Key Features
The SK02 features the ESS SABRE ES9038Q2M DAC paired with SGM8262 operational amplifiers to deliver high-resolution audio decoding up to PCM 32-bit/384kHz and DSD256 formats. It supports both 3.5mm single-ended and 4.4mm balanced headphone outputs, capable of driving headphones and in-ear monitors with impedance ranging from 16 to 300 ohms. The balanced output can deliver up to 1100mW of power at 32 ohms, while maintaining a signal-to-noise ratio of up to 120dB, a low noise floor of approximately 3.7μV, and total harmonic distortion as low as 0.001 percent for clean and accurate sound reproduction. The device supports USB and optical inputs and can function as both a headphone amplifier and a preamplifier for use with powered speakers or external amplifiers, allowing it to integrate easily into a desktop or home audio system. The SK02 requires no drivers and operates with simple plug-and-play connectivity, while a large multifunction control knob allows users to adjust volume, power, and playback functions. Additional controls allow switching between high and low gain settings and selecting input modes, while color indicator lights display the active mode and audio sampling rate. The unit is constructed from CNC-machined aluminum alloy with a sandblasted finish for durability and a premium appearance.
