• [2nd gen of PLL core 10 MHz Clock Input] The 2nd gen of PLL core is a tech breakthrough that took 4 years. It makes the sound more natural and vivid. | Clock is the core and source of the whole digital circuit. The S9c Pro has the excellent PLL core and the 10 M clock input, giving you more room of sound exploration. (Recommended audio clocks: aune S1c /aune SC1/aune XC1)
• [Onboard-llS Differential Isolation Transmission Technology | Global Clock Sync Tech] Usually USB XMOS uses 2 oscillators to generate clock signals. The S9c Pro, however, innovatively adopts the ultra-low-jitter PLL to output clock signals, so the USB XMOS and the DAC chip can share the same clock source; The digital and Bluetooth part convert the signals to IIS signals, and together with the ultra-low-jitter PLL clock signals gets reshaped. The global closk sync brings genuinely high fidelity
• [Fully-Discrete & Twin JFET] Headphone jacks: 6.35 mm/balanced 4.4/XLR, compatible with all kinds of headphones; Fully-discrete amp circuit, fast transient response; twin JFET (junction field effect transistor) per channel, high impedance, mellow sound. 15 v linear power supply, output power as high as 5 W; 50 W toroidal low-ripple analog linear transformer 23900 F capacitor array provides big power. The linear power supply has great sound advantage, giving you the charming rich sound
• [Dual-DAC-Chip | Specially designed filter modes] 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. | To pursue better sound, instead of using the default filters, we specially designed the filter modes with our own algorithm. Mode 1 - standard mode; Mode 2 - pure mode. Enjoy the two different tastes
• [Rigorous HiFi Component Selection | High-Spec | Aesthetic tuning] The components are high-quality and carefully selected. Everything is aimed at good sound. | Line output noise floor as low as 2.04 V, THD N:0.00022%. Headphone output noise floor 7.71 V, THD N:0.00058% (1.78 Vrms /1 KHz 0 dB). Excellent hardware performance is the basis of excellent sound. | The tuning is based on real instrument sounds and music pieces referencing, leading to the signature that is natural and full of musicality
