Aune Audio S9c Pro DAC Headphone Amp Silver

The Aune Audio S9c Pro is a desktop DAC and headphone amplifier combined in one silver chassis. It targets listeners who want a single unit to decode high-resolution digital audio and drive a wide range of headphones. The device accepts USB input and provides three headphone outputs for direct connection. It suits home-audio enthusiasts upgrading from basic computer audio.

32-bit 768 kHz DSD512 MQA decoding

The unit handles PCM up to 32-bit and 768 kHz plus DSD512 and MQA streams, giving ample headroom for modern high-resolution files. A second-generation PLL core and a dedicated 10 MHz clock input reduce jitter and allow an external master clock for tighter timing. Global clock synchronisation aligns the USB interface and dual DAC chips to one ultra-low-jitter source. The linear 15 V supply and 50 W toroidal transformer support sustained output up to 5 W, so demanding headphones stay controlled before the amp reaches its limits.

6.35 mm XLR 4.4 mm jacks twin JFET amp circuit

Three headphone sockets — 6.35 mm single-ended, 4.4 mm balanced and XLR balanced — let you plug in virtually any headphone without adapters. The fully discrete amplifier uses twin JFETs per channel for high input impedance and a mellow tonal character. Onboard I2S differential isolation reshapes the digital signal alongside the PLL clock for cleaner conversion. The package includes the main unit only; external master clocks such as the S1c, SC1 or XC1 are sold separately.

Questions about this item

Will the 10 MHz clock input on the S9c Pro work with my existing aune S1c clock?

Yes, the 10 MHz clock input is designed to accept external clocks such as the aune S1c, SC1 or XC1 for tighter synchronization.

How can I verify the dual-DAC chip is decoding 32-bit 768 kHz or DSD512 correctly after setup?

The front-panel indicator shows the incoming sample rate and format so you can confirm 32-bit 768 kHz or DSD512 playback in real time.

Which cables are included for the 6.35 mm, 4.4 mm and XLR headphone outputs, and what must I buy separately?

The box contains the unit, a power cord and a USB cable; headphone cables for 6.35 mm, 4.4 mm or XLR terminations are not included.
