Founded in 2001 by electronic engineer Hervé Delétraz in Geneva, Switzerland, darTZeel emerged from 16 years of amplifier development.

The boutique manufacturer employs around 20 people, crafting high-end amplifiers, preamplifiers, and integrated systems with distinctive gold and red aesthetics. Their product line includes the NHB-468 monoblocks, NHB-18NS preamplifier, CTH-8550 integrated, and LHC-208 streaming DAC.
