darTZeel NHB-468
Power, elegance and grace.
darTZeel's NHB-468 monoblock amplifiers represent the pinnacle of our 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.

One man’s passion
From a very early age, Hervé Delétraz has been passionate about musical reproduction.
In 1984, he earned his degree in electrical engineering from the École d’Ingénieurs de Genève, for which he built his first audio amplifier.
Today, darTZeel amplifiers are renowned worldwide, producing sound output with dynamic range on a par with a live concert experience.

Listen first, measure afterwards.

This is our guiding principle when developing products. Like Goethe, we believe that what can be measured is not paramount and that what is most important – in terms of emotions – cannot be measured. Theories of physics will never explain how the beauty of music can have such a profound effect on us. When it comes to music, only humans should be the judge.

When we listen to a darTZeel prototype, the question we ask ourselves is: “does this bring us to the heart of the music?” If the answer is not a resounding “Yes”, the amplifier does not enter production.

We take pride in generating this emotion, and it is our passion that has inspired everything we do from the very beginning.

We could of course expertly talk you through the detailed specifications, offering a plethora of measurements and graphs. However, when all’s said and done, we believe that listening pleasure is what matters most. For those of you who simply love music, we strongly recommend paying a visit to your local dealer to try out our range.
