Fosi Audio SK02 DAC Headphone Amplifier Preamp Support DSD 256 PCM For 3.5MM & 4.4MM Balanced Headphone

Features:

*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 wide range of headphones and IEMs with an impedance range of 16-300 ohms.

*Stunning Performance: 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.

*User-Friendly Design: The SK02 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 colorful indicator lights enable effortless identification of the current working mode and the song's sampling rate.

*Remarkable Versatility: Supports USB and optical input, 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 aluminum 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 pledges to provide a 24-month worry-free warranty and responsive customer service to all users.
