  • Aune S17 Pro Headphone Amp


    Aune S17 Pro Headphone Amp. Fully discrete design, Class-A fully balanced headphone amp.

    *In stock, free shipping

    High power output with extremely accurate R2R volume control for compatibility with a wide variety of headphones. Experience a rich, tube like audio quality.

    • 2 levels of current to select from
    • 3 gain levels
    • Up to 7.5 watts output
    • XLR / 6.35mm / 4.4mm headphone outputs
    • XLR line in / out

    The display changes colour based on the current level chosen - blue for low & red for high, making it easy to see which mode the amp is in.

     As Aune’s new generation of fully-discrete class-A headphone amp, the S17 Pro has the features of twin JFET & R2R volume control.  JFET has high input impedance and rich and mellow sound like the vacuum tube. As for the S17 Pro, it’s not just JFET. It’s TWIN JFET, whose temperature rises are the same, performances are the same, and the mid-point voltage is stable. It is the ideal input transistor of a headphone amp. 

    The S17 Pro final output stage uses two pairs of output transistors in parallel. The whole device has as many as 16 output transistors. Max output is 7.5W. It can drive all kinds of headphones and IEMs with ease.

    The S17 Pro specially designed two levels of class-A current: 50mA/100mA per transistor, and each channel of the S17 Pro has two pairs of transistors in parallel, so the quiescent current of each channel is as high as 100mA/200mA. The sound of a class-A amp is mellow, warm and smooth.

    A class-A amplifier's output transistors remain conducting all the time whether there's an input signal or not, and have the currents equal to the AC peak. The maximum AC signals flow to the load. The open-loop distortion is extremely low. Therefore, it’s regarded as the ideal amplifying circuit design.

    Aune S17 Pro CLASS-A.

    The sound of the class-A amplifier is lush and full of details. Since the transistors perform in their most linear way, the class-A amplifier barely has distortion. The listening experience is excellent.

    Aune S17 Pro uses the R2R electronic volume chip from JRC and the dedicated op-amps to build the 4-way balanced R2R volume control. High control precision, great channel balance, wide soundstage, accurate positioning.

    The class-A amp’s transistors are always working in the linear area, which causes a lot of heat. Aune’s industrial designer built a complex three-dimensional structure, making the heat sink on the transistor + heat plate at the bottom + chassis form a whole cooler system. And the heat goes out through the rear plate heat emission holes. The class-A stability is thus guaranteed.

    The front plate is clean and simplistic, and with the one multi-function knob you can adjust current, gain and volume. Let the listening be pure and easy. The well-designed all-aluminum remote makes the control even more enjoyable.

    Aune S17 Pro has 3 headphone outputs, 2 groups of preamp outputs and 2 line inputs,

      Headphone Bar Aune S17 Pro Headphone Amp Review

      Wow, what an incredible amp

      A stunning amp, all the headphones ive tried with it are noticeable better sounding. More detail, more life , more of everything. This took my ZMF Auteurs from a headphone I really liked to one that I love. The verite are simply superb and my Radiance have never sounded better, The bass is just delicious. I love this amp, one of the best purchases Ive ever made.
