New USB SoundUnleashing the Full Potential of XMOSMost USB DAC circuits on the market follow a conventional design: two crystal oscillators provide clock signals for the XMOS chip. To fully unlock the potential of XMOS in combination with aune’s custom drivers, the S18 EVO uses an ultra-low-jitter PLL to deliver a superior clock signal. This ensures full device synchronization and enables true high-fidelity reproduction.Fully Synchronized IIS Signal PathDirect-to-DAC ArchitectureAES, optical, and coaxial inputs are reconditioned using digital synchronization technology combined with a low-jitter PLL. All signals are then fed into the DAC via the IIS interface—resulting in higher fidelity, more natural reproduction, and authentic sound across all inputs.In-House Bluetooth to IIS + PLL Clock SynchronizationHi-Fi Bluetooth PerformanceConventional Bluetooth signals typically exhibit high jitter, which can lead to audible distortion when sent directly to a DAC. aune uses its proprietary Bluetooth and PLL technology to recondition the digital signal before passing it to the DAC—delivering high-fidelity sound even via Bluetooth.Dual DAC ChipsPrecisely SynchronizedUnlike conventional single-chip or asynchronously clocked DACs, the S18 EVO uses an external PLL as a clock reference for two AK4497 chips. Combined with mirrored circuitry, layout, and components, this ensures precise coordination between left and right channels—recreating the cohesive soundstage of a live concert hall.Custom FiltersMore Choice for Your SoundBuilt-in DAC chip filters are often complex and not easily understood. For the S18 EVO, our engineers have developed two dedicated filter modes: one for natural, fatigue-free listening, and one for a smooth, well-structured sound. Easily tailor your listening experience to your preferences.All-Aluminum Remote ControlSimple & IntuitiveThe minimalist front design, combined with the well-crafted RC1 all-aluminum remote, makes operation effortless—for a relaxed and immersive listening experience.Premium Hi-Fi ComponentsEverything for Sound QualityWe have carefully selected high-end components from leading brands such as Nikon and Panasonic: electrolytic capacitors, ceramic capacitors, organic film capacitors, communication-grade PCBs, and more.
