Aune S9C Pro Dual ES9068AS Fully Balanced Powerful HiFi Lossless Audiophile Desktop Headphone Amplifier


The all-round master

PLL clock synchronization

Fully discrete 5W amp

Dual DAC chip

External clock support


As aune’s new generation of DAC with headphone amp that took 2 years to develop, the S9c Pro has the features of full clock synchronization, the 2nd gen of ultra-low-jitter PLL core, the 10M clock input, the specially designed filter modes with our own algorithm, Dual-ES9068AS, and the fully-discrete headphone amp whose output power is as high as 5W. It just stands out in every way.

Innovations. Real innovations.

PLL phase-locked loop

IIS differential transmission isolation tech

SPDIF-IIS conversion + clock sync

USB clock sync

Special tuning modes design by aune

Bluetooth-IIS conversion + clock sync(Bluetooth version)

10M clock input

Stands out among peers

Toroidal linear transformer: 50W

Twin JFET per channel: 5000mW headphone amp

Capacitor array: 2390μF

Dual ES9068AS work in clock sync mode

Main device weights 3.1kg: 1080 components in total

16 output transistors: 2 pairs for each channel of the amp

2nd Gen of PLL Core, pure, right from the start

The 2nd gen of PLL core is a tech breakthrough that took four years. The complex and precise algorithm enables it to output frequencies corresponding to different resolutions. The ultra-low-jitter clock source is fed to the USB XMOS/SPDIF and the DAC part simultaneously, leading to the natural and vivid sound.

*10kHz-30MHz, jitter 594fs; 3Hz-1MHz jitter 1.216ps

Clock sync tech for the 16-core USB framework master-tape-grade USB decoding

Usually, USB XMOS uses two oscillators to generate clock signals. The S9c Pro, however, innovatively adopts the ultra-low-jitter PLL to output clock signals, and thus allows the USB XMOS and the DAC chip to share the same clock source, which leads to the genuinely high fidelity.

Clock sync tech for digital framework, high fidelity for the pairing with digital transport/player

The digital part also adopts clock synchronization technology - converts the coaxial/AES/optical signals to IIS signals, and together with the ultra-low-jitter PLL clock signals gets reshaped, making the pairing with digital transport/player so genuinely high-fidelity as well.

The fully-discrete amp with twin JFET per channel, powerful and rich-sounding

The S9c Pro uses fully-discrete amp circuit which has fast transient response, and twin JEFT (junction field effect transistor) as the input-stage of the amp circuit which has high impedance and mellow sound; together with the ± 15V linear power supply whose output power is as high as 5W, the S9c Pro has a very powerful amp that can bring out the potential of your headphones. We customized the amp output voltage curve, so not only headphones but also IEMS can be driven just in the right way.

Clock sync tech for Bluetooth, also get “HiFi” with Bluetooth! (Bluetooth Edition Only)

Even the Bluetooth part adopts clock synchronization technology - the S9c Pro converts the signals from the HD Bluetooth module gets to IIS signals, and reshapes the IIS signals with the ultra-low-jitter PLL clock signals. With clock synchronization, Bluetooth can have high fidelity too.

Dual DAC chip and work in clock sync mode

The S9c Pro not only has two ES9068 DAC chips, but also, with the PLL technology, has them work in the mode of clock synchronization. Moreover, we optimized the way of power supply, to bring out the chips' potential.

3 headphone outputs compatible with all kinds of headphones and IEMs

The s9c Pro has headphone outputs of single-ended 6.35mm, balanced XLR and 4.4mm, compatible with all kinds of headphones and IEMs.

Two tuning modes, two different tastes

To pursue better sound, we specially developed two tuning modes from two PLL modes and filter modes with our own algorithm.

MODE 1: standard mode - the S9c Pro works in the state of fast locking and low latency. The sound is neutral and natural.

MODE 2: pure mode - the high-performance PLL provides more precise clock signals. In this mode, the performance of the DAC is improved. Have higher sound density, better soundstage.

10M external clock support, more possibilities of the sound

Clock is the core and source of the whole digital circuit. The S9c Pro has the excellent PLL core and the 10MHz clock input, giving you more room of sound exploration. (Recommend audio clocks: aune S1c / aune SC1 / aune XC1)

IIS differential transmission isolation tech, clean, super clean

The S9c Pro uses the special onboard- IIS differential isolation transmission technology - the IIS signals from USB and the lS signals converted from coaxial/AES/optical, gets reshaped by the PLL core, and the signals are transmitted and received by the symmetrical circuit chips. The transmission is almost free from interference. It’s pure and clean.

50W low- ripple toroidal transformer + 23900μF capacitor array, enjoy the richness

The 50W toroidal low-ripple analog linear transformer, together with the 23900μF capacitor array, provides big power to the S9c Pro. The linear power supply has this unparalleled sound advantage, giving you the charming rich sound.

Multi-function knob & all-aluminum remote easy & fun to use

The front plate is clean and simplistic, and the knob can execute multiple functions. Let the listening be pure and easy.

The well-designed all-aluminum remote makes the control even more enjoyable.

Rigorous HiFi component selection, only for the sound

The components used for the S9c Pro are high-quality ones that are carefully selected, such as the COG and the FK HiFi capacitors, the SMT film decoupling capacitor, the communication-grade PCB, etc. Everything is aimed at good sound.

The beauty of arc and simplicity

The symbolic arc-shape design. Classic, simplistic, aesthetic. Enjoy music with the enjoyable design.

High-spec, the basis of excellent sound

Line output noise floor as low as 2.04μV, THD+N: 0.00022%. Headphone output noise floor 7.71μV, THD+N: 0.00058%(1.78Vrms /1KHz 0dB). Excellent hardware performance is the basis of excellent sound.

Aesthetic tuning

The tuning is based on real instrument sounds and music pieces referencing, leading to the signature that is natural and full of musicality.

Multi-connectivity, headphones, active speakers, devices with line in/preamp in

USB: computer, PAD, smartphone, portable music player OTG

Coaxial/AES/optical: digital transport, streamer, set-top box, portable music player

Bluetooth(Bluetooth edition only): laptop, PAD, smartphone, portable music player
