TheAune S9c Prois the new generation of headphone amplifier DAC from Aune which took two years to develop and features the features of full clock synchronization, second generation ultra-low jitter PLL core, 10M clock input, specially designed filter modes, Dual-ES9068A, and a completely discrete headphone amplifier whose output power is up to 5W. 

With multiple functions and excellent performance, this desktop DAC/Amp delights the most demanding headphones. Take note!

The second generation of the PLL coreis a great technological advance that took four years. 

The complex and precise algorithm allows you to generate frequencies corresponding to different resolutions. The ultra-low jitter clock source is simultaneously sent to the USB XMOS/SPDIF part and the DAC, generating natural and vivid sound.

Typically, USB XMOS uses two oscillators to generate clock signals. However, the S9c Pro innovatively adopts ultra-low jitter PLL to generate clock signals and thus allows USB XMOS and DAC chip to share the same clock source, resulting in truly high fidelity.

The digital part also adopts clock synchronization technology: it converts the coaxial/AES/optical signals into IIS signals and together with the ultra-low jitter PLL clock signals, they are reshaped, making the pairing with the transport/digital player also genuinely high fidelity.

The Aune S9c Pro uses a fully discrete amplifier circuit which has a fast transient response and a double JEFT (junction field effect transistor) as the input stage of the amplifier circuit which has high impedance and smooth sound; Coupled with the ±15V linear power supply whose output power is as high as 5W, the S9c Pro has a very powerful amplifier that can bring out the potential of your headphones.

The amplifier output voltage curve has been customized, so that the IEMs also move more effectively.

The Bluetooth connection also adopts clock synchronization technology.

The S9c Pro converts the Bluetooth HD module signals into IIS signals and transforms the IIS signals with ultra-low jitter PLL clock signals.

The S9c Pro not only has two ES9068 DAC chips, but also, with PLL technology, makes them work in clock synchronization mode.

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

To achieve better sound, two tuning modes have been specially developed from two PLL modes and filter modes.

In standard mode, the S9c Pro operates in a fast locking, low latency state. The sound is neutral and natural. In pure mode, the high-performance PLL provides more accurate clock signals. In this mode, the performance of the DAC is improved providing a better scene.

The S9c Pro has the excellent PLL core and 10MHz input clock, giving you more space to explore sound.

The S9c Pro uses the special built-in llS differential isolation transmission technology: the IIS signals from USB and the converted llS signals from coaxial/AES/optical are transformed by the PLL core, and the signals are transmitted and received by symmetrical circuit chips.

Thus, the transmission is almost interference-free, pure and clean.

The 50W low-ripple toroidal analog linear transformer, together with the 23900 μF capacitor array, provides great power to the S9c Pro.

The linear power supply has this incomparable sound advantage, giving you rich and charming sound.

The faceplate is clean and simple, and the knob can perform multiple functions.

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