FiiO K9 Pro Flagship Desktop DAC with headphone amplifier
Something you will want to keep
The K9 Pro, conceived as a flagship from the very beginning, is designed to be uncompromising as both an amp and a DAC. Its outstanding performance will ensure you want to leave a spot for the K9 Pro in your collection of audio gear.
The strength to always triumph Legendary AK4499
The K9 Pro is equipped with the legendary AKM AK4499, renowned in the audio Industry for its exceptional performance and unparalleled decoding capabilities, supporting up to 394 kHz and native DSD256 audio. And given its current scarcity, it is definitely a chip many are eager to experience.
THX AAA amplifier technology
The THX AAA 788, chips used in the K9 Pro provide exemplary details and dynamics no matter it you are using low or high-impedance eadphones. The K9 Pro can output up to 46Vpp transients when driving high-impedance loads, and up to an undistorted 2W* when pushing low-impedance loads. Compared to the original, the output power of the K9 Pro has increased by more than 50% with higher heat dissipation efficiency.

Clearly partitioned for smooth signal transmission
The PCB of the K9 Pro uses a partitioned layout, wherein not only the power supply and signals are separated, but the analog signal loop is also put in an independent section, guaranteeing the integrity of the audio signal being processed.
LDOs for each audio circuit stage
While the special high-performance transformer is important to the K9 Pro's phenomenal sound, special attention was also paid to the power stabilization and filtering within the audio circuit. In each stage of the audio circuit, ultra-low-noise LDOs are employed for voltage regulation. No expense was spared in ensuring clean power supply, with the K9 Pro in total having a substantial amount of 20 LDOs!
Dual femtosecond clocks of excellence
The newest generation of XMOS chips supports dual-mode clock management technology. 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.
Lossless MQA decoding
The K9 Pro supports the unfolding of MQA tracks, allowing you to listen to high-resolution audio files that are not only reasonably sized, but also retain master-level sound quality that brings you directly into the recording studio.
Fast and reliable hi-res Bluetooth
The K9 Pro employs the QuaIcomm 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. Bluetooth format support: AAC/SBC/aptX/aptX LL/aptX HD/LDAC/aptX adaptive.
Essentiality of volume adjustment
Adjusting the volume may look like a simple concept, but a good execution of it is crucial to an excellent audio experience. The ADC curve reconstruction method of volume adjustment used In the K9 Pro effectively minimizes any left-right channel volume imbalance and noise. It also results In a smooth change of volume across all levels. This attention paid to the simple process of volume adjustment is just another layer to making sure you truly savor your music with the K9 Pro.
Headphones come alive with a good source
Switch between high, medium, and low gain to fit exactly your needs when listening to your particular pair of headphones. Thanks to the pure hardware gain circuit, even when listening at low gain with high-sensitivity headphones both dynamic range and musical fidelity remain uncompromised.
Perfection exemplified
The simple, yet elegant all-aluminum black exterior is anodized and finely sandblasted with painstaking craftsmanship for a textured, luxurious feel. Controls are clearly and intuitively laid out to make operating the device as smooth as possible. Rest assured, the K9 Pro is the very definition of a reliable and loyal music partner in your home.
Lighting up the mood
The stainless-steel volume knob blends seamlessly with the aluminum alloy front panel to give a luxurious experience while controlling your music. The RGB indicator lights surrounding the volume knob can light up differently depending on the currently playing sampling rate.
Switch quickly to your music
Easy-to-use metal switches are used for controlling input selection and gain level to help you easily and quickly switch to your desired method of listening.
