4.1 Clock Synchronization Technology
The S9c Pro features a 2nd generation PLL core, a technological breakthrough that took four years to develop. This complex algorithm enables the output of frequencies corresponding to different resolutions with ultra-low jitter. The clock source is fed to both the USB XMOS and the DAC part simultaneously, resulting in natural and vivid sound. The 10MHz external clock input provides further possibilities for sound exploration.

4.2 IIS Differential Transmission Isolation Technology & Dual DAC Chips
The S9c Pro utilizes a special onboard-IIS differential isolation transmission technology. IIS signals from USB and those converted from coaxial/AES/optical inputs are reshaped by the PLL core and transmitted via symmetrical circuit chips, minimizing interference. Furthermore, the S9c Pro employs two ES9068 DAC chips that work in clock synchronization mode, optimizing their potential for superior audio conversion.

4.3 Fully-Discrete Amplifier with Twin JFET
The S9c Pro features a fully-discrete amplifier circuit with fast transient response. It incorporates twin JFETs (junction field effect transistors) at the input stage, known for their high impedance and mellow sound. Coupled with a +15V linear power supply, the amplifier delivers up to 5W of output power, capable of driving a wide range of headphones and IEMs effectively. The customized amp objętość wyjściowatage curve ensures optimal performance for both headphones and in-ear monitors.
