Boost your computer's sound

Equipped with an XMOS U30881C10 USB receiver chip, the K3 is capable of decoding up to 384kHz/32 bit PCM and native DSD256.

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.

A tactile audiovisual experience

The volume knob, with 45° notches etched onto its surface and perfectly sized to allow easy one-finger operation. Next to the volume knob is an RGB light that indicates what kind of digital audio is being input to the K3.

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.

Customer Reviews
  1. Very good value DAC!
    Quality
    100%
    I'm just an average consumer looking for good audio, by no means an audiophile but i'm able to tell a good DAC when i hear one. Came from the Audioengine D1 and Fiio E10K. This is an improvement over both. Mids and highs are great with this DAC, i listen to vocals and instrumental music. Provides excellent value over very expensive DACs.
