Boost your computer's sound

Finest componets for maximum potential

The combination of high-performance AKM AK4452 DAC with low-distortion op-amps OPA926x2 and professional-grade LPF TI OPA1612 make up for a outstanding performance.

Modern USB Type-C input interface

The USB Type-C ensures a more reliable and stable connection. Moreover, the K3 implements overvoltage protection (OVP) and a double-filter circuit to ensure power supply stability.

Two modes of USB audio

In high-performance applications, you can use the 2.0 mode to enjoy up to 384kHz/DSD 256 decoding; For certain situations, you can use the 1.0 mode to enjoy up to 96kHz/24-bit PCM audio without needing any drivers.

ADC volume control

The use of ADC volume control can not only eliminate channel volume imbalances, but also allows the user to smoothly adjust the volume to a more accurate and finer degree to boost headphones of all kinds of sensitivity for a variety of listening needs.

Versatility from multiple interfaces

Different connection options for different scenarios: 3.5mm single-ended and 2.5mm balanced headphone jacks + 3.5mm line out + Coaxial and Optical digital outs.

All-aluminum black body

The all-aluminum black body has been painstakingly CNC-machined, anodized, and sandblasted to ensure that the K3 feels robust yet perfectly textured for a great feel in your hands.
