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 384 kHz and native DSD256 audio. And given its current scarcity, it is definitely a chip many are eager to experience.

Listen to true beauty

The THX AAA 788+ used in the K9 Pro provide exemplary details and dynamics no matter if you are using low or high-impedance headphones. 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.

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 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.

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.
