Aune S9c Pro DAC Headphone Amp
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-ES9068A, and the fully-discrete headphone amp whose output power is as high as 5W. It just stands out in every way. 
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.
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!
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.
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.
