Aune Yuki SE - Portable Headphone Amplifier

Yuki SE from Aune is a high-performance portable DAC with a headphone amplifier, equipped with the advanced ES9280AC Pro DAC chip. The innovative dual-layer structure separates the digital circuit from the analog headphone amplifier, optimizing performance. With a 4-way balanced amplifier circuit using 16 transistors (4×4), Yuki SE delivers a powerful and precise audio experience. This high-quality "dongle" is the perfect accessory for your smartphone, tablet, computer, laptop, or gaming console.

• 4-way discrete balanced amplifier circuit
• 4 x 4 transistors
• DAC-chip: ES9280AC Pro
• 32 bit, 768 kHz, DSD 512
• 3.5 mm and 4.4 mm headphone connection
• Double-skin structure

Discrete headphone amplifier with transistors – for detailed music reproduction
Unlike most dongles that use integrated amplifier chips with limited adjustment options, Aune has tested over a hundred combinations of transistors, resistors, and capacitors to achieve its vision of sound quality. The result is a DAC with 16 transistors in a 4-way headphone amplifier that delivers exactly the sound Aune strives for – detailed, nuanced, and powerful.

Sabre ESS DAC chip – high-resolution audio
Yuki SE is equipped with the ES9280AC Pro DAC chip and supports decoding in master band quality up to 32-bit/768kHz and DSD512. This provides unparalleled precision and detail in your music experience.

Double-layer structure – DAC and amplifier completely separated
The innovative double-layer design completely separates the DAC and the headphone amplifier – one layer for the digital DAC circuit and another for the amplifier circuit. Yuki SE is created with true high-resolution (Hi-Fi) reproduction in mind.

Transform your smartphone or tablet into a Hi-Res player
Connect your smartphone or tablet to Yuki SE via USB and experience a significantly improved sound quality. It's that easy to enjoy Hi-Fi sound anywhere, anytime.

The computer's little Hi-Fi friend – 32-bit/768kHz DSD512 high-resolution decoding
Connect Yuki SE to your computer or laptop via USB – no drivers needed. Experience high-resolution audio with 32-bit/768kHz and DSD512 in a smooth and easy way.

A unique dongle DAC – ±5V boost design
Yuki SE uses several DC-DC power management chips to ensure multi-stage noise reduction and precise voltage regulation. This provides a stable power supply to the balanced 4-way transistor amplifier. Despite its compact size, this unit delivers impressive performance.

Femtosecond clock – rich and refined sound
Yuki SE is equipped with two precise AS318 crystal oscillators that provide stable clock signals to the digital core chips, resulting in particularly natural and refined sound reproduction.

Two headphone outputs – High compatibility
"With its ESS DAC chip, an independent 4-way headphone amplifier with ±5V power supply and balanced 4.4 mm and unbalanced 3.5 mm headphone outputs, the Yuki SE can easily drive various types of headphones."

A window to technology – aesthetic elegance
Yuki SE carries forward Aune's classic design with a transparent window and combines an aluminum structure with an aesthetically pleasing whole. Experience the harmonious fusion of art and technology.

High-performance specifications – the foundation for fine sound
