NICEHCK NK1 Ultra

The NICEHCK NK1 Ultra is a pocket-sized USB-C DAC/Amp that transforms your phone, tablet, or computer into a high-fidelity audio source. It pairs a trusted CX31993 decoding chip with a powerful SGM8262 operational amplifier, supported by a dedicated LM27762 dual power supply chip, delivering an impressive 122mW of clean power into 32Ω. The audio signal travels through an 8-core single crystal copper silver-plated cable, ensuring minimal signal loss and a wide, dynamic soundstage. Whether you're driving demanding IEMs or high-impedance headphones, the NK1 Ultra provides a pitch-black background and rich, detailed sound.

Professional DAC Chip – CX31993
At the core of the NK1 Ultra is the proven CX31993 Hi-Fi audio decoder chip, known for its native 32-bit processing and support for sampling rates up to 384kHz. It decodes high-resolution audio files with precision, revealing every nuance in your music.

High-Performance Op-Amp – SGM8262
The signal is then amplified by the SGM8262, a high-current operational amplifier that provides excellent linearity and low distortion. This combination delivers an output of 122mW @32Ω, more than enough to drive most in-ear monitors and many full-size headphones with authority.

Dual Power Supply – LM27762
A dedicated LM27762 power management chip ensures a stable, clean power supply to both the DAC and the amplifier stages. This dual-supply design minimizes noise and crosstalk, contributing to the excellent signal-to-noise ratio.

Audiophile-Grade Specifications

SNR (Signal-to-Noise Ratio): 115dB – an exceptionally low noise floor, revealing micro-details and spatial cues.

Dynamic Range: 115dB – capturing both the quietest whispers and the loudest peaks.

THD+N (Total Harmonic Distortion): -98dB – vanishingly low distortion for a pure, uncolored sound signature.

Sampling Rate: Supports up to 32bit/384kHz PCM audio.

Exquisite 8-Core OCC Silver-Plated Cable
The short USB-C cable is not an afterthought. It is crafted from 8-core single crystal copper (OCC) with silver plating, combining copper's natural warmth and body with silver's speed and extension. The cable is durable, tangle-resistant, and ensures a pristine signal path from your device to the DAC.
