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 a 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.
