Until recently, integrated amplifiers only achieved distinction despite trade-offs in design.
Most integrated amplifiers have been built under budget and pricing constraints that leave little room for high performance. That's why darTZeel is proud to present the CTH-8550, the first integrated amplifier without compromise.

With its dual-mono architecture, 50-ohm Zeel inputs, optional high-quality phono stages and remarkable versatility, the darTZeel CTH-8550 is the integrated amplifier of choice for audio enthusiasts.

CTH-8550: at the heart of the music
With up to nine analogue inputs for RCA, XLR and Zeel 50-ohm cables, all sources including turntables are accommodated. Boasting ample power reserve capacity, a wide range of functional features and unrivalled ease of use, the CTH-8550 is the most complete integrated amplifier in its field.

Sound at your fingertips
The remote control is machined and milled from pure aluminium ingot, offering premium build quality and technology to enhance the user experience.

Style and functional features
The darTZeel CTH-8550 is equipped with a plasma control panel, offering excellent contrast when viewed from any angle. A range of menus allows you to individually configure all settings for each input source.

Ease of use
Volume control is handled by an optical encoder notched magnetically, for unrivalled touch and precision. Round steel buttons add to the unit's appeal.

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.
