Aune S18 EVO - D/A converter
Aune S18 EVO is a reference-class DAC centered around its clocking. Two AKM AK4497 chips are controlled by an external PLL that serves as a shared clock reference, with a mirrored circuit layout and matched components for precise coordination between the left and right channels. The soundstage remains coherent and reproduces the concert hall’s spatial character without sacrificing clarity.
At the heart of the design is a third-generation fully synchronized PLL. It dynamically identifies and eliminates deviations between the reference clock and feedback clock, reducing jitter to the femtosecond level. A global clock synchronization architecture ensures that the entire signal path, from input to output, is based on the same time reference.
All digital inputs benefit from this design. AES, optical, and coaxial inputs are cleaned up through digital synchronization and a low-jitter PLL before the signal is passed to the DAC via the IIS interface. The USB input with XMOS and Aune’s proprietary drivers receives a clock signal of the highest caliber. Bluetooth is also cleaned up via Aune’s proprietary Bluetooth-to-IIS path with PLL clock synchronization, removing the jitter that would otherwise appear as distortion during wireless transmission.
Two custom filter modes give you a choice: a natural mode that does not fatigue the ears, or a smoother and more structured mode. The minimalist, arched front panel is complemented by the solid-aluminum RC1 remote control.
