Houses Two Transistors Per Channel For High Performance

Aune Audio S17 Pro EVO amplifier uses two pairs of parallel output transistors per channel with 16 transistors to deliver up to 7.5 W to drive any headphones or IEMs with minimal distortion. Its Class A design keeps transistors conductive at all times, ensuring exceptionally low no-load distortion and ideal circuit performance. To manage the heat generated by linear operation, it features an advanced 3D thermal system, combining a transistor heat sink, base plate and housing with rear airflow vents to ensure stable Class A performance. 

Equipped With Two-Stage Class A Current Adjustment

Aune Audio S17 Pro EVO features two-stage Class A current adjustment, allowing the passive current per channel when set at 100mA or 200mA. This design enhances sound quality to deliver soft, warm, and smooth with highly detailed and tonal audio output. 

Features Twin JFET Transistors To Present A Tube Like Sound

Aune Audio S17 Pro EVO features a Twin JFET (Junction Field Effect Transistor) configuration to offer high input impedance with a sound signature reminiscent of tube amplifiers. This configuration ensures consistent temperature, power and stable centre voltage, making it the ideal input transistor for a high-performance headphone amplifier.  

Embeds Hi-End Components For An Uncompromising Sound

Aune Audio S17 Pro Evo houses premium hi-fi electrolytic capacitors, ceramic capacitors, organic thin-film capacitors and communication-grade printed circuit boards. Each element is carefully and precisely selected to deliver exceptional sound.

Precise R2R Volume Stage By JRC With Dual Gain Levels

Aune Audio S17 Pro EVO utilizes an R2R electronic volume chip by JRC with advanced operational amplifiers to create a 4-way balanced R2R volume control system. This design offers high precision, excellent channel balance, a wide soundstage and accurate imaging for an optimal listening experience. The amplifier features two gain settings tailored to different output needs. The low gain can drive IEMs, leveraging the Class A amplifier's linear transistor operation and the high gain delivers up to 7.5 W to effortlessly drive high-power headphones with THD+N up to 0.00024%.

Robust Power Supply For Pure and Powerful Sound

Aune Audio S17 Pro EVO is equipped with a 50W low-ripple toroidal transformer and a 19200μF capacitor array to offer clean and stable power delivery. The independent digital and analogue power supplies eliminate interference to provide powerful and rich sound. 

Versatile Connectivity With An All-New 4-Inch User-Interface

Aune Audio S17 Pro EVO embeds XLR line in, XLR preamp out, RCA line in, RCA preamp out, balanced 4-pin XLR headphone socket, and balanced 4.4mm and 6.3mm single-ended headphone output for versatile connectivity with various audiophile devices. The new user interface employs two colour indicators to display the current mode and temperature.
