    Two ES9038PRO DAC chips
    Inside the K9 Pro ESS headphone amp are two ES9038PRO DAC chips, specifically designed for maximum performance in desktop-grade equipment. One ES9038PRO chip, with all of its 8 parallel outputs, is used for each channel to achieve richly detailed sound with minimal distortion.
    Pure clean sound for you
    The THX AAA-788+ chips used in the K9 Pro ESS portable DAC provide exemplary details and dynamics no matter if you are using low or high-impedance headphones. The K9 Pro ESS can produce an undistorted 1100mW* under a 300Ω load, and an undistorted 2100mW* under a 32Ω load, 50% higher than the original THX AAA-788 amplifier chips.
    Fast and reliable Hi-Res Bluetooth
    The K9 Pro ESS bluetooth amplifier employs the Qualcomm QCC5124 to handle Bluetooth duties, with support for formats such as LDAC, aptX HD and aptX Adaptive. This chip ensures that Bluetooth connections are both reliable and quick, satisfying both the low latency needs for games/videos and the high bitrate necessary for high-resolution audio.
    Dual femtosecond clocks, precise clock management
    A dual-mode clock management design is utilized for the K9 Pro ESS desktop amps. Under USB and Bluetooth decoding, dual asynchronous femtosecond clocks are used, while under optical and coaxial decoding, automatic PLL clocks are employed. A more precise clock management system makes it easier to handle any kind of source and maintain the maximum quality possible.
    High-performance linear power supply
    Besides the special high-performance linear power supply, the power stabilization and filtering within the audio circuit is also a big contributor to the K9 Pro ESS’s excellent sound. Specifically, in each stage of the audio circuit, ultra-low-noise LDOs are employed for voltage regulation.
    Choose between high, medium, and low gain
    You could choose between high, medium, and low gain with a physical switch to fit exactly your needs when listening to your particular pair of headphones. It means even when listening at low gain with high-sensitivity headphones both dynamic range and musical fidelity remain uncompromised.
    Convenient USB Type-C port
