Ultra High Power Output
The Ariadne delivers an impressive 32Vrms output and 90Vpp, providing 20W per channel at 32Ω and 1.7W at 600Ω. Its powerful driving capability can handle even the most demanding 600Ω headphones, surpassing the output of a typical 250W power amplifier.
Low Noise Floor, High Signal-to-Noise Ratio, Large Dynamic Range
With an exceptionally low noise floor of only 10uVrms (A-weighted) and a signal-to-noise ratio of up to 130dB, the Ariadne ensures a clean and immersive audio experience. Its dynamic range, also reaching 130dB (A-weighted), allows for rich and detailed sound reproduction.
 
Low Distortion
The Ariadne boasts a total harmonic distortion (THD+N) as low as 0.001% (8Vrms, 600Ω, A-weighted), significantly outperforming typical headphone amplifiers. This low distortion ensures accurate sound with minimal coloration.
Kunlun Architecture
Most headphone amplifiers use a simple amplification + current boosting structure, which can be divided into two parts: the first part amplifies the signal voltage for high-impedance headphones, and the second part increases the current for low-impedance headphones. The overall structural distortion is the sum of these two components.High-performance devices incorporate nested feedback for further distortion reduction. Due to higher distortion levels common in high-power devices, stronger feedback is needed to control distortion. Therefore, we have adopted the very complex Kunlun Architecture to maintain circuit stability and successfully reduce the THD+N to 0.001% in single-ended mode—far lower than most single-ended amplifiers, achieving high-spec headphone amp distortion levels. We have named this technology "Kunlun Architecture."
Versatile Gain Settings
The Ariadne offers three gain settings—Low, Medium, and High—to cater to a wide range of headphones and earphones. Whether you have sensitive in-ear monitors or high-impedance over-ear headphones, the Ariadne can deliver optimal performance.
Powerful Preamplifier
The integrated preamplifier in the Ariadne enhances your audio system with superior detail resolution, broader dynamic range, and a captivating musical experience. It underscores the critical role of a preamplifier in shaping the tone and driving the power amplifier, making it an essential component for audiophiles.
Comprehensive Connectivity
Equipped with multiple input and output options, including 3.5mm, 4.4mm, 6.35mm, 4-pin balanced, RCA, and XLR (customizable), the Ariadne is versatile and compatible with various audio setups.
