AKM AK4493EQ DAC chips

The K5 Pro is equipped with AKM’s AK4493EQ DAC chips - known for its smooth, pleasant yet detailed sound due to its high signal-to-noise ratio and low distortion. Audio up to 768kHz/32 bit sampling rates and bit-depths are supported as well as native DSD

XMOS USB Audio

We elected to use the XMOS XUF208 microcontroller for its stability, powerful functionality, and its proven reliability.

Utterly precise volume control

When the NJRC NW1195A analog volume adjustment chip is paired with the combination of the flagship TI TPA6120 op-amp and the OPA1642 JEFT op-amp,the K5 Pro provides wonderfully smooth,yet high resolution sound.

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.

All-aluminum black body

The all-aluminum black body has been painstakingly CNC-machined, anodized, and sandblasted to ensure that the K5 Pro feels robust yet perfectly textured for a great feel in your hands.

Gain switches

With the K5 Pro, you can switch between low ,medium and high gain levels (depending on how much driving power your headphone needs) .

Unique RGB status lights

With the K5 Pro,the RGB light indicator that surrounds the volume knob lights up with different colors,you can quickly identify the current sample rate.

48kHz and Below:Blue light flashing

48kHz and above: Yellow light flashing

DSD: Green light flashing

Getting precise with toggle switches

Both the input selection(USB DAC/SPDIF IN/LINE IN) and gain(Low 0db/Medium+6db/High+10db)so that its easily for you to control your music

Versatility from multiple interfaces

Different connection options for different scenarios: Coaxial/Optical/RCA line-in +6.34mm(1/4 in.) headphone outputs/RCA line-out

Extremely Powerful headphone amplification

With the K5 Pro we have redesigned and further optimized the audio circuit to squeeze out every last drop of potential from the TPA6120, for a total power output of up to 1.5W under a 32ohm load,and up to 20Vpp at 300ohm.

Safe,Secure,and robust external power supply

The K5 Pro uses a DC 15V power supply designed to specifically minimize noise.This effectively suppresse power supply ripple and minimizes power supply crosstal betweek the two major sections of the sircuit,for a more stable and less noisy power that is crucial for outstanding sound for such a precisely-designed high preformance audio architecture.
