Diablo 333

About the Diablo 333

The Gryphon Diablo 333 is a flagship integrated amplifier offering 333 watts per channel into 8 ohms and 666 watts into 4 ohms, with the ability to deliver up to 1100 watts into 2 ohms. It operates in Class-A for the first 10 watts before switching to Class-A/B, ensuring high current and dynamic control. The amplifier features a true dual mono configuration with a massive 2200VA dual mono Holmgren toroidal transformer and 68,000µF reservoir capacitance per channel, providing enormous dynamic headroom and low noise. The circuit uses zero global negative feedback and ultra-wide bandwidth (0.1Hz to 350kHz) for accurate transient reproduction. It includes a microprocessor-controlled 50-step relay volume attenuator with ultra-precision resistors for transparency. Connectivity includes four line inputs (two balanced XLR, two unbalanced RCA), dual subwoofer outputs, tape loop, USB for firmware updates, and 12V trigger inputs/outputs. Optional modules include the DAC-3 module with ESS Sabre ES9039PRO DAC and the PS-3 phono module with true dual mono Class-A topology. The amplifier weighs 50.6 kg and measures approximately 24.5 x 46.8 x 44.3 cm. It is designed for audiophiles seeking a powerful, transparent, and versatile integrated amplifier with expandability for digital and vinyl sources.
