DarTZeel NHB-468 Power Amplifier
Power, elegance and grace. DarTZeel’s NHB-468 monoblock amplifiers represent the pinnacle of their range. Travel faster than the speed of thought with the NHB-468.
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’ 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.
Musical escape without compromise
We like to say that the NHB-468s are faster than the speed of thought.
State of the art
The NHB-468 highlights more than ever darTZeel’s considerable expertise: a generous power supply, a shielded transformer suspended by a dedicated platform, a chassis built from specially extruded aluminium components in line with darTZeel specifications, toughened glass side panels with a sanded logo, and a cooling unit finished and polished by hand.
Swiss precision
Every detail makes the darTZeel NHB-468 an exceptional amplifier. The casing alone required more than 80 hours of machining, with the same amount of time allocated to finishing, anodising and final assembly. The NHB-468’s specially developed audio circuits offer unparalleled musical output, from 0.001 to 1,000 watts and beyond.
Listening to music without limits is now a reality.
