Diablo 333

Why it is renowned

Stereophile reviewed the Diablo 333 in December 2024, noting that it replaced the Diablo 300, made since 2016, and that its name gives its output into 8 ohms.¹ Hi-Fi News also reviewed it, and later compared the liveliness of its sound with that of the Antileon Revelation.² Gryphon's product archive lists the Diablo line back to the first Diablo of 2005.³

The story

Tom Møller designed the circuits and Flemming E. Rasmussen the case, whose triangular display with a touch screen follows the look he drew for the Apex and the Commander preamplifier.⁴ Parts and circuits came down from those flagships: the output transistors, ten a channel, are the same as in the Apex, and the binding posts were made for it.⁴

It is a dual-mono design with a Holmgren toroidal transformer, a 43-step balanced relay volume control and an output of 333 watts a channel into 8 ohms, 666 into 4.⁴¹ Optional modules add a balanced phono stage, the PS3, and a DAC.⁴¹ The amplifier weighs 50.6 kg (112 lb), and it is designed and built in Denmark.¹⁴
