AUNE S17 Pro: Fully-Discrete Class-A Headphone Amplifier

Discover a New Dimension of Sound

The AUNE S17 Pro marks a breakthrough in headphone amplification, boasting fully-discrete Class-A architecture that delivers a rich, tube-like sound experience. With twin JFET technology, this amplifier achieves high input impedance, ensuring a mellow and resonant audio profile reminiscent of vacuum tubes.

Powerful Performance

Equipped with two transistors per channel, the S17 Pro reaches an impressive 7.5W output, effortlessly driving a diverse range of headphones and IEMs. The R2R electronic volume chip, paired with dedicated op-amps, brings precision to the 4-way balanced volume control, offering remarkable channel balance, wide soundstage, and accurate positioning.

Innovative Display and Control

The UI of the S17 Pro adopts a dual-color scheme, making it easy to monitor current levels and temperature. With two gain levels, this amplifier adapts to various headphones, ensuring optimal performance for both IEMs and high-power headphones.

Stable Class-A Operation

Designed for stability, the S17 Pro employs a complex cooler structure to manage the heat generated by the Class-A transistors. This three-dimensional cooling system guarantees consistent performance and durability.

High-Quality Components

The S17 Pro is crafted with rigorously selected components, including high-quality HiFi electrolytic capacitors, ceramic capacitors, and organic thin-film capacitors. The result is an immersive audio experience that prioritizes purity and authenticity.

User-Friendly Design

With a minimalist front plate featuring a multi-function knob, the S17 Pro ensures ease of use. The all-aluminum remote adds convenience to the control experience. Multiple connectivity options, including headphone outputs, preamp outputs, and line inputs, cater to diverse scenarios.

Arc-Shaped Aesthetics

Featuring an arc-shaped design, the S17 Pro blends classic aesthetics with simplicity. This design philosophy extends to every aspect, ensuring that your auditory and visual senses are equally delighted.

High-Spec Performance

Boasting a low-ripple toroidal transformer and a 19200uF capacitor array, the S17 Pro delivers powerful and rich-sounding audio. With headphone amp output specs of 6uV and THD+N at 0.00038%, this amplifier sets a high standard for hardware performance.

Aesthetic Tuning

The S17 Pro's tuning is a meticulous process based on real instrument sounds and musical references, resulting in a signature sound that is natural, dynamic, and full of musicality.

Really good amp

Compared to thx 789 aune amp really made the vocalist and guitars sound natural. Has more punch and 3d soundstage. Made my hd660s headphones rise on a new level. Treble is a little bit less, doesn't lose any detail though.
