The most powerful amplifiers ever developed by darTZeel.
NHB-468 monoblocks are the most powerful amplifiers ever designed and built by darTZeel. They are the culmination of nine years of research and development.
NHB-468 mono amplifiers retain all the musicality of the original signal. The NHB-468's immense power supply ensures that they can cover the full dynamic range, providing effortless delivery from a few milliwatts through to a whopping kilowatt of power.
