi-Fi anywhere and anytime.

The computer's little Hi-Fi Friend - 32 Bit/768k DSD512 High-Resolution Decoding
Connect the Yuki SE to your computer/laptop via USB. No drivers are required. A high-resolution sound experience with 32 bit/768k DSD256 can be so easy.

The special dongle DAC - ±5V boost design
The Yuki SE utilises multiple DC-DC power management chips to ensure multi-stage noise suppression and precise voltage regulation. This ensures a stable power supply for the balanced four-way transistorised headphone amplifier. Despite its compact size, this device offers impressive performance.

Femtosecond Clock - Rich and refined sound
The Yuki SE utilises two precise AS318 crystal oscillators to provide stable clock signals for the digital core chips, resulting in a particularly natural sound reproduction.

Two Headphone outputs - Outstanding compatibility
The Yuki SE with ESS DAC chip, the independent four-way headphone amplifier with ±5V power supply and the balanced 4.4mm and unbalanced 3.5mm headphone sockets can easily drive different headphones.

The Window to Technology - Aesthetic sophistication
The Yuki SE continues Aune's classic transparent window design and combines an aluminium structure with an aesthetically pleasing overall design. This allows you to experience the harmonious fusion of art and technology.

High-Spec - The basis for outstanding sound
The output noise of the headphone amplifier is only 2.9 μV with a THD+N of 0.00050 % at 1 kHz. This outstanding hardware performance forms a solid basis for first-class sound.
