Est. year: 1984
darTZeel Audio SA is a Swiss maker of ultra high-end amplification, founded in 2001 in Geneva by electronic engineer Hervé Delétraz. The roots go back to 1984, when Delétraz designed an amplifier without negative feedback as a student project, and the circuit that became the first product took some 16 years to mature. The company works at small volume, and its gold faceplates with red heatsink fins have made the electronics instantly recognisable.
Range & what it's known for
The current catalogue is compact. Power stages are the NHB-108 model two stereo amplifier and the NHB-468, the preamplifier is the NHB-18NS, and two integrated units, the CTH-8550 and LHC-208, bring the circuitry into single chassis. The NHB-108 model one, first shown in New York in 2002, set the template - no global negative feedback, no switch or contact in the signal path and a single pair of output transistors giving 230 watts into 4 ohms, a design covered by a worldwide patent. The company describes its method as listening first and measuring afterwards.
Who owns it and where it's made
darTZeel is an independent Swiss company led by its founder, Hervé Delétraz, who remains responsible for the circuit designs. The products are made by hand in Geneva, where machining, anodising, assembly and finishing are carried out with an emphasis on taking time over each unit. Output is low, and the brand name itself mixes the founder's surname with nods to ReVox typography and Zener diodes.
The lineup in this catalog
Amplifiers and preamplifiers. Prices start at roughly USD 30,000 for the entry electronics and pass USD 100,000 for the largest power amplifiers.
Who it's for
darTZeel fits owners assembling a cost-no-object system who want electronics built around a feedback-free circuit from a founder-run workshop. The LHC-208 or CTH-8550 integrated units are the natural starting point, while the NHB-18NS preamplifier paired with the NHB-108 model two or the NHB-468 is the path upward. It also suits buyers who value low production numbers and hand assembly as much as the technical approach.
