FiiO K9 Desktop Balanced DAC and Headphone Amplifier
Experience pure, unadulterated sound. The FiiO K9 is a high-performance desktop DAC and amplifier designed to deliver studio-grade audio to your favorite headphones. Built with a focus on balanced power and low-distortion amplification, the K9 serves as the perfect centerpiece for audiophiles who demand precision and musicality without compromise.
High-Performance Dual DAC Architecture
Dual ES9068AS DAC Chips The K19 features two high-performance ES9068AS DAC chips, handling the left and right channels independently. This ensures a clean, high-resolution signal with an impressive signal-to-noise ratio and incredibly low total harmonic distortion, bringing out the finest nuances in your lossless music collection.
Fully Balanced Circuitry From the DAC stage to the amplification, the K9 maintains a fully balanced design. This architecture significantly reduces internal noise and crosstalk, resulting in a more expansive soundstage and precise instrument placement that places you right in the center of the performance.
Legendary THX Amplification
THX AAA 788+ Technology Power meets purity. The K9 utilizes the renowned THX AAA 788+ amplifier modules, capable of providing an effortless 2000mW of power into 32Ω loads and 780mW into 300Ω. This ensures even the most power-hungry high-impedance headphones are driven with full dynamics and authoritative bass.
Six-Stage Audio Circuit The audio signal travels through a meticulously designed six-stage process, including I/V conversion, LPF, and volume control. This rigorous engineering ensures that every milliwatt of power is delivered with the highest fidelity possible.
