Compact DAC and headphone amplifier

The BFKK SK02 combines an ESS ES9038Q2M DAC with SGM8262 op-amps in a CNC-machined aluminium chassis. It delivers 1100mW into 32 ohms via the 4.4mm balanced output and drives loads from 16 to 300 ohms. High-resolution support reaches DSD256 and PCM 32bit/384kHz with 120dB SNR and 0.001% THD.

Check your sources and connections

The unit accepts USB-C and optical inputs, so verify that your computer, CD player, TV or projector provides one of these digital outputs. No drivers are required for plug-and-play operation on modern operating systems. Ensure your headphones or IEMs use a 3.5mm or 4.4mm plug to match the available outputs.

Front-panel controls and preamp function

A large multi-function knob handles power, play/pause and volume, while dedicated buttons toggle high/low gain and select the active input. Coloured indicator lights show the current mode and incoming sample rate. The variable line-level output lets the SK02 serve as a preamp for active speakers or a separate power amplifier.

Questions about this item

Does the SK02 come with any cables or do I need to buy USB and optical leads separately?

The SK02 requires no drivers and offers plug-and-play convenience, so you can connect it to a computer, laptop, CD player, TV or projector using standard USB or optical cables you already own.

Should I use the 3.5 mm single-ended or the 4.4 mm balanced output for my headphones?

Use the 4.4 mm balanced jack when your headphones have a matching plug to get up to 1100 mW at 32 ohms; the 3.5 mm single-ended jack covers the same 16–300 ohm impedance range with standard wiring.

What do the 120 dB SNR and 0.001 % THD figures mean for everyday listening?

A 120 dB signal-to-noise ratio and 0.001 % total harmonic distortion give an extremely low noise floor and virtually inaudible distortion, so music sounds clean and detailed even at high volumes.
