Fosi Audio SK02 Desktop DAC Headphone Amplifier

Compact yet powerful, the SK02 employs a minimalist and stylish design language. Despite its small size, it boasts mighty features. It supports DSD256 and PCM 32bit/384kHz high-resolution decoding, along with 3.5mm single-ended and 4.4mm balanced headphone outputs. Its robust power can easily drive a wide range of headphones and IEMs with an impedance range of 16-300 ohms.

It features a high-end ESS SABRE ES9038Q2M DAC and SGM8262 op-amps. Its excellent circuit design ensures superior parameters with a SNR as high as 120dB, a low noise floor of only 3.7μV, and an incredibly low THD of 0.001%. The 4.4mm balanced output power reaches an impressive 1100mW at 32 Ohms. The exceptional high-resolution capability and pure sound quality make every listening experience an extraordinary sensory journey.

The user friendly design requires no drivers and offers plug-and-play convenience. It integrates a big multi-functional control knob, allowing easy access to power on/off, play/pause, and volume adjustments. The unit features quick-switch buttons for high/low gain and input modes. Additionally, its colourful indicator lights enable effortless identification of the current working mode and the song's sampling rate.

The SK02 has USB and optical inputs, widely applicable for decoding with computers, laptops, CD players, TVs, and projectors. Not only can it function as a headphone amplifier, but it can also serve as a preamp, pairing with active speakers or an amplifier like Fosi Audio V3, ZA3, TB10D amp, and passive speakers to form a desktop listening or home audio system.

Exquisite and durable, the SK02 is crafted from a single piece of aluminium alloy using CNC machining and a delicate sandblasting process. This not only gives it an exquisite appearance but also ensures lasting durability. In addition, Fosi Audio provides a 24-month worry-free warranty and responsive customer service to all users.

Why Choose The Fosi Audio SK02?

The Fosi Audio SK02 Desktop DAC Headphone Amplifier is one of those compact little units that punches well above its weight, wrapping serious audiophile chops in a slick, minimalist aluminium shell. Under the hood it’s running an ESS SABRE ES9038Q2M DAC with SGM8262 op-amps, decoding up to DSD256 and PCM 32-bit/384kHz with a vanishingly low 0.001% THD, 120dB SNR and a whisper-quiet 3.7μV noise floor — which basically means your music comes through clean, detailed and gloriously unfiltered.

In daily use it’s refreshingly fuss-free: true plug-and-play, a satisfyingly chunky multi-function knob, quick gain and input switches, and smart indicator lights that make it feel intuitive rather than techy.
