Gryphon Diablo 333

Introducing the Gryphon Diablo 333 Integrated Amplifier, the latest masterpiece from Gryphon Audio Designs, setting a new benchmark in audio excellence. Building on the legacy of the acclaimed Diablo 300, the Diablo 333 surpasses its predecessor in every aspect, redefining what an integrated amplifier can achieve.

The Diablo 333 boasts a 10% increase in output power over the Diablo 300, thanks to advancements in circuitry and components borrowed from Gryphon's flagship models, the Apex Amplifier, and Commander Preamplifier. This includes ultra-fast pre-driver transistors for enhanced musicality, identical output devices to the Apex for superior performance, and a massively augmented power supply with an oversized transformer and filter capacitance for incredible dynamic headroom.

Visually stunning, the Diablo 333 features Gryphon's signature triangular display panel with a 4.3” TFT capacitive touch screen, custom-made chassis spikes for stability and harmony, and bespoke binding posts from the Apex for a luxurious finish. The remote handset, crafted from billet aluminum, offers a more intuitive user interface, while a USB 2.0 socket simplifies firmware upgrades.

For audiophiles seeking the ultimate listening experience, the Diablo 333 offers optional Phono and DAC modules, redesigned for improved performance. The PS-3 Phono Module features True Dual Mono Class A-coupled topology with discrete balanced circuitry, while the DAC-3 D/A Module incorporates the latest Sabre DAC for exceptional sound quality.

Whether you're a proud owner of the Diablo 300 or aspire to own the best, the Diablo 333 stands as a new icon of perfection in integrated amplifiers, surpassing its predecessor in performance, connectivity, and parts specification. Experience the new definition of perfection with the Gryphon Diablo 333 Integrated Amplifier.


The DAC3 is the perfect match for the new Diablo 333 integrated amplifier, adding 5 top notch digital inputs to the Diablo 333 existing four analog inputs.

With the DAC3 module build in, the Diablo 333 display informs you about the chosen digital input Sampling frequency, PCM/DSD format and digital filter setting.
