Aune S9c Pro DAC (Sealed/New)-This DAC Is Brand New And Sealed. Bought for a Friend that can't use it.with Headphone Amp, 10MHz Clock Input, 32bit/768kHz/DSD512/MQA, Dual-DAC Chip, 6.35/XLR/4.4 Jack, PLL/Clock Sync Tech/Twin JFET, for PC/Speaker/Home Audio (Silver)Features:[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 parts convert the signals to IIS signals, and together with the ultra-low-jitter PLL clock signals gets reshaped. The global clock 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. 土15 v linear power supply, output power as high as 5 W; 50 W toroidal low-ripple analog linear transformer + 23900 μF capacitor array provides big power. The linear power supply has great sound advantage, giving you the charming rich sound[Dual-DAC-Chip | Two Tuning 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, we specially developed two tuning modes from two PLL modes and filter modes. 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 μV, THD+N:0.00022%. Headphone output noise floor 7.71 μV, 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
This is a notable all-in-one desktop DAC/amp from aune, and at US$649 it lands above the typical used market for this category. Against your recent comps, it sits well above the median US$397 and even past the US$549 75th percentile, so this reads as ambitious unless the listing includes extras or truly looks untouched.
The appeal is the clean, modern feature set: aune’s S-series gear is generally well-liked for strong measured performance, smooth amplification, and a refined desktop footprint that suits both headphones and speaker-chain duty. “NEW” condition and a current-year unit add some value, but the price still asks a premium, so buyers should verify exactly what’s included and whether warranty transfer is possible.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Aune Audio traces its roots to 2004 in Wuhan, China, where a group of six seasoned audio enthusiasts and DIY experts united under the banner of the influential HIFIDIY.NET community. This online hub, active from 2004 to 2014, fostered a decade of innovative designs and shared passion for high-fidelity sound. Evolving from Wuhan AO LAI ER Technology Co., Ltd. and later Wuhan Aune Acoustics Co., Ltd., the brand emerged as one of China's pioneering dedicated digital audio enterprises, blending engineering expertise with a commitment to quality manufacturing.
The company specializes in a focused lineup of hi-fi components, including desktop DAC/amp combos, headphone amplifiers, digital transports, players, clocks, and headphones. Standouts include the S9c Pro with its dual ES9068A DACs, ultra-low-jitter clock synchronization, and discrete twin-JFET amplification delivering up to 5W. On the headphone front, Aune's AR-series features innovative MLD (Multi-Layer Distributed) diaphragms for enhanced driver performance, alongside ergonomic designs that prioritize measurable fidelity in distortion, noise, and frequency response.
Positioned as a mid-tier contender in the global hi-fi market, Aune earns respect for rational integration of proven technologies, delivering solid performance without extravagant claims. It appeals to discerning buyers seeking value-driven precision over hype, with reliable support like 24-month warranties and EU shipping from Germany. While not a luxury pinnacle, its thoughtful engineering cements a niche for practical, high-quality audio solutions.
