High-Performance USB DAC & Headphone Amplifier Unmatched Audio Fidelity: This compact desktop device delivers exceptional sound quality, boasting a THD+N as low as 0.0001% (-115dB). The impressive Dynamic Range and Signal-to-Noise Ratio (SNR) reach up to 124dB on the 4.4mm headphone output, ensuring crystal-clear audio reproduction without distortion. Powerful Output for All Headphones: Featuring a robust headphone amplifier with near-zero output impedance, it effortlessly drives a wide range of headphones. It delivers up to 700mW of power at both 16Ω and 32Ω. Even high-impedance headphones up to 600Ω are supported, receiving a dedicated 40mW of clean power. Versatile Connectivity: Equipped with a USB input (asynchronous transmission) and three distinct outputs: a 3.5mm line out, a 3.5mm headphone out, and a balanced 4.4mm headphone out. The 4.4mm balanced output provides higher voltage (5 Vrms) and superior SNR/Dynamic Range (124dB) compared to the standard 3.5mm outputs (2.5 Vrms, 119dB), delivering a more immersive listening experience. Comprehensive Format Support: Supporting 1bit and 16-32bit bit depth, the device decodes PCM up to 768kHz and native DSD up to 11.2896MHz. Its asynchronous USB transmission greatly reduces jitter for precise, pure audio conversion. Wide System Compatibility: Plug-and-play compatibility with Windows 7/8/8.1/10/11, Android, iOS, Mac OS X10.6 and above, and Linux systems. It's a perfect companion for computers, smartphones, and tablets. Usage Scenarios: Ideal for home office, professional music production, high-fidelity listening, and competitive gaming. Easily improves the audio quality of your PC, laptop, or mobile device, making it an excellent choice for audiophiles and music lovers. Competitive Advantage: In its class, it offers a rare combination of high power output (700mW at 32Ω) and superior high-resolution format support in such a compact and lightweight design (165g), making it a highly competitive upgrade over standard audio interfaces.
