The Gryphon Commander is the company’s flagship reference preamplifier, engineered as an uncompromising expression of Gryphon’s four decades of analogue design experience. Designed and built in Denmark, its true dual-mono architecture employs fully discrete balanced Class A circuitry, zero global negative feedback and complete mechanical separation between the audio and power-supply sections to preserve exceptional transparency, dynamic expression and musical resolution.
A dedicated power-supply chassis contains four custom-made toroidal transformers and 90,000µF of capacitance per channel, with independent linear supplies for the analogue and digital control circuitry. An 85-step relay volume attenuator uses Charcroft Z-Foil ultra-precision resistors, while extensive constrained-layer damping, ultra-low-noise regulation and minimal internal wiring provide an exceptionally quiet and mechanically stable platform for the audio circuitry.
