hARt Lab
ActiveOverview
hARt Lab is a Greek high-end audio manufacturer based in Chalandri, specializing exclusively in amplifiers including preamplifiers, power amplifiers, and integrated models.36 The company employs hybrid topologies combining valves and MOSFETs to achieve tube-like sound without conventional tube compromises, developed by a team of audiophile engineers with extensive electronics experience.14 It has participated in events like High End Munich in 2022 and 2023, distributed in the UK by AirT Audio.345
History
hARt Lab was founded in 2018 by Nondas (full name not specified), Nikos, and Kostas, who are audiophile engineers with prior experience in renewable energy and electronics design.1 The brand's core amplifier circuit was developed and tested over 15 years by Nondas, drawing from his 30+ years repairing high-end audio devices and work on reliable electronics for harsh environments like nuclear reactors.1 The team transitioned from hobby projects to commercial production of innovative hybrid amplifiers.16
