Each device from Angstrom Audio is one of a kind, manufactured in their laboratory with the care that is usually reserved for a work of art. From the simplest integrated stereo amplifier of the Stella series, up to the behemoth and exclusive Quantum series, the wiring of each piece is in full view, and realized in strict compliance with the design specifications of Roberto Garlaschi.
