Audio enthusiasts and connoisseurs around the globe are set to experience a new standard of excellence with the Gryphon Audio Diablo 333 integrated amplifier. Building upon the legendary success of its predecessor, the Diablo 300, this latest model is poised to redefine the integrated amplifier market, combining cutting-edge technology with remarkable aesthetic appeal.

Since its introduction in 2015, the Diablo 300 has been hailed as the finest integrated amplifier ever produced, earning accolades and a devoted following for its exceptional performance and luxurious design. Surpassing such an iconic product was no small task, but Gryphon‘s Chief Designer, Tom Moeller, alongside the artistic vision of Founder Flemming Rasmussen, has engineered a truly extraordinary successor.

More output power

The Diablo 333 offers ten percent more output power than the Diablo 300, but its enhancements extend well beyond just wattage. Utilizing advanced circuit designs and high-performance components from Gryphon’s flagship Apex and Commander amplifiers, the 333 incorporates ultra-fast pre-driver transistors that elevate both musicality and measured performance. With ten output devices per channel identical to those found in the Apex, the amplifier ensures an unparalleled dynamic range and sound clarity.

Weighing in at an impressive 50.6 kg (112 lbs), the Diablo 333 boasts a dual-mono power supply featuring an oversized Holmgren transformer and 68,000μF per channel filter capacitance, providing the headroom necessary for even the most demanding audio passages.

Striking Gryphon DNA

Visually, the Diablo 333 retains the striking Gryphon DNA, showcasing a triangular display panel with a 4.3-inch TFT capacitive touch screen, custom chassis spikes for stability, and bespoke binding posts. It offers a generous array of connectivity options, including dual subwoofer outputs, a tape loop, and the ability to select between XLR and RCA “Unity Gain” home theater throughput.

Upgrading the user experience, the remote for the Diablo 333 has been sculpted from billet aluminum, now featuring an intuitive menu structure that simplifies operation. A USB 2.0 socket on the rear panel allows for easy firmware updates, ensuring that the amplifier remains at the cutting edge of technology.

Optional modules

For audiophiles looking to expand their setup, the Diablo 333 supports optional phono and DAC modules, both entirely redesigned for enhanced performance. The PS-3 Phono Module features True Dual Mono Class A-coupled topology, without global negative feedback, ensuring the utmost sound fidelity. Additionally, the new DAC-3 module employs the state-of-the-art ES9039PRO Sabre DAC, providing a full range of inputs and seven selectable PCM digital roll-off filters.

While the Diablo 300 continues to be a highly regarded option for integrated amplification, the Diablo 333 stands as a benchmark for those seeking nothing but the best. Unity between performance, connectivity, parts specification, and aesthetic value make the Diablo 333 a true icon in the world of high-end audio.

With the Diablo 333, Gryphon Audio sets a new definition of perfection in integrated amplification. Enthusiasts and purists alike are invited to discover a world of pure musical enjoyment and unparalleled audio fidelity that only Gryphon can deliver.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
