Manufactory for handcrafted tube amplifiers
audioCulture (dimari Technologies GmbH) is a tube manufactory founded in Kassel in 2018 that produces handcrafted tube amplifiers for analog music playback. The product range includes the phono preamplifier “The Phono”, the tube integrated amplifier “The Universal” and “The Magnum” with four power tubes. Each unit is manufactured only after customer order as an individual one-off, including desired RAL paint finish and optional Bluetooth 5.0 extension. The value creation at the Kassel manufactory includes CNC machining and 3D printing of proprietary components (device feet, brackets, acrylic elements), assembly, soldering, measurement and quality control; raw enclosures made of 3 mm sheet steel are painted externally, and transformers and power supplies are manufactured by PIKATRON to audioCulture specifications. Materials include sheet steel, solid copper (RCA sockets), Teflon circuit boards and nanocrystalline transformer cores. Customers are enthusiasts of analog music playback and the high-end HiFi industry; distribution is via partners such as AES Kassel and Musikkammer Willich as well as online.
