The Gryphon Diablo 333

The Gryphon Diablo 333

Improving upon perfection and thereby surpassing the legendary Diablo 300 was no simple feat: introduced at High End Munich 2015, the Diablo 300 established a new benchmark in Integrated Amplifier performance. With unanimous praise from the High End press and thousands of units sold, Diablo 300 has maintained its “Best-in-Class” status for nearly a decade, repeatedly besting newer and more expensive competitors.

Over the past eight years, however, new component technologies and intensive engineering research have suggested areas for improvement. Circuit highlights from the new Apex and Commander, Gryphon’s flagship Amplifier and Preamplifier, have “Trickled-Down” to the Diablo 333, which boasts ten percent more output power than its legendary predecessor. New ultra fast, low-capacitance pre-driver transistors deliver both enhanced musicality and superior measured performance.
