What Dartzeel Audio does
Dartzeel Audio is a privately-held Swiss high-end audio manufacturer operated by Cape124 Ltd from Vessy, Geneva, founded by electrical engineer Hervé Delétraz, who began building amplifiers in 1984 and whose first commercial design, the NHB-108, was introduced in 1992. The company designs and hand-builds five core instruments organized into three categories: monoblock and stereo power amplifiers (NHB-468, NHB-108 Model Two), a reference preamplifier (NHB-18NS), and integrated amplifiers (CTH-8550 and the network-enabled LHC-208 with DAC and streaming). Its technology platform is defined by a patented zero-global-negative-feedback circuit topology (five patents across WO, EP, US, and CH jurisdictions), first-in-world PLL-free clock distribution for digital playback, battery power supply on the reference preamp, dual-mono architecture with separate toroidal transformer windings per channel, and proprietary 50-ohm BNC Zeel inputs. Each chassis is milled from solid aluminum blocks with over 80 hours of machining plus equal finishing time, with no discounts offered on direct sales.
Dartzeel sells exclusively through country-level international distributors who appoint approved resellers, while acting as its own exclusive distributor for Switzerland and Liechtenstein and selling direct from Switzerland for uncovered markets. The product range is priced from USD 26,664 (LHC-208 integrated) to over USD 260,700 per pair (NHB-468 monoblocks), with all pricing set by distributors inclusive of country-specific taxes, transport, and logistics. The customer base consists of discerning individual audiophiles, music enthusiasts, and audio professionals prioritizing emotional musical reproduction over measured specifications, with no enterprise contracts, no subscription revenue, and no disclosed financials. The company employs 11-50 people, holds no external institutional investment, and is founder-controlled.

Dartzeel Audio product offering
Product offeringCore offering
darTZeel Audio designs, manufactures, and sells high-end audio amplifiers, preamplifiers, and integrated amplifiers for the audiophile and professional listening markets. The product range includes two monoblock/stereo power amplifiers (NHB-468, NHB-108 Model Two), one reference preamplifier (NHB-18NS), and two integrated amplifiers (CTH-8550 and LHC-208), all built around proprietary circuits that eliminate global negative feedback and are handcrafted in Switzerland.
Product overview
Dartzeel Audio is a Swiss high-end audio instrument manufacturer that develops, manufactures, and markets a portfolio of precision audio amplifiers. The product range comprises five main instruments organized into three categories: power amplifiers (NHB-468 monoblock and NHB-108 Model Two), a preamplifier (NHB-18NS), and integrated amplifiers (CTH-8550 and LHC-208). The NHB series represents the pinnacle of the range with dedicated power amplifiers and a preamplifier designed to work together as a matched system. The CTH-8550 and LHC-208 integrated amplifiers offer similar sonic characteristics in more compact form factors, with the LHC-208 adding modern network streaming and digital-to-analog conversion capabilities. All products share darTZeel's design philosophy of "listen first, measure afterwards" and are engineered without global negative feedback circuits.
