Product description
As aune's new generation of fully discrete Class A headphone amplifiers, the S17 Pro has the power and sound quality. 2 current levels to choose from (50mA/100mA class A idle current), with maximum output power as high as 7.5W.
The S17 Pro has a 50W Toroidal Transformer with a low noise floor + 19200μF large capacitor bank that offers a proper power reserve.
It is a high-performance headphone amplifier with nice sound and high output power.

Pairs well with the Aune S10N Music Streamer with built-in Saber 9038Q2M DAC.


  • Class A headphone amplifier 
  • 3 connections for headphones
  • Discrete components
  • Completely symmetrical structure
  • R2R volume control
  • 50 Watt linear toroidal transformer
  • Aluminum remote control

Twin JFETs provide a tube-like sound.
JFET has high input impedance and full and smooth sound reminiscent of a tube amplifier.
As for the S17 Pro, it's not just a JFET. They are dual JFETs, whose temperature rises are the same, the performance is the same, and the midpoint voltage is stable. It is the ideal input transistor for an audiophile headphone amplifier.

Two gain levels
Push your headphones and IEMs to their full potential.
The S17 Pro has two levels of amplification. The low gain takes advantage of the class-A amplifier's feature that the transistors always work in the linear range, to drive the IEMs well and properly, while the high gain is as high as 7.5W and thus can drive demanding headphones.

Complex radiator structure
The class-A amplifier's transistors create a lot of heat and a complex three-dimensional structure has been created where the heatsink on the transistor + the heating plate at the bottom + chassis form a complete cooling system.

Aluminum multifunction button and remote control
The front of the S17 Pro is clean and simple, and with the one multifunction knob you can adjust power, gain and volume.
The well-designed all-aluminium remote control makes control even easier.

Multi connection
S17 Pro has 3 headphone outputs, 2 groups of preamplifier outputs and 2 line inputs, satisfying your needs in different scenarios.
