SKU CH-W5AP-R0Z7B

Combines a dual-DAC converter and headphone amplifier with 32-bit/768 kHz and DSD512 support plus 10 MHz clock input

  • More natural sound from second-generation PLL core
  • 10 MHz clock input expands digital timing precision
  • Global clock sync aligns USB and DAC timing
  • Twin JFET per channel delivers mellow, high-impedance output
  • 35 mm, 4.4 mm and XLR jacks fit all headphones

Dual DAC Headphone Amp for Desktop Audio

The Aune Audio S9c Pro combines a digital-to-analogue converter and a headphone amplifier in a single desktop unit. It targets listeners who want a high-resolution front end for PC, speaker or home-audio systems. The device accepts USB input and provides three headphone outputs for a wide range of headphones.

Second-Generation PLL Core With 10 MHz Clock Sync

A second-generation PLL core developed over four years supplies an ultra-low-jitter clock that both the USB XMOS and dual DAC chips share. Global clock synchronisation reshapes I²S signals for lower distortion during extended listening sessions. A 10 MHz external clock input allows connection of a dedicated master clock for further jitter reduction.

Three Headphone Outputs and 15 V Linear Supply

The front panel offers 6.35 mm single-ended, 4.4 mm balanced and XLR balanced jacks so most headphones plug in without adapters. A fully discrete amplifier stage uses twin JFETs per channel and a 15 V linear power supply fed by a 50 W toroidal transformer. No driver installation is required on modern operating systems.

Questions about this item

How much power does the S9c Pro draw when running continuously?

The unit uses a 15 V linear power supply fed by a 50 W toroidal transformer, so idle and full-load draw stay within that 50 W envelope.

Which headphone connectors must I already own cables for to use every output?

You need cables terminated in 6.35 mm single-ended, 4.4 mm balanced or XLR balanced plugs to match the three front-panel jacks.

Will the 10 MHz clock input work with the external clock I already use?

The 10 MHz clock input is designed for external master clocks such as the aune S1c, SC1 or XC1; other 10 MHz references with compatible signal levels can also be used.
