Gryphon Audio’s Diablo 333 Amplifier Wins Prestigious Award

The Gryphon Audio Diablo 333 has secured the esteemed Temptation Award from What Hi-Fi? for 2025, marking a significant recognition in the high-end audio industry. Priced at £24,500, $24,900, or AU$39,995, the Diablo 333 stands out not only for its price but also for its exceptional performance and craftsmanship.

At a weight of approximately 50 kg, the Diablo 333 is substantial yet manageable for a high-end integrated amplifier. The standout feature is its impressive power output of 333 watts per channel into an 8-ohm load. This figure positions the Diablo 333 as potentially the most powerful domestic amplifier tested by What Hi-Fi? in its nearly 50-year history. When the impedance is halved, the power output nearly doubles, reaching an astonishing 1,100 watts per channel into 2 ohms.

Design and Features

The design of the Diablo 333 adheres to Gryphon Audio’s signature aesthetic, characterized by a sleek black finish. The build quality is exceptional; every panel aligns perfectly, showcasing meticulous machining and attention to detail. While high-end integrated amplifiers often lack extensive features, the Diablo 333 prioritizes performance over frills. It includes four inputs, among them two balanced XLRs, and offers both fixed and variable line-level outputs.

For those seeking additional functionality, Gryphon provides optional modules such as the PS3 phono stage priced at £4,950 or $5,600, and the DAC3 digital-to-analogue converter at £6,950 or $7,000. While these additions come at a premium, they are designed to enhance the amplifier’s capabilities.

Performance and Sound Quality

The Diablo 333 excels in delivering powerful sound. During testing, it handled demanding bass tracks from artists like Massive Attack and Nitin Sawhney with remarkable ease. The amplifier produced deep, punchy low frequencies and maintained composure even at high volumes.

Listeners can expect dynamic soundscapes, with large-scale orchestral pieces like Stravinsky’s The Rite of Spring showcasing the amplifier’s capacity for dramatic crescendos. The presentation is notably clear and spacious, creating a soundstage that feels expansive and stable.

Gryphon Audio’s engineers have successfully combined power with finesse, allowing the Diablo 333 to perform delicately when needed while also delivering impactful sound. This balance of strength and grace is a rare talent in the world of high-end audio, making the Diablo 333 a standout choice for audiophiles.

In a competitive market filled with world-class integrated amplifiers, the Gryphon Audio Diablo 333 emerges as a top contender. Its winning of the What Hi-Fi? Temptation Award for 2025 serves as a testament to its exceptional performance and build quality, securing its position as a leader in the audio industry.
