The Gryphon Diablo 333 is a reference integrated amplifier engineered to combine exceptional power, control and transparency within a single uncompromising chassis. Designed and built in Denmark, its true dual-mono architecture incorporates technologies developed for Gryphon’s flagship Apex power amplifier and Commander preamplifier, including ultra-fast pre-driver transistors and ten high-current output devices per channel.
A massive dual-mono Holmgren transformer and 68,000µF of power-supply capacitance per channel provide exceptional dynamic headroom, allowing the Diablo 333 to deliver 333W per channel into 8 ohms, doubling to 666W into 4 ohms and reaching 1,100W into 2 ohms. Zero global negative feedback, an ultra-short signal path and a 43-step fully balanced relay volume attenuator preserve clarity and musical expression, while optional PS-3 phono and DAC-3 digital modules allow the amplifier to form the heart of an exceptionally capable high-end system.
