Q-tron's OTL amplifiers do not use conventional output transformers and deliver ultra clear and expansive sound. The clarity of the bass and treble is especially noticeable, providing a sound quality that is distinctly different from conventional tube and transistor amplifiers. the sound quality has a warmth comparable to that of a SET amplifier, yet is not tiring.
Q-tron Audio was founded in Sweden in 1976 by Hans Beijner, who worked in electronic circuit design and product management at Ericsson, and his brother Ulf. Over the years, they have developed and manufactured sophisticated electronic equipment for the Swedish military and industry, but their deep interest in tube amplifiers led them to design an OTL amplifier using 6C33C tubes, and in 2000 they completed their first product. The performance has been further enhanced by adding distortion correction and noise reduction technologies.
