Margules is a Mexican family audio company based in Mexico City, founded in 1925 by Jacob Margules, a European engineer who settled in Mexico. It is now run by the fourth generation of the family and its main products are tube amplifiers, above all the U-280, which has been made in evolving versions since 1990. The company also builds loudspeakers, turntables, phono components and music servers.
Range & what it's known for
The U-280 was presented as the first servo-controlled full class A tube amplifier that needs no bias adjustment. Its active servo bias tracks the input signal so the output tubes run in class A without saturating the output transformer. As a stereo amplifier it delivers 80 W per channel into 8 ohms in ultra-linear mode and 40 W in triode mode, and anniversary editions such as the U280-SC 25th and 30th have followed. The SF220 preamplifier, offered in a 20th anniversary version, pairs with it. Newer products include the Magenta Music Server from 2023 and the Orpheo Century loudspeakers from 2024, and since 2020 the company has applied its own design approach called ANA.
Who owns it and where it's made
Margules is privately held by the founding family. Alejandro Margules, the second generation, ran the Tel Rad and Marvox businesses, and his son Julian Margules launched the Magenta line in 1981 and designed the U-280. The company has offices on Morelia street in the Roma Norte district of Mexico City and moved production to a larger factory in 2018 to meet demand, so design and manufacture both stay in Mexico.
The lineup in this catalog
Amplifiers and preamplifiers. A Margules component costs from roughly USD 3,000 to above USD 15,000.
Who it's for
Margules makes sense for an owner after a class A tube amplifier without regular bias checks who also likes to try different output tubes. The U-280 power amplifier with an SF220 preamplifier forms the core system, and owners can extend it later with Margules turntables, phono stages or the Magenta server from the same maker.
