Aune S18 EVO is a reference DAC where clocking takes center stage. Two AKM AK4497 chips are driven by an external PLL as a shared clock reference, with a mirrored circuit layout and matched components for precise coordination between the left and right channels. The result is a cohesive soundstage that reproduces the concert hall’s sense of space without sacrificing focus.
At its core is third-generation fully synchronized PLL technology. It dynamically detects and eliminates deviations between the reference clock and feedback clock, reducing jitter to the femtosecond level. A global clock synchronization architecture maintains a unified time base throughout the entire signal path, from input to output.
All digital inputs benefit from this. AES, optical, and coaxial inputs are cleaned up with digital synchronization and a low-jitter PLL, then fed into the DAC via the IIS interface. The USB input with XMOS and Aune’s own drivers receives a superior clock signal. Bluetooth is also reconditioned via Aune’s own Bluetooth-to-IIS path with PLL clock synchronization, eliminating the jitter that would otherwise be heard as distortion during wireless transmission.
Two custom filter modes give you a choice: one natural and fatigue-free, or one smoother and more structured. The minimalist arched front panel is complemented by the solid aluminum RC1 remote control.
