Aune A17 - Headphone amplifier
Aune A17 is a flagship-class, fully discrete Class A headphone amplifier that also functions as a preamplifier. With a split power supply, precision volume control, and substantial power reserves, it drives everything from sensitive in-ear headphones to the most demanding over-ear models, with stable operation even during long listening sessions.
The input stage is built around twin JFET transistors that provide a natural, warm character reminiscent of tube amplifiers. Two current modes and four gain stages, combined with a 99-step R2R volume control (JRC MUSES72323), allow the drive to be precisely fine-tuned to your headphones. The output stage has three pairs of power transistors in parallel per channel, lowering the output impedance and improving both transient response and bass control.
The power supply is divided into high- and low-voltage sections: the preamp is powered by ±20 V for generous dynamic headroom, while the power amp runs at ±15 V for better thermal balance. The analog section is powered by a 100 W toroidal transformer with an 80,000 µF capacitor bank, while the digital control has a completely separate power supply with digital isolators to prevent interference. Everything is housed in a robust aluminum chassis with multilayer heatsinks for even heat distribution.
The connection panel features 4-pin XLR, 6.35 mm, and 4.4 mm headphone outputs, as well as both RCA and XLR inputs and outputs, making the A17 equally suitable as a dedicated headphone amplifier or as a preamplifier in a speaker system. All functions are controlled with dedicated buttons and mirrored on the included aluminum remote control.
