Aune S9c Pro Reference

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

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

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

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

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.

Dual DAC Chip

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

The S9c Pro has headphone outputs of single-ended 6.35mm, balanced XLR and 4.4mm, compatible with all kinds of headphones and IEMs.
