A single-stage discrete gain circuit voiced around the BC109B low-noise silicon transistor.
Shaped for clarity and controlled edge.
Voiced by ear.
Released in limited numbers.
Built once.
Designed to enhance an amplifier without excess — adding presence, definition, and harmonic lift with restraint, while retaining a tight, articulate response.
Each unit is hand-assembled and individually calibrated in Salzburg.
