Tubes, Valves - Thermionic Emissions

Azzolina Audio was born in pursuit of the high fidelity music reproduction using tubes and horns. The term "natural motion" was used in thermionic texts books at the inception of the triode technology and we have brought this back to modern amplifiers. Direct heated triodes, with individually designed transformers, and elegant bias techniques sets the stage for real musical drama.
