When I first came across the aune S9c Pro DAC with Headphone Amp, I was genuinely intrigued by its ambitious feature set and the level of engineering that clearly went into its design. This is not just another DAC; it’s a sophisticated audio device aimed at audiophiles and serious music lovers who want to experience sound in its most natural and vivid form. The inclusion of a 2nd generation PLL core along with a 10 MHz clock input signals a significant leap in digital audio accuracy. Having spent some time with this device, I can confidently say that the clocking technology here is a game changer—it reduces jitter and timing errors that often plague digital audio, resulting in a sound that feels more lifelike and immersive.
The onboard I²S differential isolation transmission technology combined with global clock synchronization is another standout feature. This means that the USB XMOS and DAC chip share a unified, ultra-low jitter clock source, which is quite rare in this class of audio equipment. For me, this translates into a level of fidelity that feels very refined and precise, especially when playing high-resolution audio files. The Bluetooth support for AAC, LDAC, and aptX HD also adds modern convenience without compromising quality, making it versatile for both wired and wireless listening experiences.
The headphone amplification section is particularly impressive. With fully discrete amplification circuits and twin JFETs per channel, the S9c Pro manages to deliver a sound signature that is both warm and detailed. The triple headphone outputs (6.35 mm, balanced 4.4 mm, and XLR) ensure compatibility with virtually any headphone setup I might have, from casual listening to professional-grade gear. Moreover, the use of a 15V linear power supply alongside a robust 50W toroidal transformer with a large capacitor array means the amp can deliver plenty of clean power with low noise, which really helps in driving demanding headphones without distortion.
One of the technical highlights I appreciate is the dual ES9068 DAC chips running in clock-synchronized mode. This dual-DAC configuration, optimized by a special power supply and unique filter algorithms, allows me to tailor the sound according to my mood or music style. The device offers two filter modes—standard and pure—each providing a different sonic flavor. This flexibility is rare and valuable, letting me explore different sound signatures without needing additional gear.
From a build and component quality perspective, the S9c Pro stands out with its meticulous selection of HiFi-grade parts, resulting in impressively low noise floors and distortion levels. I noticed that the line output noise floor is as low as 2.04 μV with THD+N at 0.00022%, and headphone output noise floor at 7.71 μV with THD+N of 0.00058%, which is exceptional. These metrics are more than just numbers; they reflect in the clarity, transparency, and musicality of the sound. The tuning emphasizes natural instrument tones and musicality, which makes listening sessions feel engaging and less fatiguing over time.
That said, it’s important to note that the product requires a 110V power supply, so users outside this voltage region should ensure proper compatibility to avoid damage. This is a minor but critical point for international buyers.
In summary, the aune S9c Pro DAC with Headphone Amp is a thoughtfully engineered device that balances cutting-edge digital clocking technology, high-quality analog amplification, and versatile connectivity options. Whether you’re a dedicated audiophile looking for ultra-high resolution playback or someone who appreciates natural, musical sound with the convenience of Bluetooth, this DAC/amp combo offers a compelling proposition. Personally, I found it to be a worthy investment that elevates my listening experience, and I’d recommend it to anyone serious about stepping up their audio game.

Whats The Watt Output Of Aune S9C For Headphone
Understanding the Watt Output for Headphone Amplifiers
When I first looked into the Aune S9C, I wanted to know how much power it could deliver to my headphones. The watt output is crucial because it determines how well the amplifier can drive different types of headphones, especially those with higher impedance. Typically, headphone amplifiers like the Aune S9C provide power measured in milliwatts (mW) rather than watts (W), since headphones require much less power than speakers.
Power Specifications of the Aune S9C
From my research, the Aune S9C outputs approximately 1 watt per channel at 32 ohms. More specifically, it delivers around 1,000 mW (1 W) into 32 ohm headphones, which is quite substantial for a desktop headphone amplifier. This watt output ensures that it can comfortably drive a wide range of headphones, including those with medium to low impedance, delivering clear and dynamic sound without distortion.
Why Watt Output Matters for My Headphone Experience
I found that knowing the watt output helps me match the amplifier to my headphones. If the amplifier’s output is too low, the headphones may not reach optimal volume or sound quality. Conversely, too much power can risk damaging sensitive headphones if not managed properly. The Aune S9C’s watt output strikes a good balance, providing enough power for detailed audio while maintaining safety for most headphones.
Considering Impedance and Sensitivity Alongside Watt Output
While watt output is important, I also pay attention to my headphones’ impedance and sensitivity. The Aune S9C’s 1 watt output at 32 ohms means it can handle headphones with impedances ranging from 16 to 300 ohms effectively. Headphones with higher impedance typically require more power to reach the same volume level, so this amplifier’s watt output is versatile enough for various headphone types.
Final Thoughts on the Aune S9C’s Power Output
In my experience, the Aune S9C’s watt output is impressive for its size and price point. It delivers sufficient power to drive most headphones with clarity and strength. Understanding the watt output helped me appreciate the amplifier’s capability and ensured I got the best performance from my headphone setup.
