NHB-468

Overview

The NHB-468 represents the pinnacle of darTZeels monoblock power amplifier lineup after nine years of R&D. Lauded by audiophiles and reviewers alike, it delivers colossal power reserves with exceptional finessefrom milliwatts to kilowattswhile maintaining complete musicality. It’s Swiss-made precision meets raw sonic emotion, seamlessly blending brutal authority with artwork-like elegance in both design and performance.

Technical Specs

With an open-loop output stage and the unique CP2C circuit, the NHB-468 offers a virtually ideal power-to-current source, ensuring unmatched dynamic responsiveness. It delivers 465 W RMS (550 W peak) into 8 , 625 W (700 W peak) into 4 , and 222 W (300 W peak, software-limited) into 2 , supported by a 750 J suspended power supply. Frequency response stretches from 0.7 Hz to 700 kHz with THD under 1%, temporal distortion eliminated, and signal-to-noise ratio above 115 dB. Its combination of agility, transparency, and power makes it faster than thought.
