• Class AB mode provides cleaner, more dynamic, and neutral sound

This flexibility allows users to choose the sound profile that best suits their music.

Powerful Amplification for Versatile Use

With a powerful amplification stage using high performance op amps and buffers, the Nunchaku delivers 525mW per channel at 32 ohms. It can drive most earphones and many headphones with ease.

FPGA Processing for Accurate Signal Control

The built in FPGA system ensures precise signal timing and synchronization. Combined with a femtosecond clock, it reduces jitter and improves overall sound accuracy.

JRC Hardware Volume Control for Better SNR

The hardware volume control allows the DAC to operate at full output while adjusting the signal at the amplification stage. This improves signal to noise ratio and results in a cleaner background.

Advanced Shock Protection for Stable Performance

The Nunchaku features a PORON suspension system to reduce vibration and microphonic effects. This ensures consistent sound quality even when used on the move.
